Raymond Grinder

The machine is suitable for grinding more than 280 kinds of non-inflammable and non-explosive materials with the hardness below scale 9.3 of moh’s and the moisture content below 6%, such as barite, limestone, kaolin, ceram and slags, etc, in the trades of mining, metallurgy, chemical engineering and building material for high fine powder generating and processing. The product size is adjustable on required in the range of 100-325 meshes.
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 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.
