Description and Advantages of Classifier:

The classifier is widely used in the concentrator and make up a closed-loop with ball mill. Ore spiral classifier can also be used to grade ore and fine mud in gravity concentrator, and used for desliming, dehydration, etc. This classifier has the following features: simple structure, reliable performance, easy operation, etc.

Main Features and Functions of Classifier:

  1. 1 Can be very convenient to control the content of sand powder and to meet users' requirements.
  2. 2 Spiral classifier has advanced technology, simple process, particularly suitable for large and medium-sized sand making production line.
  3. 3 The content of powder with size of 0.00--0.75 mm is between 2%-15% and can be adjusted.

Working Process:

The principle of spiral classifier is that different sizes of crushers have different weights, so their sedimentation rates are also different. In the working process, fine ore grains float on the surface of water, and rough grains sink on the bottom of the cell.

Screw grader can classify materials from mill, and then bring the rough grains to the entrance mouth of the mill with the help of flights, and discharge the fine ore grins through pipe. The pedestal spiral classifier is made of box iron.

The body is made of welding steel plates, and faucet and spindle nose of screw shaft are made of pig iron set which is durable. The take-up sets include two types: power-driven and manual operation.
