  • Choose Right Speed To Improve Ball Mill Grinding

    Ball mill is one of the commonly used equipment in mineral processing equipment. Rotation speed is one of the main parameters in the design and operation of the ball mill. The rotation speed directly determines the movement state of the grinding medium in the barrel and the effect of grinding operation. Too fast or too slow rotation speed will weaken or lose the crushing effect.

  • Attritor Grinding And Dispersing Equipment

    For example, ball mills use large media, normally or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead and horizontal, use smaller media (from 1/64 to 1/8), but run at a very high rpm (roughly 800-1200). High-speed dispersers with no media run even faster (1200-1800) rpm, with tip speeds of 5000-6000 fpm.
