Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.
Laboratory ball mills have been an essential tool in pharmaceutical research and development for quite some time. These versatile instruments play a pivotal role in the grinding, blending, and homogenization of various materials, offering scientists and engineers the means to explore new formulations and optimize processes.
