ISO9001 & CE certificated Calcium carbonate Roller Mill
HGM Series ring roller mill is a dry ring roller mill ultrafine powder milling equipment, is the fineness of my strengths and weaknesses of domestic and foreign companies with a variety of roller mill equipment and innovation developed from the use of fluid mechanics, can smash up to 3 ~ 35um, with good performance, high efficiency, small footprint, easy installation features, product size indicators, stable performance. 2. Application and Characteristics It is widely used in conventional grinding crushed materials, such as kaolin, limestone, calcite, talcum, graphite and other humidity less than 8%, Mohs hardness of 6 or less superfine processing of nonflammable materials, is ideal nonmetallic mineral powder materials processing equipment. The machine characteristics as following: 1, compared with Raymond mill, a jet mill under the same dynamic conditions of high productivity more than doubled, the grinding wheel to grind the material ssure increased by 30% to 40% under the influence of high pressure centrifugal force. 2, output capacity: When crushed calcium carbonate, when the fineness of 10um, hourly output of up to 1 ton. 3, the product fineness index is good: D97 = 3 ~ 35um, achieve fineness index fluidized bed jet mill. 4, grading impeller mounted variable speed device do not stop to adjust the granularity of the product, and fines can all recycle, do not pollute the environment.

FAQ 1. What material you want to grind, is it dry, what is the size of feed material ? 2. What capacity you expect ? (kg/h) 3. What mesh or mm or micron(size) of the powder you want? 4. What voltage you want? For example, 380V 50hz 3p; 440V 60Hz,3p; 220V...etc. (We only provide 3P, because our machines are all for industrial use,not for family.)
