Mill (grinding) Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

which the operating pulses of a motor being used in a medium or highspeed region are gradually changed. It is found by the equation below. Usually, the acceleration (deceleration) period (t1) is set at roughly 25% of the positioning periods. For gentle speed changes, the acceleration torque can be kept lower than in startstop operations.

c) Power Factor : 0.75. d) Motor efficiency : 85% . Formula 1 : Pi = (V xI x PF x 1.732) / 1000. Pi = (461 x 34.1 x 0.75 x 1.732) / 1000. Pi = 20.4 kW . Formula 2. Pir = (HP x 0.7457)/Efficiency. Pir = ( 30 x 0.7457) / 0.85. Pir = 19 kW . Formula 3. LOAD = (Pi / Pir) x 100%. LOAD = (20.4/19) x 100%. Output power as a % of rated power = 107.4%
How to calculate motor drive torque for ball screws
(In ball screw terminology, we commonly refer to lead, which is the linear distance the screw moves for every complete rotation, rather than pitch, which is the linear distance between screw threads.) The equation for drive torque: Td = (Fa * P)/(2000 * π * η) demonstrates that torque, T, is directly proportional to the lead of the screw, P.
