Get Price### Ball Mills

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.

Get Price### D.C. Motor Torque/Speed Curve Tutorial:::Understanding Motor

By substituting equations 3. and 4. (torque and speed, section 2.1) into equation 2. (power, section 1.3 ), we see that the power curves for a D.C. motor with respect to both speed and torque are quadratics, as shown in equations 5. and 6. From these equations, we again find that maximum output power occurs at =, and =repectively.
