Raymond mills Specifications Raymond mills have the character of high efficiency, energy-saving, low pollution, high output and good quality. Raymond Grinder/Raymond mill is applicable to the grinding and processing of more than **0 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical, industry and metallurgy, such as barite, calcite, feldspar, talcum, pencil stone, marble, coke, powdered-coal, dolomite, fluorite, active carbon, betonies, ceramiciron ore, granite, iron oxide yellow, gold mine, porcelain clay, plaster, limestone, clay, glass. The fine mess of the finished product can be adjusted from *0 mesh to **5 mesh according to requirement, and the most finest final products will reach ***0 mesh. Raymond mill of Working principle The whole raymond mill machine is collocated with jaw crusher, elevator, hopper, electromagnetic vibrating feeder, main unit, classifier, collector, cloth detester and high-pressure blower. The raymond mill 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.
