Analysis of principles and characteristics of quartz stone super-gas flow pulverizer

　　Quartz sand (nature: silicate mineral) is an important industrial mineral raw material, widely used in glass, casting, ceramic and refractory materials, metallurgy, construction, chemical, plastic (structure: synthetic resin) , Plasticizer, stabilizer, color material), rubber (Rubber), abrasive and other industries. Airflow pulverizer and cyclone separator, dust collector, and airplane set into a set of pulverization systems. The main applicable pulverization mechanism determines its scope, high finished product, typical materials are: super hard diamond, silicon carbide, metal powder, etc. Quartz sand is quartz particles formed by quartz stone. It is a non-metal mineral raw material that has strong representative quartz, density (unit: g / cm3 or kg / m3) 2.6g / cm3, Hardness, 6.5-7.5, and Hardness, and Hardness 6.5-7.5. Natural high hard wear resistance (WEAR RESITANT MATERIAL). Quartz sand pulverity requires low iron, good particle shape, concentrated in particle size, small powder, no dust (morphology: solid particles) flying, is a non-metallic mineral is more difficult to processed. The quartz stone ultra-micro gas flow pulverizer is that the compressed air is frozen, filtered, dried, and the nozzle forms a supersonic airflow into the pulverizing chamber, so that the material is fluidized, the accelerated material in several nozzles in the injection air flow point convergence A severe collision, friction, cutting, and ultrafine pulverization of the particles. After the crushing material is conveyed to the impeller (the rotation of the moving leaves), the separation of coarse powder is achieved under the action of the grading wheel effort and the drapent fan. Self-gravity returning the crushing room continues to smash, qualified fine powder into the cyclone collector with the air flow, the fine dust is collected by the bag dust collector, and the purified gas is discharged from the air.

　　Characteristics of Quartz Shichang Ultra-Microdynamic Crushers:

　　(1) The machine is the latest combination of fluidized bed and high-precision vertical turbine classifier.

　　(2) Efficient (effectiency) High: The full use of jet flow can greatly increase the pulverization efficiency.

　　(3) Small wear:; fluidized bed + vertical turbine classifier; can be high purity, ultra-narrow processing ultrafine powder, avoided; for spray + vertical grading machine; wear, and fluidization Bed + horizontal grading machine; the wear of the grading part. Under the same material, the service life of equipment is easy to load (LIFETIME) is equivalent to 8 times that of international similar products.

　　(4) Hierarchical accuracy (accuracy) High: stability (explanation: stable stability; no change), complete grading flow field and special sealing measures (refer to problems), reliably prevent leakage of crude particles Turbine classifier and fluidized bed formation internal circulation, ensuring qualified product particle size D97 = 2-74 μm.

　　(5) Small crush: unique grading flow field, reducing the gas solid concentration of the grading area, avoiding pulverizing.

　　(6) Variable combined structure: can be used one by one, which can be used as a pulverized grade machine, and can be a separate classifier.

　　(7) Fully closed negative pressure operation, no dust pollution, dust removal rate of 99.9% or more.

　　(8) Equipment operation is convenient, unpacking is fast, and noise is small.

　　(9) The equipment has particle morphology control technology to maintain material properties.

　　Fluidized bed airflow pulverizer is also widely used in chemical, abrasive, ceramics (raw materials: non-metallic minerals), environmental protection, new materials, new energy, non-metallic mine, medical food, powder metallurgy (content: extraction from ore Metal or metallic compounds), low temperature, high purity, and Hardness segmentation segments of dry materials such as battery materials.
