Single cylinder or multi cylinder and abrasive, so the sample size can be selected at the same time, but at the same time, sample preparation can be mixed with. And the choice of speed cylinder according to different abrasive, frequency conversion technology keys can be achieved. The dry, wet material and sample preparation. Available ball instead of steel bar as abrasive medium. The rotation of the cylinder can be arbitrarily set. Sample grinding parameters of liquid crystal display screens, humanized design. A transparent cover, to observe the operation more convenient.
