The Classification of Solid Waste Crushers
Why do we need crushers to handle the solid waste? The answer is obvious. Now each of us, especially those living in cities, faces all kinds of waste every day whether we are at home or outside of the house. It can even be said that we live in a world surrounded by garbage.
Shredders /Crushers play an important role in the application of different types of solid waste. According to the type of garbage, the application of the shredder is roughly divided into the following categories:
1) Domestic waste shredder
For example, in my country, about 150 million tons of domestic waste is produced every year. After many years of stacking, these wastes have very little moisture, and their calorific value is higher than that of high-quality coal. These domestic wastes can be used to generate electricity, generate steam, and manufacture cement. According to scientific researchers, these domestic wastes must be sorted and crushed before they can be fully burned in the furnace, so the domestic waste crusher comes in handy.
2) Municipal waste shredder
As the urban population grows year by year, urban waste is also increasing. In order to reduce the accumulation of urban solid waste and sludge, the continuous enhancement of environmental awareness, and the improvement of comprehensive utilization technologies such as thermal energy recovery, countries around the world use incineration technology to treat urban waste. First, the municipal waste is shredded, and then burned in an incinerator to release heat energy, and then the waste heat can be recovered for heat or power generation. The flue gas is discharged after purification, and a small amount of residual residue is discharged, landfilled, or used for other purposes. Its advantages are rapid capacity reduction and complete high-temperature harmlessness, small footprint, less impact on the surrounding environment, and heat recovery.
3) Food waste shredder
With the improvement of people's diet, more and more garbage is thrown away in the catering industry, including various organic garbage such as hotel garbage, restaurant food waste and so on. In order to effectively utilize renewable resources, kitchen waste can be used as a feed through crushing and fermentation, and can also be used for anaerobic treatment to generate biogas.
4) Medical waste shredder
With the aging of the world's population, the overall medical level has been improved, and the amount of medical waste is also increasing. Researchers said that if medical waste is not properly disposed of, various toxic substances, toxic liquid radioactive substances, etc. will seep into the soil with rainwater, and harmful substances will enter the human body through the food chain, endangering human health. There are three main ways to effectively dispose of medical waste: 1. Disinfect and reduce the size of the waste; 2. Burn it on the spot in time; 3. If it cannot be burnt, it will be landfilled after disinfection. Both the first and second types of medical waste need to be shredded.
5) Biomass Grinder
As biomass energy, sugarcane leaves are the safest and most stable energy source, and it is also a new energy field that I have been encouraging. The dry anaerobic method is used to ferment the yellow dried sugarcane leaves into biogas. Pulverizers can be used to pulverize large quantities of sugarcane leaves into small pieces.
6) Wood Crusher
With the development of the forestry industry, wood crushers are of great significance in improving energy conservation and environmental protection.
7) Plastic drum/chemical drum crusher
In order to promote the granulation, crushing, and recycling of waste plastics, pulverizers, especially mobile pulverizers, are indispensable.
Other solid wastes, such as industrial waste, paper mill waste, vegetable market waste, etc., are also shredded separately by crushers. In a word, crushers have been playing a significant role in recycling and environmental protection.
The Application of Tungsten Carbide in the Above Crushers
The above crushers mostly use roller crushers. The material falls between the two rollers through the feeding port for extrusion and crushing. The double-toothed roller crusher adopts the counter-rotation method, the crushing teeth are bullet-type, and the surface is welded with cemented carbide, which has high strength and high crushing efficiency. Control oversized particles in the shredded product.
The crushing plate on the toothed roller is assembled, and the crushing teeth are welded with cemented carbide on the cast matrix with good toughness, which not only has high strength, but also can crush hard objects, and the crushing teeth "would rather not bend".
After years of research and development and running-in with customers, the cemented carbide welding products produced by our company have screened out suitable grades to give full play to the excellent performance of the products, with high strength, high wear resistance, high corrosion resistance, and high resistance bending performance. In addition to being used in the above-mentioned solid waste shredders in recycling, it is also used in aggregates, cement, quarry ores, mining ores, etc.
