This is the ratio of the maximum resistance of the LRS to the minimum resistance before the short is placed in position. The short is placed in position with a shorting contractor. A good turndown ratio will limit the starting torque of the motor to an acceptable value. A good turndown ratio for a 5mW LRS is a 100 or more.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

There is a large gap between the tip speed and power intensity of the lowspeed vertical mills and the highspeed horizontal mills. The VXP mill bridges the gap between highspeed and lowspeed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.
