Dec 01 2006nbsp018332the grinding curve is the product size as a function of feedrate for a fixed feed size it is proposed that for each new milling condition in this case a change in the percentage of ball scats in a mill the peak in the grinding curve must be sought and that must be
Speed torque curve for hammer mill hammer crusher is a high speed rolling hammer and material collision can be used for wet and dry two kinds of broken situation lm series vertical mill is an advanced grinding machine which integrated with drying milling grading and transporting it is the high standard mill which can
Power torque 215 speed 215 2 the power varies in the constant torque speed range and the torque varies in the speed range with constant power the operator must keep the process demand for power and torque below these constraints eg by adjusting mill speed or charge level while still operating in an efficient manner
All has started about 50 years ago with mill diameters less than 20 feet driven by fix speed synchronous or wound rotor motors with the power of about 2 mw around 10 years later the mill sizes increased but the necessary torque could not be transmitted by one pinion therefore dual pinion solutions were developed to power the mills
Made for optimal grinding pinion mill drives are widely used in the mining industry to grind materials to a requested size if the equipment is operating at optimum efficiency this has positive impact on production and operating economics drive solutions are needed for speed and torque control
May 01 2012nbsp018332figure 1 the torque curve and power curve for a constanttorque spindle figure 2 shows the torque and power curves for a spindle motor with constant torque followed by constant power this kind of design is more common for spindles intended for use in the lower speed range and typically the torque is higher
Etap only simulates the torque vs speed as a curve best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve the initial torque to start rotation will most likely be over 100 or rated torque how much depends on the design of the mill
