What is a pressure screen? Another online method is to screen the processing capacity. By reducing the thickened area at the bottom of the screen, the passing volume of the overall screen frame is increased (the heavy slag at the bottom of the screen has poor fluidity, and the area of the screen seam is seriously blocked). The side effect of this is that the processing load of the pressure screen system increases in the rear part, and it is necessary to optimize the processing capacity according to the slag-forming effect of the pressure screen two, three and the processing capacity. In order to alleviate the problem of heavy slag, many rotors are designed in a spiral or approximate spiral upward space shape, and an upward flow is formed during the rotation process of the rotor’s rotation inclination to partially offset the bottom enrichment effect.
