Raymond Mill, manufactured by Shanghai Shibang Mahinery Co., Ltd., is effective closed-circuit high fineness powder manufacturing equipment applicated in small and medium mining, silicate and chemical, building-material, metallurgy, refractory material, pharmaceuticals and lime industry. It is a new style powder grinding machine, which is more advanced than ball grinder and much appreciated in many fields due to its domestic leading level in each technical specification. This product adopts advanced structure of similar products from abroad, and is updated and designed based on large Raymond grinder. Under centrifugal force, grinding roller rolles closely on grinding ring, which shall not affect yield and fineness of ground powder in the case that grinding roller and ring are worn to a certain degree. Grinding roller and Grinding ring enjoy a long update cycle, which eliminates disadvantage of short update cycle for easily damaged parts on centrifugal crusher. In this grinder, pneumatic flow goes circularly through fan--grinding enclosure--cyclone separator—fan. Therefore, dust in this machine is less than that in high speed centrifugal grinder, and operation workshop is relatively clean without environmental contamination.

This grinder Mill is applicable to high fineness powder manufacturing of over 300 nonflammable and non-explosive materials, with Mohs’ scale of hardness no more than Grade 7, and humidity less than 6％, which are widely used in mining, silicate and chemical engineering and building Industry. For example, barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, active floridin, activated carbon, bentonite, kaolin, cement, rock phosphate, gypsum, glass, manganese minerals, titanium minerals, copper minerals, chromium minerals, refractory materials, thermal insulating material, coal tar, coal powder, carbon black, pottery clay, bone powder, titanium dioxide, iron oxide, quartz, etc. Product size can be freely controlled within 80-325 mesh, and in particular, some can be 600 mesh. 1. With a small floor area and good entirety, Raymond grinder can operate independently and automatically from piece crushing to product packaging.
2. Powder ground by Raymond grinder can be screened at a rate of above 99%, which other grinders are unable to achieve.
3. Electromagnetic-vibrating feeder is easily regulated, small in volume and light in weight. It saves oil and electricity, and enjoys convenient maintenance. The adoption of it shall ensure the uniformity of feeding.
4.Electricity is central controlled without manual operation in host machine room.
5. Host machine driving unit adopts closed reduction box, which achieves stable transmission and reliable rotation without leakage of oil.
6. Shovel tool rest for host machine keeps in touch with materiel while rotating. It is composed of two parts, of which bracket may be changed after abrasion through dismounting bolts connected.
