The spiral classifier can be classified into two types based on the number of screw shafts: single screw and double screw. It can also be categorized as high weir, low weir, or immersed-type based on the height of the overflow weir.
can classify and dewater a wide range of mineral materials with particle size typically between 0.83mm to 0.15mm (20 mesh to 100 mesh), such as iron ore, tungsten ore, tin ore, tantalum-niobium ore, silica sand, feldspar, phosphate rock, and other non-ferrous and ferrous metals, as well as non-metallic minerals.
This equipment is mainly applied to form a closed-circuit cycle with ball mills in the ore beneficiation plant for pre-classification and inspection classification; it is also used for desliming and dewatering in the process of gravity ore separation and for washing ore in mining operations.
The main frame is manufactured from robust steel plates and channels, ensuring long-term stability and reliable operation even under heavy loads.
Equipped with a spiral mechanism, it effectively separates fine particles from coarse ones in the ore pulp, returning the oversized materials for further grinding.
The spiral blades are lined with replaceable wear-resistant rubber or alloy plates, significantly extending the service life and reducing maintenance costs.
The lifting device allows for easy adjustment of the weir height, enabling precise control over the fineness of the classified products to meet different process requirements.
