Working principle and equipment characteristics of airflow pulverizer

　　In 2019, my country's airflow milling market, the demand for medical sectors is the largest, reaching 27%; next is the field of new materials and chemical industry, demand proportion is 11% and 10%; biological, non-metallic The needs of mine and equipment manufacturing are between 5% and 7%; the demand in new energy and food sector is between 4% -5%; other areas are all over 3%. Pharmaceutical, new materials, and chemical industry are an important downstream application market for gas flow grinding in my country.

　　Today, Shandong Erfai powder summarizes the working principle and equipment characteristics of gas flow crusher:

　　Working principle of airflow pulverizer:

　　Compressed air is filtered After jetting the pulverizing cavity at high speed of the Lavar nozzle, the belt is repeatedly collided with the intersection of the high-pressure gas stream, friction and pulverizing, and the crude thick mixture reaches the grading area under the action of a negative pressure fan, a hierarchical turbine at high speed Under the generated power, the crude material is separated, and the material to which the particle size required to enter the cyclone and the dust collector are collected by the grading wheel, and the crude particles drops to the pulverizing region to continue pulverizing.

　　Airflow pulverizer feature:

　　● Dry pulverization of various materials suitable for the following materials, especially suitable for high hardness, high purity and High value-of-value material.

　　● Small pulverization, good particle shape, narrow particle size distribution and no large particles, product particle size D97: 5-75 microns are adjusted.● During the pulverization process, due to the sharp expansion of the airflow, the airflow temperature is lowered, particularly suitable for thermal sensitivity, low melting point, sugar and volatile material.

　　● The material collides with each other, which is different from the mechanical pulverizer to the impact of the material or a hammer, so that the equipment is not worn, and the product is purity.

　　● Can be used in series with a multi-stage classifier, and produce a product of multiple particle size sections at a time.

　　● The equipment is compact, the disassembly and cleaning is convenient, the inner wall is smooth without dead angles, the whole set system is closed, no dust, low noise, clean environmental protection.

　　● The control system adopts program control, easy to operate, and mix the mix of several materials.Crushing; variable combination structure, compact structure, and use.

　　This series of airflow pulverizer can process ultrafine powder of various materials in dry, high purity, low temperature, widely used in chemical, battery materials, refractory materials, abrasives, non-metallic mines, powder metallurgy, Building materials, pharmaceuticals, food, pesticides, feed, new materials, environmental protection and other industries and ultra-fine pulverization, dissipation and particle shape of various dry powder materials. Typical materials: diamond, silicon carbide, phosphate, ultrafine calcium carbonate, quartz, diatom, hydrogen calcium, bentonite, talc, mica, silica grayite; high purity pigment, luminescent powder, polishing powder, reflective material, mobile phone battery Powder; pollen, growthin, food additive, antibiotic drug, angiographic drug, Ganoderma lucidum, pearl powder and polytetrafluoroethylene et al.

　　This production line consists of ultrafine pulverizer, a grace machine, a cyclone collector, a pulse dust collector, a guide fan, and a voltage control cabinet. The material is pulverized by the raw material bin into the consensus machine, and the material is pulverized. The fluid of the introduction of the fluid is graded, and the product that meets the granularity requirement, the product is collected, the coarse material is discharged from the classifier, and the excessive powder is collected, and the cleansing gas is The fan is discharged.

　　Ingenious, should not be just a business 噱, but a fearful heart, use the ultimate serious and perseverance to create the ultimate product. ALPA Powder Technology has improved the service to the brand height through unremitting efforts, and establishes the marketing strategy of "customer satisfaction" and "market first" as the main goal. Through the innovation change of marketing services, focus on "customer satisfaction", with super Value services create value for customers and constantly improve customer satisfaction.
