Vibrating screen is widely used in product classification in mining, building materials, transportation, energy, chemical industry and other industries.
Working principle of circular vibrating screen;
The motor makes the eccentric block of the vibration exciter rotate at high speed through the V-belt. The running eccentric block generates huge centrifugal force, which excites the screen box to generate a certain range of circular motion. The materials on the screen are subjected to the impact force transmitted by the screen box on the inclined screen surface, which generates continuous throwing motion, so that the particles smaller than the screen holes pass through the screen in the process of meeting the screen surface, thus realizing classification.

The material is continuously thrown onto the inclined screen surface along with the screen box, and the material is continuously and evenly delivered to the receiving port.
Working principle of vibrating feeder;
The vibrating feeder uses the centrifugal force generated by the rotation of the eccentric block in the vibrator to make the movable parts such as the screen box and the vibrator make a forced continuous or approximate circular motion. The vibrating feeder consists of a feeding trough, a vibration exciter, a spring bracket and a transmission device. The vibration source of tank vibration feeding is the vibration exciter, which consists of two eccentric shafts (driving shaft and driven shaft) and a pair of gear pairs.
