half of the screen mesh size, the half-size factor will exceed unity and vice versa. K2 2P F(0.5h) 0.2 (4-5) The oversize factor K3 A screen can handle a greater tonnage of feed material that contains large quantities of oversize material because this material passes directly over the screen and need not be transmitted through the mesh.
Screening is a separation process that classifies materials according to their particle size and is a key unit for mineral processing and utilization. Recently, vibrating flip-flow screens (VFFSs) characterized by large vibration intensity of the screen surface and high efficiency for sticky fine particles have been widely applied.
Classification, size limitation of crusher feed, dewatering, slime cleaning, solid recovery, washing and etc. are some of the main utilization purposes of screening in mineral processing plants (Mular et al., 2002). Screening is widely applied in ore preparation and many other areas (food, textile, etc.).
The vibrating screen has absolute advantages in the sorting equipment due to its simple structure, reliable operation and large processing capacity.
