Raymond Mill is suitable for producing minerals powder, which is widely used in the metallurgy, building materials, chemical, and mining industry. It can be used for grinding barite, calcite, potash feldspar, talc, marble, ceramic, glass and some other material that Moh's hardness degree is below 7, humidity is in 6%, and non-flammable non-explosive minerals. The final product size is adjustable as required in the range of 100-325 meshes.
Raymond Mill is made up of the Mainframe, Separator, Pipeline System, Air Blower, Jaw Crusher, Hopper Elevator, Electromagnetic Vibrating Feeder, and Electric Control Motor and so on.

Raymond Mill features:
1. Three-dimensional structure
2. land-saving
3. The screen-passing rate can reach to 99%:
4. The transmission is steady and reliable;
5. The transmission device of mainframe adopts airtight gear case and zonal wheel.
6. Centralized control for the electric system, convenient to operate.
Raymond Mill Working principle
The whole machine is collocated with jaw crusher, elevator, hopper, electromagnetic vibrating feeder, main unit, classifier, collector, cloth deduster and high-pressure blower.
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.
The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product.
In the grinding chamber, since the stuff contains moisture to some extent, the heat generated during grinding makes the moisture evaporate; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work in negative pressure, the increased air flow is guided to the deuster and sequentially to the atmosphere after purification.
