China High Pressure Suspension Powder Grinder

Product fineness :30~425 mesh high capacite: 1t/h-20t/h China High pressure suspension powder grinder is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Mohs's hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, Kalium ore, pumice, etc., totally more than 100 kinds of materials. China High pressure suspension powder grinder is  manufactured by Shanghai Clirik Machinery Co., Ltd.,which  is effective closed-circuit high fineness powder manufacturing equipment, which is applicated in small and medium mining, silicate and chemical, building-material, metallurgy, refractory material, pharmaceuticals and lime industry. It is a new style powder grinding machine, which is more advanced than ball grinder and much appreciated in many fields due to its domestic leading level in each technical specification. This product adopts advanced structure of similar products from abroad, and is updated and designed based on large China High pressure suspension powder grinder. Under centrifugal force, grinding roller rollers closely on grinding ring, which shall not affect yield and fineness of ground powder in the case that grinding roller and ring are worn to a certain degree. Grinding roller and grinding ring enjoy a long update cycle, which eliminates disadvantage of short update cycle for easily damaged parts on centrifugal crusher. In this grinder, pneumatic flow goes circularly through fan--grinding enclosure--cyclone separator—fan. Therefore, dust in this machine is less than that in high speed centrifugal grinder, and operation workshop is relatively clean without environmental contamination.     Working principle of  China High pressure suspension powder grinder:   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.
