Product Overview
The light material separator is a high-efficiency airflow sorting system purpose-built for separating light and heavy materials in mixed solid waste. It leverages density differences for precise material sorting across a wide range of scenarios including municipal solid waste, construction and renovation waste, aged waste, industrial slag, and recycled aggregates. It is the core sorting equipment for solid waste recovery, waste classification, and recycled building materials processing.
The equipment features an enclosed settling chamber supported by a variable-frequency fan system that generates stable, controllable airflow. Separation of light and heavy fractions is achieved based on the force exerted by high-velocity airflow on materials and their density differences. After material enters the sorting chamber and spreads evenly, lightweight materials such as plastics, film, paper scraps, and textiles are drawn by airflow into the settling and collection unit, while heavy materials such as brick, concrete, metal, and glass fall and discharge along a gravity trajectory. During operation, airflow remains consistently stable with a clear trajectory, enabling contact-free, high-efficiency separation. The fan system is infinitely adjustable to accommodate different materials and purity requirements. Light materials are centrally collected after separating from the airflow in the settling chamber, while heavy materials are smoothly conveyed to the discharge outlet, completely resolving industry pain points such as screen clogging, sticky-material adhesion, incomplete light-impurity removal, and severe wear common to conventional screening equipment.
The overall structure is designed with ergonomics in mind, with the main body using modular assembly for convenient maintenance. It is equipped with negative-pressure dust collection, sealed dust suppression, variable-frequency speed control, and electrical overload protection systems, balancing sorting efficiency, operational stability, and workplace safety. The equipment also features low noise, a low failure rate, and simple disassembly and maintenance, significantly reducing operating costs and manual labor intensity. It supports long-term continuous industrial operation with exceptional versatility and practicality.
Key Advantages
The equipment adopts a sealed structural design. All joints between settling chamber modules are sealed with dedicated sealant, and duct connection points are fitted with high-density gaskets to effectively eliminate air leakage and dust emission, ensuring overall sealing performance. A cyclone dust collector is standard equipment, efficiently capturing process dust, purifying the working environment, reducing dust pollution, and fully meeting environmental and safety requirements.
The fan is equipped with a variable-frequency motor allowing impeller speed adjustment. Speed can be flexibly adjusted in real time based on material type, moisture content, specific gravity, and throughput to precisely match optimal sorting conditions, stably control airflow intensity and sorting trajectory, effectively improve separation accuracy and purity of light and heavy materials, and meet diverse material sorting requirements for efficient, stable operation.
The drum is mounted on slider bearings, allowing the distance between the drum and feed inlet to be adjusted based on material conditions. Adjustable-angle guide vanes inside the air outlet enable airflow velocity at the outlet to be fine-tuned within a certain range. A material-spreading boss is configured below the feed inlet to effectively thin the material curtain, creating favorable conditions for pneumatic sorting. Flexible hose connections between ducting and the main equipment body effectively compensate for assembly tolerances, providing ample installation redundancy to prevent fit-up issues caused by manufacturing or installation deviations.
A professional electrical overload protection system is provided. Should conditions such as overload operation or abnormal current arise, the system automatically alarms and shuts down to prevent damage from overload. The main structure uses galvanized sheet steel with a modular design, and the fan and motor are connected via V-belts for enhanced rotational stability, suitable for high-dust, high-impact operating conditions. The fully sealed structure reduces dust erosion, while flexible sealing components and a vibration damping system minimize operating wear, delivering strong overall durability and a long service life.
