Vertical Mill

    HRM Vertical Mill applies to grind coal, coke, cement raw material, gypsum, barite, phosphorite, calcite, kaolin and other medium degree hardness solid material. HRM series vertical mill is integrated with crushing, drying, grinding and separating. Process flow is easy. Compared with tube mill, vertical mill has many advantages. High grinding efficiency; Reducing 20-30% electricity consumption; Big drying ability; Material moisture can be 15%; Material in-size is bigger; Degree of product fineness is easier to adjust; Chemical composition is steady; No steel ball impact; No direct touch between metals; Low noise; Low wear; There is separator in mill, no need to match powder concentrator; Small cover area; Grinding rollers can be taken out of the mill; Easy maintain and so on.
