Heavy screening combinations are required for the treatment of stale garbage in landfills. The vibrating screen separates humus from impurities such as plastic and glass through high-frequency vibration. The flexible screen of the bouncing screen produces wave-like motion under the action of the pneumatic device, effectively removing the blockages in the screen holes. In the treatment of a closed landfill in Guangzhou, the combined equipment has an average daily processing capacity of 800 tons. The heavy metal content of the humus under the screen meets the agricultural standards after testing and is used for the reclamation of surrounding land, reducing the cost of a single treatment by 30%.
The stale garbage treatment equipment in landfills breaks through the difficulty of sorting sticky materials. The bar relaxation screen uses variable-section elastic rods, which produce a "self-cleaning" effect of compacted garbage through high-frequency vibration. With the wind sorting system, it can separate humus, plastic, fabric and other components. In the treatment of a landfill in Zhengzhou, the equipment has achieved a screening efficiency of 85%, and the average daily processing capacity has exceeded 200 tons, providing stable raw materials for subsequent incineration power generation.
