Difficulties in screening rubber powder

Scrap tires after the initial crushing and crushing, into a granular coarse powder, after a small steel mill, and then grinding out of the powder to achieve 60 mesh, 80 mesh fineness. Coarse rubber powder is screened well by linear screen, but the fine powder grinding through the steel is not easy to screen because the rubber powder itself is too fine and elastic. If the traditional linear screen is easy to block the screen, the output of the centrifugal screen is low and the accuracy is not high, choosing a rubber powder sieve with large net output has become a major problem for rubber powder manufacturers.

Rubber powder screening features

In view of the above problems our engineers developed a set of special screening 60 mesh, 80 mesh fine rubber powder airflow screen. The advantage of this device is that:

1. Large output, If 60 mesh fine powder is screened, the output can reach 800 kg/h.

2. Series in front of the cyclone collector, screening and eliminating miscellaneous and unmanned.

3. Closed system, no dust, environmental protection.

4. The finished product is of high precision.

5. Adopt negative pressure suction material, not easy to block the net.

Working principle

The materials ground out of the mill, after negative pressure, are transported to the inlet of the gas flow screen, the material and the air are mixed, and enter the vertical installation of the bucket type, the middle of the screen net, and the wind wheel blades in the center of the screen machine are rotated at high speed and generate enough centrifugal force.The qualified materials that meet the particle size are sprayed through the net, and the fine powder that passes through the net is collected by the cyclone collector. The coarse material that can not pass through the net is shot out from the automatic dregs, so as to achieve the purpose of rapid screening. The entire system is closed and there is no dust,and save manpower.
