kiln torque derivation against motor power?

Dear All


can any body share the sceintific derivation of torque (formula) against the motor power.

1.) with incrase matrial stickness torque in crease and vice versa  ( any derivation of torque with kiln axis and matrial angle)

In fact the kiln torque effectet by many things  as follow

1- clinker  visocisty  if the material sticky  it will be adhisive to the kiln linning and go up with kiln rotation diriction more than the less sticky material  in this case the kiln motor torque is go up due to the motor make more effort to push the sticky material to up.

2-If burning zone is high temp. torque also go up  in this case l.P will be more that is why ?

3- if kiln speed (less) no match kiln feed and kiln load the torque go up with low speed and high feed and vice versa.

4- is the kiln has heavy coating alsoo you will face high kiln torque

power= torque * angular velocity

angular velocity = 2pi rotational velocity

so torque = powe/ 2pi rpm
