Raymond grinder also called 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.

Raymond grinder is a new style powder grinder mill, 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.

Features / Advantages:

  • With a small floor area and good entirety, Raymond mill can operate independently and automatically from piece crushing to product packaging.
  • Powder ground by Raymond grinder can be screened at a rate of above 99%, which other grinders are unable to achieve.
  • 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.
  • .Electricity is central controlled without manual operation in host machine room.
  • Host machine driving unit adopts closed reduction box, which achieves stable transmission and reliable rotation without leakage of oil.
  • 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.

Raymond Grinder Application

Raymond mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. Raymond mill can produce powder from more than 280 kinds of non-flammable and non-explosive mineral materials with Mohs hardness below 7 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum, trona etc. The final size is between 613micron and 440 micron

Working Principle of Raymond Grinder

The working principle is as follows: load the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings go outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded. After being grinded, the stuff is to be routed to the classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding.
