Raymond mill is classical and mature type with many years’ practice and unceasing improvement, whose frame is more and more perfect, and has the advantage of high efficiency, low energy consumption, small occupation area, less investment and little pollution. However, along with the advantages, there are some disadvantages with the development of the produce requires which is inevitable. High-pressure suspension mill, as an updated version of Raymond mill, should be the day. Advantage
High-pressure suspension mill of Great Wall Heavy Industry Company is a new type of patented products developed themselves, combining many years’ physical truth and demands of industrial development, which creates a new era of international industrial milling with high efficiency and low energy consumption. Compared with general Raymond mill, High-pressure suspension mill has following features:
1. Unique design. The capacity increases 10-30% at the same power by designing a pressure device in the main milling cavity.
2. High adaptation of material, which can mill material at 9.3 in Moh’s scale (Raymond mill at 7).
3. Wide range of output granularity. The output size of High-pressure suspension mill is from 0.95mm to 0.013mm (30 meshes to 425 meshes), while the Raymond mill is 30 meshes to 325meshes.
4. Low electricity consumption. The electricity is adopted centralized control, which is easy to adjust. Working principle
High-pressure suspension mill has the same working principle as Raymond Mill, but its grinding device is fixed with 1000 – 1500 kg pressure springs. When the machine works, the grinding roller, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of Raymond mill given an identical condition and its output may increase 20% to 30%;When the grinding roller and grinding ring reach a certain degree of abrasion by adjusting the length of high-pressure springs to…
