The screening at this time is called prescreening. For sand and gravel processing plants, pre-screening can avoid ineffective crushing of materials, thereby increasing the production capacity of crushing equipment and reducing power consumption. A soil-leakage feeder or a special vibrating screen is an ideal pre-screening equipment. Check sieving
