Anchor dear be of RMG equipment

As a machine manufacturer of RMG equipment. How does the media behave during the full process.
Dry mixing is at high speed and the torque is pretty low. Whereas the granulating is at low speed with high torque. This assumption is correct ??
If that is the case A Constant Power Transmission on Anchor drive is desirable
Or A Constant Torque with power variable is Desirable ??

Torque is associated with load as load increase torque increase thats y in wetting its increase.n in dry mixing it decreases.In end poin determination torque value is noted
