The main components of waste tires are rubber, steel wire, and fiber filaments. The recycling method is to separate the steel wires and fibers inside the waste tire through various technologies and grind the rubber block into rubber particles or rubber powder to prepare reclaimed rubber. Its advantage is that the utilization rate of waste tires can reach 100%, can be recycled, and there is no secondary pollution in the process. The recycling of waste tires to produce environmentally friendly reclaimed rubber is an environmental protection development model that integrates environmental protection and resource reuse.

The raw material for the production of reclaimed rubber is mainly rubber powder. The rubber powder mainly comes from waste rubber. The source of waste rubber is mainly waste rubber products, that is, scrap tires, tires, hoses, tapes, rubber shoes, industrial miscellaneous goods, and those produced by rubber enterprises. 70% of waste rubber comes from scrapped automobile tires. Disposing of waste tires is a strategic industry that solves black pollution and promotes resource recycling. It is a good thing that benefits the country and the people.

In order to promote the crushing of waste tires at room temperature and improve the quality of rubber powder, many machinery manufacturing companies have developed and produced dual-shaft tire shredders and realized automation. The tire recycling machines is equipment for automatic crushing of rubber powder. Notable features are normal temperature, automation, low noise, and low dust.

As the country becomes more stringent in environmental protection emissions, more and more industry companies are able to actively upgrade environmental protection equipment, continuously increase investment in environmental protection, and consciously achieve clean production. With technological transformation and upgrading, the production outlook of the entire industry has also been greatly improved. With the joint efforts of industry enterprises, the overall production outlook of the comprehensive utilization of waste rubber industry is undergoing profound changes. Strengthening technological innovation, promoting the green transformation and upgrading of the industry, and achieving green development are becoming the consensus of the industry.

Regular pruning of garden landscape trees

In the garden landscape, hedgerows need to be trimmed into various shapes. To maintain the graceful shape of the hedgerow, it is necessary to trim the crown regularly and encourage the side buds of the hedgerow to germinate, so as to make the tree shape fuller and more realistic.
The street trees in cities include phoenix tree, locust tree, albizia flower, camphor tree, etc. In order to make the trees tall and beautiful, with lush branches and dense flowers, pruning is an indispensable maintenance method. Garden workers often make close shearing to keep the trees with good growth and reduce pests and diseases of trees.
How to deal with pruned branches and leaves

How to deal with the discarded branches and leaves that have been pruned? Due to the rapid urban construction and the orderly and strict planning, the abandoned branches and leaves are long or short, thick or thin, with or without leaves, and some of the leaves are dry and fresh, very messy, and cannot be stacked on open spaces.

So can it be transported out of the city by large trucks? The answer is no. One: urban traffic is congested, and trucks transporting discarded branches and leaves are restricted during the day. Second: the volume of discarded branches and leaves is quite large, which consumes fuel and labor. Thirdly, the garden waste is not used rationally.
In the last century, municipal gardens, schools, and homes in developed countries in Europe and the United States generally used branch shredders. The use of the tire shredder machine realizes the reduction, harmlessness and recycling of resources for garden greening waste. It is actually a scientific and energy-saving environmental protection equipment, which is well received by users. Yuxi sawdust maker machine is widely used to crush the discarded branches and leaves in urban landscaping.

Branch and leaf debris is widely used

The crushed sawdust is piled and sterilized to cover the basic soil surface of the tree to produce organic fertilizers, substrates, and pressed into boards, and then re-applied to the greening and maintenance of the garden. The most common is sawdust cover, and it is used rationally. Wooden coverings have a high use value and serve multiple functions. For example, 1. Keep the loess in the open air, prevent dust on the spot, and purify the air. 2. Slow down water evaporation, keep moisture and save water. 3. Prevent soil compaction and weed growth, reduce management workload. 4. No soil erosion. 5. Soil insulation. 6. Wood decomposes to increase fertility. 7. A variety of colors and beautify the environment.

With the development of the times and the continuous progress of society, people pay more and more attention to the influence of living conditions and the environment, and at the same time, people pay more and more attention to the protection of the environment. A good living environment not only brings good mood, but also guarantees health. The improvement of living standards also makes auto industry develop rapidly.
Waste tires are growing rapidly every year, and the increasingly serious pollution has made our fragile ecological environment even worse. At the same time, tires have a limited lifespan. Discarded waste tires are insoluble or refractory materials, which have strong heat resistance and mechanical corrosion resistance, and will affect the ecological environment within a century and cause serious pollution. If this pollution is not dealt with as soon as possible, it will cause great harm to the environment, and the waste will always affect our living environment. In order to deal with this kind of garbage and reuse some of the available resources, tire shredders are produced, and the emergence of waste tire recycling line solves the problem.

The tire shredder has the characteristics of low noise, low energy consumption and high output. It fully reflects the advantages of low-speed high-torque shearing design. This series of waste tyre shredders are widely used in the recycling of large-volume wastes such as waste plastics, waste rubber, and wood. Cutting with the machine can increase the bulk density of the material and reduce shipping costs. The crushed material can be further processed by other equipment, such as material sorting, separation and cleaning. The tire shredder solves the problem of waste tires pollution.

The purpose of the double-shaft tire shredder is to reduce the size of the material by cutting, tearing and squeezing. This type of shredder is widely used in shredding waste plastic, waste rubber, wood, metal and other waste materials. However, there are many things to be aware of when using it.

1. After buying the double-shaft tyre shredder equipment, you must first read the relevant instruction manuals carefully. The operator should be familiar with the operation and maintenance methods of the double-shaft shredder, so as to avoid unnecessary accidents due to the unskilled operators.
2. Before the double shaft waste tyre shredder startingto work, check whether there is any residue in the shredding cavity. It cannot be started with a load, because starting with a load will cause electrical tripping or damage to parts, so check the inside of the shredding cavity before working. If there is any residue, removethem before starting the equipment.
3. Maintenance work is very important. Regular inspection of the wear and tear of the equipment can reduce unnecessary wear and tear caused by the long-term use of the equipment. At the same time, doing maintenance work can make the machineplay a good role.
4. If there is a sudden power failure during working, turn off the power of the equipment first, so as to avoid unnecessary damage to the shredder caused by a sudden call.

Terrazzo floor tiles refer to the ground with smooth surface made by special process by embedding stones and fragments in the cement mixture. Terrazzo floor tile is a kind of composite floor building material with cement as the main raw material. It’s widely used in large-area public buildings due to its low cost and good performance.

Ordinary terrazzo floor tiles are originally used in homes or factories. They use primary color cement, glass dividers, and ordinary stones, and the gloss is not very smooth. Now, there is a good improvement in gloss of the new terrazzo floor tiles.

Although terrazzo floor tiles can be used for many years, they will also experience wear, especially when they are used in outdoor and other public areas. For reducing weathering and abrasion of terrazzo floor tiles, the best way at home and abroad is to clean the dirt on the stone surface and put it on a layer of wax. This method can protect the surface of the new terrazzo floor tile to a certain extent, and better delay the speed of natural weathering and abrasion.

(2) The traditional terrazzo is generally set with a dividing line within one square meter, otherwise the risk of cracking is difficult to repair; the new-type terrazzo doesn’t need to design the dividing line in a large area, and the grade is high and not easy to be cracked.

(3) The traditional terrazzo aggregate is relatively dense, the aggregate type is single, the aggregate is too small or too little, easy to crack, and the decorative effect is limited; the new-type terrazzo can use a variety of different aggregates, which can be freely combined to display colorful decorative effect.

(4) Traditional terrazzo is difficult to display complex pattern effects. The new-type terrazzo can be freely combined by designers to achieve effects such as pattern, color and art, so that terrazzo can show the personality and unique charm of the architectural space.

With the sustained and rapid development of world's national economy, the amount of municipal solid waste is increasing, and the waste treatment industry has also developed rapidly. Incineration of garbage and energy recovery to achieve volume reduction, harmlessness and resource utilization of MSW is considered an important direction for the treatment of MSW. Due to the complex composition and low calorific value of domestic waste, if it is directly incinerated without sorting and classification, the toxic and harmful gases will be generated during the incineration process, and the toxic and harmful gases will be discharged into the atmosphere when the incineration temperature is not high enough, which will cause air pollution.

Yuxi intelligent MSW sorting line includes bag breaking machine, screening machine, sorting machine, the first magnetic separation machine, winnowing machine and the second magnetic separation device. The bag breaking device, screening device, sorting device, the first magnetic separation device and the winnowing machine are sequentially connected by the conveyor belt, and the screening machine is also connected with the second magnetic separation equipment.

Yuxi automatic MSW sorting machine can automatically discriminates different types of urban domestic garbage, the manipulator performs actions, and the machine works intelligently, thereby reducing labor intensity, saving labor costs, overcoming the problem of domestic garbage landfill or incineration, and eliminating the secondary waste generated after the incineration of domestic garbage. Yuxi Municipal Solid Waste separation line can realize the classification and utilization of domestic waste, improve the gas production efficiency, and realize automatic management.

How to dispose of large household garbage such as discarded furniture, tables and chairs, sofas, mattresses, and sundries is a problem for many people. Some citizens throw waste bulky garbage everywhere, which not only destroying environmental sanitation, but also encroaching on public places. In order to ensure the cleanliness and sanitation of the city, it is particularly important to do a good job in the end treatment of domestic garbage in the city.

How to Process and Sort the Domestic Waste?

People place bulky waste into designated storage locations. The person responsible for the management of bulky waste shall deliver the bulky waste within the scope of its management to sanitation operation service department for clearing or transporting to the bulky waste sorting center in a centralized and standardized manner. The garbage sorting centers do centralized disposal of bulky garbage, screen and sort the bulky garbage with reused value to reuse; disassemble and sort the bulky items with no value, and reuse the recyclable parts , while the non-recyclable part will be treated separately.

Yuxi domestic waste processing and sorting line mainly uses the process of "crushing + sorting", which converts the bulky waste into reusable resources through crushing and volume reduction sorting. Yuxi domestic waste sorting line is composed of a conveying system, a crushing system, a magnetic separation system, an intelligent monitoring system, and an intelligent dust reduction system. It turns bulky waste into treasure, improves the recycling rate, and truly realizes the reduction and harmless recycling of bulky waste.

"Eat" A Bulky Waste in Tens of Seconds

The bulky garbage is sent to the conveyor belt in batches and enters the high-power double-shaft shredder. The domestic waste shredder uses the principle of mutual shearing and tearing between two relatively rotating knives to crush materials. Large pieces of garbage are quickly cut and shredded into small pieces. After being crushed, the materials are transported to the magnetic separator. Under the action of magnetic force, metal objects such as nails, iron wires, and iron sheets will be automatically sorted out, collected and recycled, while the rest of the materials are sent to the transfer truck, waiting for the next step of processing.

During the entire processing and sorting process, the operator can monitor the crushing and sorting process in real time through the GI intelligent monitoring system, which can effectively reduce equipment failure rate and maintenance time, reduce maintenance and operating costs, and greatly improve the working efficiency of the bulky waste sorting line. The MSW sorting line adopts a closed design in the crushing and blanking area, and is equipped with an intelligent central dust removal system, which effectively suppresses the generation of dust and greatly improves the environment for large-scale garbage process.

How to judge whether the cutting tool needs surfacing repair?

1. When the edge of the cutting tool is worn to form a fillet of about R3, it needs to be repaired.
2. If the discharging granularity becomes larger, and the shredder jams or frequently reverses when it is working, the cutting tool need to be repaired.

How to repair cutting tool of metal shredder machine?

1. Remove the cutting tool from the shredder machine after confirming that the cutting tool meets the repairable conditions.
2. Clean the cutting tool, remove surface oil stains and other matters that affect welding.
3. Preheat the cutting tool as needed.
4. For welding worn surfaces, the welding wire should select imported wear-resistant welding wire with good bonding performance and high hardness. The hardness of the welding wire is 55-60HRC and 50-55HRC. The service life after repair is determined by the material for renovation.
5. For machining according to the drawings, the thickness of the cutting tool is important, which affects the service life of the cutting tool.
6. Acceptance of cutting tools.
7. Installed.

Note: Generally, cutting tools can be repaired more than 3 times.

In order to ensure the welding quality of the blade, the blade after being welded should be carefully inspected to find out the cause of the defect and improve it. Before inspection, the blade should be sandblasted or lightly ground to remove the solder and impurities adhering to the surface of the blade, and cleaned with kerosene.

The inspection items and requirements are as follows:

1. Check the strength of welded joint: Grind the back of a blade with a green silicon carbide grinding wheel, and check the thickness of the solder layer, the thickness is required to be below mm. There should be no pores and insufficient solder on the bottom surface of the cutting tool tip bearing, and the weld that is not filled with solder should be no more than 10% of the total length of the weld. If there are air holes, the blade will fall off during cutting.
2. Check the position of the blade in the slot: If the blade is misaligned or sag in a unnormal conditions, re-welding is necessary.
3. Check the welding strength: Hit the blade with a wooden hammer or a copper hammer with medium strength, it’s qualified f the blade does not fall off the knife body. To check the welding strength of the blades, you do not need to check all of them one by one, spot checks is OK.
4. Check the flatness of the blade: If there are obvious pits on the blade, it means that the blade is overheated and deformed, and the blade should be burned and re-welded.
5. Check the cracks: After the blade is cleaned with kerosene, if the blade has cracks, kerosene will penetrate into the cracks and appear black lines, which can be observed with the naked eye. It can also be observed with a magnifying glass of 10-40 times.

Color flaw detection can also be used to check the blade cracks: Make a solution of 65% kerosene, 30% transformer oil and 5% turpentine, and a little Sudan red. Put the blade in the solution for 10-15 minutes, then wash it with water, apply a layer of white clay (kaolin), and observe the surface after drying. If there are cracks on the blade, the color of the solution will be appeared on white clay, and can be seen with the naked eye. The cracked blade cannot be used and needs to be re-welded.

With the continuous increase of urban green coverage, garden waste disposal has also been put on the agenda. These garden wastes are different from domestic waste and industrial waste because they are rich in organic matter and nutrients, and are of great ecological and economic value.

If these garden wastes are only landfilled or incinerated, it will not only waste biomass resources and occupy land resources, but also increase the cost of waste treatment. Therefore, recycling them is an inevitable choice.

At present, there are 4 ways to dispose of garden waste:

1. Organic mulch: This is a very common environmental protection treatment method. It can be treated on site, and can suppress dust, improve soil, control weeds, and reduce pests and diseases.
2. Making organic fertilizer or substrate: The crushed waste can be decomposed and fermented to make organic fertilizer. The scale can be large or small, which can improve soil and increase fertility, but the production process requires certain site and technology.
3. Processing into biomass fuel: garden waste can be made into biomass fuel after crushing, sorting and other processes, which is used for incineration and power generation in power plants.
4. Pressing into wood board: It needs to be produced by professional manufacturers, and has certain requirements on raw material specifications. Generally, clean and thick branches are required.

Zhengzhou Yuxi Machinery can provide the shredding equipment required for the recycling of garden waste - garden waste shredder. Our other main products are tyre shredder, metal shredder, double-shaft shredder, single-shaft shredder, tire recycling line, domestic waste sorting line, sawdust making machine, scrap metal crushing and recycling line, etc. Welcome to leave us a message and visit our factory.

With the large-scale use of rubber products, the problem of waste rubber pollution has become more and more serious. The waste rubber mainly comes from scrapped automobile tires. The rapid development of the automobile industry has continuously increased the generation rate of scrap tires. How to realize the recycling and utilization of waste rubber is of great significance to the sustainable development of rubber industry.

It is understood that the current disposal methods of waste tires mainly include the production of reclaimed rubber and retreading. In our country, the processing methods of waste tires are mainly based on the production of reclaimed rubber, which has developed rapidly in recent years.

The emergence of reclaimed rubber is a dawn to solve the problem of "black pollution". Reclaimed rubber not only solves the current pollution problems of waste tires and waste rubber, but also alleviates the current shortage of rubber resources. Making waste rubber to reclaimed rubber is the best solution to solve the problem of "black pollution" other than retreading, which accounts for as much as 60% of the total recycling of used tires.

Therefore, the problem of recycling and utilization of waste tires has attracted more and more attention from all walks of life, and the business opportunities contained in it have also been favored by related companies and investors. In recent years, many reclaimed rubber companies have basically achieved pollution-free production after technological transformation, and are moving in the direction of "green industry", bringing greater profits to the majority of rubber product manufacturers.

In addition to reclaimed rubber, more and more waste rubber and waste tires have also been crushed into rubber powder. The application range of rubber powder is wide. At present, rubber powder has been used to many new products such as waterproof coatings, rubber powder modified asphalt, etc., and has been well received by rubber product manufacturers after trial and use.

The "black pollution" that was hateful in the past has turned into "green wealth" in an instant. It can be seen that the reclaimed rubber and reclaimed rubber powder play a great role in the recycling of "black pollution".

What are the ways to dispose domestic waste? What are the different uses after recycling?

The composition of domestic waste is complex. The primary domestic waste includes such as plastic bags, waste paper, wood, foam, sponge, muck, metal, and leftovers. In the past, it was directly disposed of by landfill, which not only took up a lot of underground space, but also contaminate soil and groundwater. The direct incineration of domestic waste for power generation not only has low calorific value and insufficient incineration, but also produces harmful gases such as dioxins.

We can learn from many places that "garbage is misplaced resource". Therefore, with the advancement of industrial technology, domestic waste recycling system is here. The domestic waste recycling system is to smash the domestic waste with a domestic waste shredder, and then use a trommel screen, a magnetic separator, a wind separator, an organic separator, a flotation machine, a dehydrator, a RDF forming machine, an eddy current separator, and a series of equipment classify domestic waste in detail, and then efficiently recycle different materials.

After the domestic waste is processed, the wood, metal, muck and other debris are usually sorted out, and then the remaining plastic, foam, cloth and other combustibles with high calorific value are uniformly processed into RDF particles, which become an important fuel for power plants. Some non-profit domestic waste disposal centers will also directly package the combustibles in the domestic waste to the power plant for incineration treatment, and no further deep processing will be made for profit. It is also the existence of this phenomenon that many companies professionally come to purchase high-calorie-value materials sorted by such disposal centers, and then process them into high-value-added products. The domestic waste is simply crushed and then classified, the classified materials are sold separately, and the materials that are not easy to be sold are sent to the incineration plant for treatment.

Zhengzhou Yuxi Machinery has been engaged in the research and development of solid waste disposal systems and corresponding processing equipment for a long time, and has rich practical experience in this field. For example, in the disposal of domestic waste, if it is made into fuel with high calorific value, we will help enterprises to separate vinyl plastic, polyethylene film, foam, cloth, etc., and the calorific value exceeds that of thermal coal, and make it into high calorific value waste-derived fuel (RDF). Moreover, the residues after the incineration of domestic waste can also be reused as fertilizers, cement kiln synergistic materials, etc.

In a word, according to the end use and purpose of domestic waste disposal, the structure and equipment of waste sorting line can be flexibly configured to achieve high resource utilization or to produce mixed products with high calorific value.
