In this direction, high-pressure grinding roller (HPGR) mills, developed in the 1980s (e.g., Schönert 1979, 1988), represent a relatively new technique in mineral processing. The HPGR mills yield higher energy efficiency than ball mills, probably because the particles are confined to a certain extent, which can reduce both the energy …
JXSC grinding & classification equipment is the key equipment for crushing materials after they are crushed. The ball mill can process various grinding minerals, non-ferrous metal beneficiation, and new building materials. It is often combined with a spiral classifier to form a closed-circuit ring mill, which has higher fine powder and grinding power.
