spiral classifier

Usage

Widely used in mineral processing plant in match with ball mill, forming a closed-circuit circulation, to grade ore, deslime and dehydrate in gravity mineral processing plant.

Production Presentation

Range of application: High weir single/double spiral, Submerged single/double spiral 4 types of classifier.

Structure: it mainly composed of gearing device, spiral device, channel, elevator device, bottom base (bearing bush) and discharging valve.

Features

Widely used in mineral processing plant in match with ball mill, forming a closed-circuit circulation, to grade ore, deslime and dehydrate in gravity mineral processing plant and grading ore pulp of metal beneficiation flowsheet etc. The equipment has the advantage of simple structure, credible work, convenient operation etc.

Operating Principle

The spiral classifier is a mechanical classifying equipment based on the principle that different size and specific gravity of solid particles, which would have different sedimentation rate in the liquid. The fine ore particle outputs which overflows on the water, the coarse ore particle sinks down to the water. It’s a classifier equipment of which the spiral groove thrust and discharged to the upper to mechanical classify, which can filter the coarse particles from the miller, then input the coarse particles by spiral groove flight, discharge the fine particle from the overflow pipe. The base device used of channel steel, machine body used of steel board connecting by welding. Its waterhead and spindle head used of pig iron set, with the function of wear-resisting and durable, there’s two of power-driven and manual operation of the elevator device.
