ã€China Aluminum Industry Net】 When the roller is rotating, the rotation speed of the roller is generally proportional to the grinding amount. However, when the speed is too high, the parts will be brought to the upper end of the drum by centrifugal force, which reduces the chance of mutual friction, but when they fall, it will cause collisions between the parts and roughen the surface of the parts. At the same time, the rotation speed is also related to the loading amount of the workpiece in the drum. When the loading amount is low, the workpiece falls into the solution, and the collision impact on the workpiece may be less. The rotation speed is usually controlled at about 30r/min. The rotation speed is also related to the diameter of the drum. When the diameter of the drum is larger, the speed of the drum is preferably slower; if the diameter of the drum is smaller, the speed can be increased appropriately.
