pulverizers efficiently reduce aggregate, mineral or coal sample particle sizes using grinding plates, hammermills, or centrifugal impact. grinding mills include ball mills, mortar grinders, and various types of cutting mills and beater mills falls into this category. different models can process a wide range of materials, including tough and vertical mills flexible mills with integrated separator. the vertical mill enables high energy economy, and convinces with low specific wear values. drying of the feed material, grinding, separating, and material transport take place inside the mill. It is thus especially well suited for grinding products with high proportions of wet components.
