Raymond Mill(Raymond Grinder) is relevant towards the grinding and processing of more than 280 types of non-flammable and non-explosive materials with hardness lower than 7 and humidity lower than 6% in mining, construction ,chemical industry and metallurgy, such as barite, calcite, feldspar,talcum, marble, limestone, clay, glass. The fineness from the finished product could be adjusted from 100 mesh to 325 mesh according to specific requirements of clients.

Working Principle of Raymond Mill:
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.

Raymond Mill Structural Characteristics:
1.The machine adopts electromagnetic vibrating feeder, which ensures even and regular feeding.Raymond mill is easy to adjust, small in dimension, light in weight, with lower oil and power consumption and easy to maintain.
2.The transmission device of the main unit is equipped with an in depth gearbox which ensures its smooth transmission and reliable operation. Attendance of operater is not required within the mill operating room because the adoption of advanced central control console switch.
3.The complete raymond grinder is of a standing structure. Raymond mill features small occupying space and strong integration capacity. Raymond mill can take shape a completely independent production system from the lump materials , crushing to finished powder and packaging.
4.Every one of the finished particles use a good uniformity of fineness, with passing screen rate as high as 98%. This is what other machine cannot reach.
