Process Introduction

Landfill domestic waste screening treatment is a core pretreatment technology for aged waste in existing landfills or raw mixed domestic waste. Through the combined process of mechanical crushing + multi-stage screening + precise sorting, it realizes component separation according to particle size, specific gravity and material, providing stable raw materials for subsequent resource utilization and harmless disposal.

Production Line Overview

This production line is specifically designed for the resource recovery of legacy waste (aged waste) from landfills. Through mechanical screening, component separation, and the removal of impurities, it effectively categorizes materials into humus-rich soil, combustibles, metals, and inert aggregates. This process facilitates the reduction, harmless treatment, and resource reuse of existing landfill waste, aligning with national policy directives for “Zero-Waste City” development and the management of legacy solid waste.

The production line integrates a slat conveyor feeder, a trommel or vibrating screen, an air-classification system, magnetic separators, a manual sorting platform, a conveying system, and an intelligent control unit. Core components are constructed from anti-corrosive and wear-resistant materials, ensuring durability in environments characterized by high humidity and high corrosivity. The system efficiently separates components such as plastic films, textiles, wood/bamboo, ferrous metals, stones, and organic humus, preparing them for subsequent resource recovery or safe landfill disposal.
