What are the working steps and core technologies of air jet mill? Umico Powder Machinery

With its unique working principle, the air flow pulverizer can process superfine powders of various materials in a dry, high-purity and low-temperature manner, and is widely used in industries such as chemical industry, mining industry, abrasives, battery materials, refractories, non-metallic minerals, metallurgy, building materials, pharmacy, food, pesticides, feed, new materials, environmental protection, etc., as well as superfine crushing, breaking and particle shaping of various dry powder materials

jet mill is one of the most important superfine crushing equipment, among which fluidized bed jet mill has the advantages of low energy consumption, small wear and high classification accuracy, and is most widely used in the current superfine crushing equipment< Br/>Working principle and characteristics of fluidized bed air flow pulverizer< Br/>< Br/>(3) The crushed materials move together with the rising air flow to a certain height at the upper part of the grinding chamber, the coarse particles fall back to the lower part of the grinding chamber along the wall of the grinding chamber under the action of gravity, and the fine powders move together with the air flow to the turbine classifier at the upper part< Br/>(4) In the flow field generated by the high-speed turbine, the coarse particles are thrown near the cylinder wall under the centrifugal force, and fall back to the lower part of the grinding chamber together with the stalled coarse powder for crushing< Br/>(5) The fine powder meeting the fineness requirements is transported to the cyclone separator through the grading sheet flow channel and the exhaust pipe for product collection. A small amount of fine powder is further separated from the gas and solid by the bag filter, and the purified air is discharged from the fan by the induced draft fan< Br/>(6) The connecting pipe can keep the pressure of the silo consistent with that of the crushing chamber< Br/>(7) The upper and lower material levels of the silo are fed by the star valve automatically controlled by the precision material level sensor, and the material level of the crushing chamber is automatically controlled by the dynamic current transmitter on the classifier to control the feeding speed of the screw feeder, so that the crushing is always in the best state< Br/>The core R&D technologies possessed by the air flow crusher include: full utilization technology of jet energy, high efficiency classification, strict control over crushing technology, reliable sealing and leak free technology, large particle control technology, complete, stable and smooth system design technology, constant gas-solid concentration ratio technology in the crushing chamber, ultra-fine powder collection and dust removal and flue gas treatment technology, ultra-fine crushing particle shape control technology, etc
