E-waste" is also known as "electronic waste", all unused electronic equipment is electronic waste. For its treatment, a double-shaft shredder is most suitable.Types of electronic wasteThere are many types of e-waste, which can be broadly divided into two categories: one is the material contained in a relatively simple, less harmful to the environment of waste electronic products, such as refrigerators, washing machines, air conditioners and other household appliances, as well as medical and scientific appliances, such products are relatively simple to dismantle and dispose of; the other is the material contained in a more complex, more harmful to the environment of waste electronic products, such as computers, televisions, lead in the picture tube, computer components containing arsenic, mercury and other harmful substances, mobile phones in the raw materials of arsenic, cadmium, lead and a variety of other persistent and bioaccumulative toxic substances.Mechanical treatment of e-wasteMechanical treatment of

What is scrap metal？Several kinds and also large amounts of metals are used in industrial processes every day, metal is therefore crucial to sustaining our living standard. Therefore, there are also so many scrap metal are produced everyday. From industry, living, mining and many other channel, we produced so many scrap waste.What's the damage of scrap metal?The huge scrap metal make many damage to our earth. The production of scrap metal results in a significant depletion of natural resources; Metal waste also indirectly contributes to the global warming problem; Also pollute the earth, the air, water and so on. So proper scrap metal recycling is important.What's the process of scrap metal recycling?Usually, several steps are needed for the scrap metal recycling.1.Collecting: Depending on the value of the metals, scrap metals can either be collected for recycling purposes or end up in landfills. Metals not valuable enough will be dumped into landfills while precious metals will be collected in order to

Waste tires are large in volume, large in quantity, difficult to degrade and flammable. Their characteristics make a large waste of land resources. At the same time, they also cause great problems to relevant departments in terms of safety.Waste tires are classified as "waste", but its value can not be underestimated. It contains a lot of metal and rubber, has high recycling value, is a misplaced resource, and has the reputation of "black gold mine". The disposal process of waste tires is relatively complex. Different equipment of tire shredder and shredding line will be selected for processing according to different finished products and size requirements. The common disposal applications are as follows: tire grinding, cracking oil refining and cement kiln incineration.After the tire is shredded, it also needs to be ground by a pulverizer to process the tire particles to different mesh numbers. The rubber powder with different mesh numbers can be used for different purposes, such as rubber runway, recycled

Fabric recycling backgroundCurrently, the total amount of garbage in the world is increasing year by year at an unpredictable rate. With the implementation of policies in various countries, many cities around the world have successively entered the era of mandatory garbage classification and recycling. For example, waste textile waste generated or discarded in industrial production and people's lives actually has a high added value. They can be used as high fuel value RDF/SRF fuel or for further processing.Gep industrial fabric shredder machinefabric double shaft shredderfabric single shaft fine shredderGep series fabric shredder working principle:Through tearing, large pieces of tangled fibers are loosened into small pieces or bundles, and the process of loosening is accompanied by mixing and de-mixing. The crushed fabric waste can achieve high utilization value, reduce environmental pollution, reduce transportation and storage space, etc.Gep series fabric shredder strengths:1.

The damage of plastic wastePlastic products take great convenience to our life, but the pollution made by plastic also cause serious problem over the world. Plastic pollution has become one of the most pressing environmental issues, as rapidly increasing production of disposable plastic products overwhelms the world’s ability to deal with them.Every year, about 8 million tons of plastic waste escapes into the oceans from coastal nations. Plastics often contain additives making them stronger, more flexible, and durable. But many of these additives can extend the life of products if they become litter, with some estimates ranging to at least 400 years to break down.How to recycle the plastic waste?Comparing with the great damage made by plastic waste, the recycling work of plastic waste is not very well. Usually, there are several steps to recycle plastic waste:1.Collection of Waste Plastic2.Sorting of Plastics into Categories3.Washing to Remove Impurities4.Shredding and Resizing5.Identification and Separation

The treatment and disposal methods of animal carcasses mainly include chemically refined oil, direct landfill, landfill disinfection, composting, direct incineration, and incinerator incineration. In order to speed up the efficiency of landfilling or burning, animals must be pre-crushed. The purpose of crushing animal carcasses before incineration is to reduce the volume of large animals entering the incinerator, eliminate gaps, and make the size and texture of crushed animal carcasses uniform, which is more conducive to combustion and improves incineration efficiency.Animal carcass crusher is an important equipment that can crush animal carcasses. This article will take you to learn about carcass animal crusher China.Application of animal carcass crusher ChinaDestroy expired food and substandard foodDisposal of dead and sick animalsReduce the size of animal bones and meatFeatures of animal carcass crusher ChinaAnimal carcasses are quickly crushed and processed immediately after entering the crushing

Governments all over the world are faced with how to manage municipal solid waste. Although strengthening recycling technology can reduce a large part of waste, a large part of municipal solid waste is still landfilled. Landfill means waste of resources. Moreover, dangerous toxins can leach into soil and water and produce methane (CH4) and carbon dioxide (CO2) emissions, which can lead to climate change. The RDF production line can convert a large part of the municipal solid waste into RDF for reuse. It is a good helper for the recycling of municipal solid waste. Let us briefly understand it below.The process of RDF plantIn order to produce standard solid fuel, municipal solid waste goes through a series of processes. Domestic waste contains many different materials, which need to be mechanically separated into high-calorie and low-calorie parts. This process involves crushing, screening and sorting materials. Remove metals, inert substances and organic matter; light substances with high calorific value (
