The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact ...

KELK Strain Extensometers. Extensometers are simple, economical sensors attached to rolling mill housings to measure the strain in the housing posts resulting from roll force. Roll force can be derived from these measurements, but due to outside influences, these calculated results can never be as accurate as direct load cell force measurement.
