Product Details

Main Application of Raymond Mill(Raymond Grinder):

Raymond Grinder(Raymond Mill) is used to grind barite, calcite, potash feldspar, talcum, marble, limestone, ceram and slag below scale 7 of Moth’s hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the traded of mining, building material, chemical engineering and metallurgy for power generation and processing. The product size is adjustable on required in the range of 100-325 meshes.

Functional Process of Raymond Grinder(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.
