Background

The process of dividing the material to be crushed into different size fractions by one or more layers of screening surface is called screening. The sieving machine is a vibrating sieving mechanical device which utilizes the relative movement of bulk materials and a sieve surface to lead partial particles to penetrate through sieve pores and divide materials such as sand, gravel, broken stone and the like into different grades according to the particle size. The screening process of the screening machine is generally continuous, after screening raw materials are fed onto a screening machine (called a screen for short), materials smaller than the size of the screen holes penetrate through the screen holes and are called undersize products; material larger than the mesh size is continuously discharged from the screening surface and is referred to as oversize product.
