For the case of a rotating recessed grinding wheel, finite element computations are modeled as rigid bodies with added gyroscopic effects at critical speeds of rotation. At selected speeds, dynamic outofbalance forces are predicted using rotationdependent terms.

Note that there is an intermesh gap between screw elements. The tolerance between the elements is very tight, but a gap should be visible. A flashlight can be used to confirm visibility and check that the line of light running between the elements remains constant.

The mill shell actually becomes the rotating element of a large low speed synchronous motor. Mill speed is varied by changing the frequency of the current to the motor. The ringmotor can be used to inch and spot the mill for maintenance.

Since the grinding disk and the classifier rotate, the Coriolis and the centrifugal force are taken into account. These are expressed by the two last terms on the right hand side of Eq. 1 . m P is the particle mass, Ω → is the angular velocity, u → P is the particle velocity and r → denotes the position vector.

A critical element to proper grinding is the performance of the carriage and rail system. The BG1000 features precision ground () diameter hardchromed steel rails for increased accuracy when traversing the carriage back and forth for grinding.
