what is the allowable vibration limits for impact crushers

Apr 01, 2001 More stringent specifications regarding motor vibration call for maximum velocity levels of 0.1 in./sec on the housing and 1.5 mils of displacement vibration on the shaft. The limits apply to a motor mounted on a seismic mass, and uncoupled or coupled to a piece of equipment in a way that eliminates any vibration in the driven equipment.

Impact Crushers VSIs and HSIs. Impact-style crushers include VSIs, as well as horizontal shaft impactors (HSIs), and are best used with less abrasive rock types, like limestone. These types of machines break apart material by the impacting forces of certain wear parts known as blow bars and impact plates or toggles.. Some operations also use impact-style crushers after they have already ...
