The "14th Five-Year Plan for the Development of Urban Domestic Waste Classification and Treatment Facilities" clearly points out that existing landfill facilities have become new risk points for the ecological environment. Most of the landfill waste has not been harmlessly treated, which may cause serious secondary pollution to the surrounding environment. Some old landfill facilities are saturated and the landfill cycle has ended. The transformation cost is high and the difficulty is high. It is a top priority to carry out ecological remediation of old landfills to transform them into usable land resources, and at the same time to make resource utilization of mineralized waste in landfills, and to reasonably choose in-situ or ex-situ governance.
After the landfill is closed for several years, the degradable substances are basically completely degraded, the amount of leachate and gas produced is very little or no, and the organic matter content drops to less than 10%. The garbage formed is called mineralized garbage.
For mineralized garbage, it can be finely divided into two categories according to recycling technology: one is materials that can be directly recycled, which will be treated ex-situ and recycled; the other is materials waiting for further transformation and utilization after technological transformation. These materials are stored in situ after classification, and the landfill is transformed into a temporary storage place. Pre-screening and processing of mineralized waste resource utilization is a top priority!
The mobile screening station can screen the material into three levels according to the particle size (the discharge particle size is based on the customer's on-site needs) and move it within the field under traction. It is widely used in material screening and grading operations in the fields of domestic waste, soil remediation, mineral processing, coal, chemicals, construction materials, solid waste treatment, etc. It can also be used in soil stabilization/solidification treatment projects.
The mobile screening station is mainly composed of chassis frame, belt conveyor, two-layer vibrating screen (bar screen + screen), hopper, tire, electronic control device and other parts. It has the advantages of integrated design, small footprint, high screening efficiency, large processing capacity, low operating energy consumption, low working noise, fast transfer, and low operating cost.
