Detailed Descriptions of  Grinding Mill Raymond mill is used for ultra-fine powder processing of 280 materials, with the Moth's hardness of 9.3 below and humidity of 6% below, in the works of non-flammable mine, chemical industry and building materials, etc. The materials include barite, calcite, potash feldspar, pencil stone, marble, dolomite, fluorite, limestone, active carbon, bentonite, etc. The particle size of finished product can be adjusted from 80-325 meshed. And it can reach 2000 meshed at the maximum.

Grinding Mill Operating principle:The whole machine is collocated with jaw crusher, elevator, hopper, electromagnetic vibrating feeder, main unit, classifier, collector, cloth deduster and high-pressure blower.The working principle is as follows: 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 go 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 classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product.In the grinding chamber, since the stuff contains moisture to some extent, the heat generated during grinding makes the moisture evaporate; 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 in negative pressure, the increased air flow is guided to the deuster and sequentially to the atmosphere after purification.
