Light roll ball mill is a kind of equipment used for ultra-fine grinding and mixing for laboratory and small batch production, which is also called rolling machine altar. The machine is preferred equipment for scientific research, teaching, experiment and production due to its advantages such as beautiful design, compact structure, easy operation, high efficiency, and uniform granularity. It is widely applied to industries of electronic material, magnetic material, biological medicine, ceramic glaze, metal powder, nonmetallic minerals, new materials and etc. Optimal design of rotating speed is adopted in the machine, where mill jar is dragged to rotate by rubber roller, balls inside the jar make incline flow movement and disperse materials, thus it obtains best effects of grinding. As result, materials are ground into micron powder. Timing control panel is adopted in the machine with controlling functions of pausing and cumulative timing, and you may set working time according to requirement at any time. It saves time and labor, and is easy for operating.
