Energy Saving Coal Washing Spiral Classifier

 

 

Overview

Spiral classifier, working with ball mill to form close circulation in the concentrating plant, whose classification process depends on the sedimentation velocity of the particles. Its external appearance is a rectangular oblique chute, whose bottom is semi-circular. There is 1 or 2 vertical axles installed in the chute, spiral blades are installed along the axle one after another. With the help of the drive motor on the top, the whole machine can drive the screw shafts to rotate.

 

Application

Spiral classifier is widely used for separating the sand in the ore beneficiation plant to equip with ball mill to form a closed cycle. In the  gravitational concentrating works, spiral classifier is used for classifying the ore and the fine. In the washing ore  works, spiral classifier is used for desliming. And the spiral classifier is used for dehydrating and feeding, too.

 

Basic Structure

The spiral classifier is made up by the several parts, as follows:

1. Chute .Under the chute there is a output hole that used for discharging the ore.

2. The spiral part

3. The driving part

4. The lifting structures of spiral

5. Upper support

6. Ore discharging valve

 

Working Principle

The spiral turns slowly by the motor and reducer, the chute must be installed gradient on the foundation. The obliquity that between the bottom of chute and level is from 15 to 30, in overfall side it forms the deposit pool. The mine slurry comes into deposit pool along the chute side. As a result of mixing by spiral, small grain floats out of liquid surface and discharges from overfall side. The big grain deposits to the bottom of chute and discharged by spiral from the sand discharging hole and comes into the ball mill to grind again.  The size of obliquity will affect flooding granularity. The rotary speed of spiral will affect the flooding size.

Features

1. Can be very convenient to control the content of sand powder and to meet users’ requirements.

2. Spiral classifier has advanced technology, simple process, particularly suitable for large and medium-sized sand making production line.

3. The content of powder with size of 0.00--0.75mm is between 2%-15% and can be adjusted.

4. The quality of powder is easy to control. The adjustment of fine is convenient, flexible and reliable.

5. Tile lining, repair rate is very low.

6. Adopting variable frequency control technology, so operating is more concise.
