Pneumatic Lugged Wafer Butterfly Valve





 

The machine consists of hopper, vibration chamber and coupling and motor. There are eccentric wheel, rubber shaft parts, main shaft bearing and so on. The adjustable eccentric weight can drive to the central line of main shaft through motor. Under the unstable state, it produces centrifugal force that makes raw material from vortex in the sieve. The size of eccentric weight can be regulated in accordance with the different raw materials. The Sieve Machine is suitable for flow operation , it is an ideal equipment for granule which the size proportion is not uniform to separate. It has centrifugal vibration separated layer sieve which is very practical.
