3 terms and definitions

The following terms and definitions apply to this standard. 3.1 Gravity screen Robust screening equipment for sieving or washing wet material by gravity and centrifugal force. It is mainly by the feeding device, screen surface, screen box, out Material mouth and stent and other components. 3.2 Curved screen surface Made of stainless steel wedge sieve made of curved sieve surface, gravity curved screen standard screen surface curvature of 50 °.

4 working principle

Wet material at a certain speed evenly overflow from the overflow dam, from the tangential direction of the introduction of the screen surface, the wet material evenly through the screen surface filtration, With the sieve at right angles through the curved sieve surface, small particles and liquid flow into the sieve below the coarse-grained material from the screen surface to go to the sieve Or washing the separation process. ......
