Tailings are the by-products of mining processing, typically containing moisture levels as high as 30%-60%. They are not only difficult to store but also pose significant environmental risks. Our Tailings Dryer is specifically engineered to handle high-humidity, high-viscosity mining waste. Through efficient dewatering and drying, it converts tailings into reusable dry materials (such as raw materials for brick making, mine backfill, or feed for further metal extraction), helping mining companies achieve "zero discharge" and resource recycling.
Our equipment is widely used in the following mining scenarios:
Metal Tailings: Iron tailings, Copper tailings, Gold tailings, Bauxite tailings.
Non-metallic Tailings: Graphite tailings, Fluorite tailings, Silica sand tailings.
Chemical & Coal Waste: Coal slime, Phosphogypsum, Red mud.
Our equipment utilizes Direct Heating Rotary Cylinder Drying Technology.
Feeding: High-moisture tailings are fed into the dryer cylinder via a conveyor.
Breaking & Granulating: The cylinder is equipped with a unique combined lifting plate and breaking device. For sticky tailings, the equipment forcibly breaks them apart, increasing the contact area between the material and the hot air, thoroughly solving the common issues of "blockage" and "agglomeration" found in traditional equipment.
Heat Exchange: High-temperature airflow generated by the hot air furnace (fueled by coal, natural gas, biomass, or waste heat) fully contacts the tailings inside the cylinder for efficient heat exchange.
Discharging: The dried tailings are discharged via a discharger, while the exhaust gas is treated by a high-efficiency dust removal system (baghouse filter) to meet emission standards.
