Processing effect of fluidized bed jet mill in different raw materials

Fluidized bed jet mill is an advanced pulverizer of zui among current jet mill types, which can meet the requirements of raw material processing with Mohs hardness of 1 to 10, and the particle size of finished products can be freely adjusted from 1 to 74 microns. Therefore, the fluidized bed jet mill has a wide range of applications, including chemical industry, mining, abrasives, battery materials, refractories, non-metallic minerals, metallurgy, building materials, manufacturing, food, pesticide, feed, new materials, environmental protection and other industries, as well as superfine crushing, breaking and particle shaping of dry powder materials. The following is about the processing effect of fluidized bed jet mill in different raw materials provided by Qingdao Youmingke Powder Machinery Co., Ltd

quartz: ultrafine quartz powder is prepared by fluidized bed jet mill, and d95=10 mu can be obtained in cyclone separator and pulse bag filter respectively; M and d97=6 mu; M Two products< Br/>Zirconia: Zirconia can be treated with fluidized bed jet mill to obtain uniform and stable quality, high purity and superfine, and d50< 1μ M of zirconia powder< Br/>Wollastonite: high aspect ratio wollastonite is prepared by fluidized bed jet mill, and the average aspect ratio of wollastonite particles is 4~6 mu; When m, it can reach 17:1~20:1, and the average equal volume diameter exceeds 6 mu; After m, the average length diameter ratio changes little, but the average equal volume diameter increases greatly, and the average equal volume diameter is less than 4 mu; M, the average length diameter ratio decreases sharply< Br/>Ceria: superfine ceria is prepared in dry state by fluidized bed jet mill, and the particle size of the product ranges from 1 to 5 mu; m. Moreover, the output is the highest. The most ideal process parameter matching is that the acceleration distance is 85 mm, the crushing pressure is 0.85 MPa, the classifier speed is 1050 r/min, and the output can reach 53 kg/h< Br/>Molybdenum powder: ordinary molybdenum powder is treated by micro fluidized-bed jet mill. After treatment, the loose density and tamping density of molybdenum powder are greatly increased, the particle size distribution is narrowed, d50 is significantly reduced, the particle morphology is uniform, and the aggregates are all opened; The Fechsler particle size of molybdenum powder can be effectively adjusted within a certain range by properly adjusting the rotating speed of the classifier< Br/>Nanometer zinc oxide: With the airflow pulverization modification process, stearic acid as the modifier, the nano zinc oxide is de agglomerated and surface modified. The particle size of the modified nano zinc oxide is 292.6 nm, and the effect of disaggregation is obvious< Br/>Talc powder: air flow pulverization technology is used to prepare talc powder micro powder. The superfine talc powder shows great mechanochemical effect. Its microcrystalline size ranges from 147.69 to 353.72 nm, and the lattice strain ranges from 0.08 to 0.2< Br/>Silica: the fluidized bed air flow pulverizer is used to treat the silica. After crushing, the particle size of the silica decreases and the mechanochemical effect occurs simultaneously. The microcrystalline size ranges from 22.71 nm to 35.54 nm, and the lattice strain ranges from 0.024 nm to 0.038 nm< Br/>Tourmaline powder: the fluidized-bed air flow pulverizer is used to superfine pulverize tourmaline powder. When the nozzle diameter is 13mm and the speed of the grading wheel is 3900r/min, d50=3.390&mu can be obtained from cyclone and bag collection respectively; M and d50=1.961μ M of tourmaline powder< Br/>Straw: the average fiber length of 60 mu can be obtained by separating the fiber components from the steam treated straw with high moisture content using a fluidized bed jet mill; The yield of superfine milled product of m is 78%, which is 2.79 times of that of untreated straw< Br/>Pearl powder: Pearl powder and nacreous layer powder are prepared by fluidized bed jet mill. The air pressure is 0.8Mpa, the feeding speed is 45kg/h, and the classifier speed is 8000rpm. The fineness and output of the pearl powder are the best< Br/>Qingdao Youmingke is the source manufacturer specializing in the production of fluidized bed jet mill, and is committed to consulting, research and development, manufacturing, sales, commissioning, maintenance and other services of jet mill.
