The main content of a planetary ball mill and section describes: need a bearing mounted on two large and can be placed horizontal rotary cylinder, the cylinder with the diaphragm plate divided into several compartments, each compartment has a certain shape and contents grinding size. Planetary ball mill grinding body is generally steel balls, steel forging, steel bars, gravel, gravel and balls and the like. In order to prevent wear of the cylinder is fitted with the role of grinding mill lining material in the cylinder wall, when the planetary ball rotation, grinding and centrifugal force generated in the cylinder wall liner surface friction under the action , attached to the inner wall of the cylinder liner surface, together with the cylinder rotation, and taken to a certain height, free fall under gravity, the whereabouts of grinding as projectiles, like the impact of the material at the bottom of the crushed material .
Grinding rise, circular motion is the cycle of falling. In addition, during the rotation of the planetary ball mill grinding body also produces sliding and rolling, thus grinding, grinding action between the liner and the material, the material ground. Due to the feed end of the continuous feeding of new material, so that between the feed and discharge end of the material there is a difference between the material surface can be forced material flow, and drop impact when grinding materials also produce axial thrust forces the flow of materials, in addition to the mill stream Sport also helps the flow of material. Thus, although the mill shell is placed horizontally, but they can slow the flow of material from the feed end to the discharge end, complete the grinding operation.
