Raymond mill

Raymond Mill is mainly used to grind non-inflammable and non-explosive materials with Moh’s hardness below 7 and moisture content below 6% such as barite, calcite, potash feldspar,talcum, marble, limestone, ceramic, glass, etc Raymond Mill can be used in mining, chemicalindustry, construction materials, metallurgy and so on. The final products can be adjusted freely from 100 mesh to 425 mesh.

The structure of the main frame is consist of mill, separator, duct system, blower and can equips crushers, elevator, electro-magnetic vibrating feeder ,electric cabinet and so on. Load the stuff for grinding evenly and continuously into the grinding chamber of the mainframe. 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.

Working Principle of Raymond Grinder

Firstly, raw material is crushed by jaw crusher to the size required, then elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. ... more
