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

　　Fluidized Bed Grinding is the main model of gas flow grinding. It has obvious advantages compared to other crushing equipment, which represents the mainstream direction of gas flow crushing equipment, widely used in pharmaceutical, traditional Chinese medicine, pesticide, chemical, metallurgy. Non-metallic mine, talc, heavy gold stone, kaolin, quartz, graphite, flame retardant materials, advanced materials, ceramics and other dry powder materials.Quartz sand is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractory materials, metallurgy, architecture, chemical, plastic, rubber, abrasive and other industries. Quartz sand is quartz particles formed by quartz stone. It is a raw material that is more difficult to process in non-metal minerals, with strong representative quartz, density 2.6 g / cm3, Moh's hardness is 6.5-7.5, which is naturally high hard wear resistant material in mineral pulverization. Quartz sand crushing requires low iron, good granular shape, concentrated particle size, small fine powder, no dust, is a non-metal mineral.

　　Shandong Erpai quartz ultra-micro gas flow pulverizer is compressed air, filtered, dried, forms an ultrasound air flow through nozzle In the comminution, the material is fluidized, and the accelerated material is combined in several nozzles, which produces severe collisions, friction, shear, and ultrafine pulverization of the particles. After the pulverized material is conveyed into the impeller grading area, under the action of the graded wheel effort and fan effort, the coarse powder is separated, and the coarse powder returns to the crushing chamber according to its own gravity, and the qualified fine powder is Airflow enters the cyclone, fine dust is collected by the bag dust collector, and the purified gas is discharged from the air.

　　Characteristics of Shandong Erpa Shi Shi Super Micro - gas current pulverizer:

　　(1) The machine is a fluidized bed and a high-precision vertical turbo unit The latest combination.

　　(2) High efficiency: Protective Utilization of Spraying, greatly increases pulverization efficiency.

　　(3) Wear Small: "Fluidized Bed + Vertical Turbine Grading Machine" can be high purity, ultra-narrow processing ultrafine powder, avoiding "spray + vertical grading machine" The wear of the pulverized portion, and the wear of the "fluidized bed + horizontal grading machine". Under the same material, the equipment is easy to damageThe service life of the part is equivalent to 8 times the international similar product.

　　(4) High grading accuracy: stable, complete hierarchical flow field, and special sealing measures, reliably prevent the leakage of the crude particles from circulating in the fluidized bed formation. The qualified product particle size D97 = 2-74 μm is guaranteed.

　　(5) Those smashing: unique grading flow field, reducing the gas solid concentration of the graded area, avoiding pulverizing.

　　(6) variable combined structure: can be used one by one, which can be used as a pulverization charter, and can also be a separate classifier.

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

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

　　(9) The device has particle morphological control technology to maintain material properties.

　　The Elfi fluidized bed airflow pulverizer is also widely used in chemical, abrasive, ceramics, environmental protection, new materials, new energy, non-metallic mine, medical food, powder metallurgy, battery materials, etc. , High purity and ultrafine pulverized grading segment of high hardness dry materials.

　　Excellent refinement, win! In order to ensure the "zero-defect, continuous improvement" quality improvement and effective development, Shandong ALPA Powder Technology Co., Ltd. Quality Management Committee actively explores the management of new models, receiving the study of 8D working methods in recent hours, and combines enterprises Operation status, initially formed organic combination, comprehensive quality control system and successful practice, effectively improved the company's quality risk prevention and control ability, in order to promote the high-quality development of enterprises to build a solid foundation.
