    The machine (also called Raymond Grinding Mill) is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, ceramics, whose Mohs hardness is below 7 and humidity does not exceeds 6%. They are all non-inflammable and non-explosive stuff. The product size is adjustable as required in the range of 100-325mesh.Now this series have a high ratio in home market. They are popular with the cosmic company, the mineral factory. The powder is extremely fine.

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 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 sorter along the wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the product cyclone collector together with airflow and is expelled from the powder output pipe as product.

In the grinding chamber, since the stuff may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated; 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 under negative pressures, the increased airflow is guided to the deduster anew sequentially to the atmosphere after purification.

1.All of the key parts are made of high-quality steel, and all the wearing parts are made of high-quality wear resistant materials. These both endows the machine with a high wear resistance and stable running.
2.The electric system is controlled by the central processing unit, and the whole process can be working with no man.
3.The finished products have an even distribution in fineness. And the sieving rate can be up to 99%, which other grinder mills cant achieve.
4.The transmission system adopts sealing gear case and belt pulleys, which makes a stable transmission and reliable performance.
5.It is something like a cube, which covers a little area. Besides, it is easy to form a complete set from the material bulk or finished powder.
