The vibrating screen is widely used in the classification of raw coal in coal mines, fly ash in power plants, 38 pieces of electrical coal, coal gangue and other materials.
Coal vibrating screen is composed of vibration source (vibrator), screen body, screen mesh, damping device, base, etc.
The screen mesh is divided into single layer, double layer and multi-layer, with diversified structures, including polyurethane screen plate, manganese steel punched screen mesh and woven screen mesh. The screen mesh has different apertures of 5-80mm, which can be selected by customers according to their own needs.
Working principle: the screen machine is composed of vibration motor 1. screen body 2. primary damping spring 3. primary damping 4. secondary damping spring 5. base plate.
Rely on the same two vibrating motors to rotate in the opposite direction, so that the screen body will make periodic reciprocating motion along the direction of the exciting force, forcing the materials to make continuous parabolic motion on the screen surface.
The pulverized coal will quickly loosen through the screen, and the debris such as wood chips and fibers will remain on the upper part of the screen, which will be periodically cleaned manually.
After the equipment is powered on, the loader loads the raw materials into the large capacity storage hopper, and the raw materials are put into the horizontal screen barrel through the feeding belt. The rotating screen barrel drives the raw materials to form the artificial sand screening effect of raw materials sliding on the screen mesh surface under the pushing and rolling of the blades in the barrel, The screened finished sand falls on the finished sand belt through the aggregate hopper, and at the same time
