The anti-blocking device, also known as a silo wall vibrator, is used to make theinclined wall of the material hopper, hopper or container vibrate at high frequency.destroying the stable state of the material to eliminate the phenomenon of material archingin the silo and adhesion of material to the silo wall, so that the material can flow smoothlyfrom the hopper, hopper or container. The anti-blocking device has the advantages ofsimple structure, strong anti-blocking ability, low energy consumption, long service lifeand adjustable vibration force. lt is widely used in coal, metallurgy, refractory, medicine.power generation,ports and railway transportation industries.
