spiral classifier introduction:

Our spiral classifiers/screw classifier are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydra high efficiency spiral classifier ting in washing. Advantages are simple structure, reliable working condition and convenient operation.the screw classifier used with the ball mill usually in the mineral ore beneficiation plant.

spiral classifier working principle:

According to the principle that different grains are with different specific gravity and sedimentation rate in the liquid, the fine ore flows in the water and the coarse ore sinks in the bottom. The classifier that has machine grading by discharging from the top can filtrate the materials and send coarse materials to the feeding mouth and discharge the fine material from the pipe. The seat of the machine adopts channel steel and body adopts armor plate and the spiral axle adopts wrought iron, so it’s durable. The lifting equipments have two types, by electricity and hand.

spiral  classifier application:

1.Separation of fine particles and liquid from coarse particles

2.Separation of light particles from heavy particles

3.Separation of the particles into a number of products graded according to size

4.Separation of liquid from solid particles

Main features of spiral classifier:

1.Adjustable weirs

2.Sealed, submerged bearing

3.Optional automatic lubrication system

4.Rigid tank and substructure

5.Wide choice of tank design

6.Overflow collection box

7.Wide range of industries serviced

8.Single spiral range from 300 mm to 2 200 mm

9.Duplex spiral models 1 500 mm and 2 200 mm

Main benefits of screw classifier:

1.Energy saving

2.Heavy duty, rugged construction

3.Powerful self-contained spiral lifting device

4.Continuous spiral raking

5.Optimal particle size range 800 to 75 microns.
