Spiral Classifier Machine for Separating Classifying Mining Gold Copper Silver

Spiral Classifier Product Overview

Spiral classifier is widely used to pre-grading and inspection grading in closed circuits when used in the production flow of metal processing.

According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified.

Waste mud or water for ore sand can be separated from the ores. Spiral classifier’s also usually applied to ore washing, desliming and 

dehydration and so on.

Spiral Classifier Working Principle

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.
