Product Introduction
The Z-Type Air Separator is a vertical zigzag airflow sorting machine purpose-built for efficiently separating heavy and light materials in mixed solid waste. It specializes in fine light impurity removal from crushed materials, accommodating items up to 60 mm. Widely applied in municipal solid waste, aged waste, construction and renovation waste, recycled plastics, and industrial residue scenarios, it serves as a core sorting unit for the solid waste resource recovery and recycled material reclamation industries.
The machine features a vertical Z-shaped zigzag duct structure. A fan generates a stable upward airflow. As materials descend, they collide and tumble across multiple stepped tiers where agglomerated materials break apart. Heavy materials such as brick, stone, metal, and plastic bottle flakes overcome air resistance through inertia and descend along the duct to discharge, while lightweight impurities such as film, paper scraps, and fibrous dust are carried upward by the airflow and collected and separated via the top cyclone dust collector. The zigzag flow field design effectively avoids the uneven sorting accuracy issues of straight ducts, achieving high-purity heavy-light separation and addressing pain points of conventional air separators such as incomplete separation and susceptibility to material blockage.
The equipment features a compact overall structure with strong airtightness. The fully sealed process design minimizes dust leakage, while the cyclone dust removal system simultaneously purifies the operating environment. It is equipped with a variable-frequency drive fan and electrical overload protection, allowing flexible airflow adjustment based on material characteristics. The modular structural design facilitates maintenance and repair, with low operating noise and a low failure rate, making it well-suited for long-term continuous industrial operation with exceptional versatility and practicality.
Key Advantages
The equipment delivers excellent overall airtightness with a reliable sealing design. Settlement chamber joints are sealed with sealant, and sealing gaskets are installed at all duct connections, effectively reducing air leakage and dust escape while ensuring stable overall airtightness. The equipment includes a dedicated dust removal unit that collects dust generated during operation in real time, significantly improving the on-site working environment and reducing dust pollution to meet environmental and workplace safety requirements. The feed inlet and discharge outlet are equipped with rotary star valves, ensuring uniform and stable material feed and discharge while further strengthening the overall sealing performance of the equipment.
The fan is equipped with a variable-frequency motor allowing adjustable impeller speed. Speed can be flexibly adjusted in real time based on material type, moisture content, specific gravity, and throughput, precisely matching the optimal sorting conditions, stably controlling airflow intensity and sorting trajectory, and effectively improving light/heavy material separation accuracy and purity to meet diverse material sorting requirements and ensure efficient, stable operation.
The spacing of the equipment’s Z-shaped deflection plates can be precisely adjusted via a dual-lead-screw mechanism, enabling flexible adjustment of the sorting channel width based on material type, particle size, and sorting requirements to achieve optimal sorting results under varying operating conditions with strong adaptability. Ducts and the main equipment body are connected using flexible hoses, effectively compensating for assembly tolerances and providing sufficient installation redundancy to prevent assembly failure due to manufacturing or installation deviations.
A professional electrical overload protection system automatically triggers an alarm and shuts down the equipment in the event of overload operation or current anomalies, preventing damage from overloading. The main structure uses galvanized steel plate with a modular design. The fan and motor are connected via V-belts, enhancing rotational stability and adapting to high-dust, high-impact complex operating conditions. The fully enclosed structure reduces dust erosion, while flexible sealing components and the vibration damping system reduce operating wear. The equipment demonstrates strong overall durability and extended service life.
