Raymond Mill

The Raymond mill is used in grinding the non-flammable and non-explosive stuff which has the Moh's hardness below 7, humidity less than 6%. Its feed size is 20-30mm and production capacity is 1.2-11T/h. As the same for other grinidng equipment, The Raymond mill has many applications, such as:limestone, gypsum, barite, carbonate calcium, marble, feldspar, dolomite, granite, kaolin, bentonite, bauxite, etc.

Raymond mill Structure

Raymond mill structure mainly by the host, analysis machine, blower, finished cyclone, plumbing fixtures, electrical and other components as following picture.Raymond mill structure also includes other devices:

Raymond mill Structure
  • Powder delivery device is in Raymond mill structure, ore powder material handling equipment needs from the storage point to the crushing mill to the classifier to the next level classifier arrow to vault
  • Feeding device is a device in a storage bin discharge port can even unloading material contact, and then fed to the next device, the feeder is Raymond mill structure essential equipment
  • Collecting equipment is mainly used to collect high-quality powder grind.

Raymond Mill Working Principle

There are three pneumatic roller is pressed against the disc with an annular groove, the motor drive system driven by the disc at a constant rotational speed (20-30r / min). Friction caused by the grinding action between the material and the roller, the roller at work to make itself around the axis of rotation. By a hydraulic cylinder connected to the mill base drive rod mill three triangular internal corner of the tension frame, so that downward pressure roller, roller supported on the rolling bearing means hingedly connected to the pressure frame, there feed chute into the material (size 80-100mm), ground to 80% through 200 mesh fineness was millstone around the annular inlet pass into the waste heat blew through the upper part class is graded, coarse fall back in the disc grinding, powder through the outlet into the dust collector for collecting the finished product
