Vibrating Feeder can feed massive and granular materials into next machine from storage bin uniformly and continuously in production line . It can feed stone to crusher continuously and uniformly and also can do coarse screening work in stone crushing plant. It is widely used in crushing and screening plant in metallurgy, coal mine, mineral processing, building materials, chemical industry, abrasives and other industries, It is stable vibration , reliable work , long using lifetime, also is easy to adjust excited force and control the feeding speed and feeding capacity easily . It is low noise , less power consumption, easy to adjust , no material flushing , also with simple structure, reliable operation, easy to install , light weight , small volume and easy to maintenance and widely used in different industry. Vibrating Feeder is used to feed big material to primary or secondary crushing machine continuously and uniformly , it is with vibration type feeder and linear feeder. This machine is with double eccentric shaft vibration block to make sure the machine can stand the impact by big stone, also with large processing capacity. It can feed stone to crusher continuously and uniformly and also can do coarse screening work in stone crushing plant to avoid crusher stop because of uneven feeding and prolonging the machine using life.
