rotary bearings are common components in motion systems. they're used in gearboxes motors pulleys fans pumps—virtually any time a shaft is rotating rotary bearings are there to reduce friction and support radial or axial loads. the classifiion of rotary bearings begins with the type of bearing that supports the load—ball or roller.
20191029&ensp·&enspthe grinding efficiency of semi autogenous milling or ball milling depends on the tumbling motion of the total charge within the mill. utilization of this tumbling motion for efficient breakage of particles depends on the conditions inside the mill. however any kind of monitoring device to measure the conditions inside the mill shell during
