Optimization of mill performance by using
The mill filling should be measured at a minimum of 3 points along the mill. Excess of slurry could also be estimated. To get rid of pulp and rocks in the charge, a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining.
Rolling of Steel in small and medium sized Rolling Mills ...
Torque is the measure of the force applied to the rolls to produce rotational motion while power is applied to a rolling mill by applying a torque to the rolls and by means of work piece tension. In a rolling mill the power is spent principally in the four ways namely (i) the energy needed to deform the steel, (ii) the energy needed to overcome ...
