Spiral Classifier
Spiral Classifier is widely used in mineral processing plants together with ball mills to form a closed-circuit grinding system. It is mainly used for ore pulp classification, fine material separation, desliming and dehydration in mining and ore washing operations. With simple structure and reliable performance, the spiral classifier is suitable for various ore dressing applications.
- Closed-Circuit Classification – Works with ball mills for ore grinding systems
- Efficient Material Separation – Suitable for ore pulp classification and desliming
- Reliable Operation – Simple structure for stable performance and easy maintenance

Structure of Spiral classifier
The classifier of our company is mainly composed of transmission device, screw body, tank body, lifting mechanism, lower support (bearing bush) and ore discharge valve. The classifier produced by our company adopts advanced technology research and development, featuring simple structure, reliable work, convenient operation, etc.
Working principle of Spiral classifier
When the machine is working, the classifier is based on the principle of different solid particle size and specific gravity, so the settling speed in the liquid is different. Fine ore particles float in the water and overflow, and coarse ore particles sink at the bottom of the tank. A classification equipment that pushes the screw to the upper part to discharge for mechanical classification. It can grade the material and powder grinded out of the mill to filtration, and then screw the coarse material into the mill feed port by using the spiral slice spiral disc to discharge the filtered fine material from the overflow pipe. The base of the machine is made of channel steel and the body is welded with steel plate. The screw shaft’s water head, shaft head, adopt pig iron sleeve, wear-resistant and durable. The lifting device is divided into electric and manual.
Performance characteristics of Fodamon Classifier
1. The screw shaft’s inlet head and shaft head adopt pig iron sleeve, which is reliable in operation and has good washing effect.
2. Fine grading granularity can meet different needs of customers, with high sand return rate.
3. The base is made of channel steel and the body is welded with steel plate, with good quality and high wear resistance.
4. The classifier adopts tile lining, with very low maintenance rate and high durability of vulnerable parts.
