Raymond mill is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements. 

Raymond Mill Working Principle:

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 deduster and sequentially to the atmosphere after purification.

Structure 

1, Raymond three-dimensional structure, small footprint, complete and strong, expect the finished powder independent self-contained production system from the block.

2, refined powder fineness of uniform through screening rate of 99 percent, which is difficult to have other milling equipment.

3, the host mill adopts airtight gearing and pulley gear box, transmission smooth, reliable operation.

4, Raymond important components are used quality steel, wear-resistant parts are made of high-performance wear-resistant materials, machine wear, reliable operation.

5, the electrical system with centralized control, milling plant can achieve the basic unmanned operation, and easy maintenance.
