Product Description

Mineral Ore Beneficiation Plant Spiral Classifier For Ore Pulp With Ball Mill 

Spiral classifier is one of the equipment of mineral processing, spiral classifier with the help of the specific gravity of solid particles, so in the liquid precipitation speed is different principle, a kind of equipment for mechanical classification. It can filter the grinding material and powder level in the mill, and then screw the coarse material into the feed port of the mill with spiral sheet and discharge the filtered fine material from the overflow pipe. The spiral classifier is referred to as the classifier. There are four classifiers: high weir single helix and double helix, sunken single helix and double helix classifiers. The spiral classifier is widely used in the concentrator and the ball mill into a closed-circuit cycle split shunt ore sand, or used in the gravity concentrator to classify ore sand and fine mud, and the metal beneficiation process to carry out particle size classification of pulp, and the desliming, dehydration and other operations in the ore washing operation. The machine has the characteristics of simple structure, reliable work and convenient operation.

Spiral classifier working principle :
* Spiral classifier is mainly composed of transmission device, spiral body, groove body, lifting mechanism, lower support and ore discharge valve. The spiral classifier is widely used in the grinding circuit of beneficiation as the pre-classification and inspect classification machine, and also in the ore washing and desilting operation. It has advantage of simple structure, reliable running, easy operation and so on.
* The specific gravity of solids differs due to their different sizes, so does their sedimentation rates. Therefore, the light and fine particles float above the surface and overflow from the overflow edge. Then they flow into the next working procedure of ore dressing. The heavy and thick particles sink into the bottom of the water tank and become return sand which is transported by the spirals to the ore discharge mouth for discharge. The body seat is made from the channel steel while the body is welded by steel plate. The water inlet head and the shaft head of the spiral shaft are covered by raw iron, which is wear-resisting and durable. And the lifting device can be controlled both electronically and manually.

Spiral classifier features:
1. Mixing impeller, long life.

2. Steel frame, strong and durable.

3. Lifting device, efficient operation.

4. Famous brand motor, strong power.

5. Assemble blades with patience and care.

6. Add protective paint to prevent corrosion and rust.

7. Compact structure and stable performance.

8. Strong welding and smooth grinding.
