With the idea of "Customer need, is our works; Customer dream, is our targets.�the Real-Long people warmly welcome the customers home or abroad for business. Overview of industry Along with the development of the industry modernization, the request of the performance of material become higher and higher. Powder material is an important branch of material domain. In order to improve the performance of materials, to minimize the basic cell of materials is the target that people hope to attain. The superfine powder could improve the performance of ceramic material, powder metallurgy material, chemical industry material, construction material, coating material and medicinal material. Superfine pulverizing technology is a new technique on materials process in order to meet the demands of the development of modern new and high technology industry. At present, there is no hard and fast defined about �uperfine Powder�at home and aboard, but we usually called it �uperfine Powder�whose powder diameter is less than 30 micron, this is because solid material can�t been milled so ultrafine by using any traditional methods. The diameter of superfine powder is less than hair (the diameter of hair is usually 70-80 micron). The traditional pulverizing method could attain about 45 microns. Superfine pulverizing technology could attain 10 microns, even attain submicron (0.1-1μm) or nanometer powder. Although there are only several dozens of micron from 45 microns to submicron or nanometer, but if the diameter less than submicron, its surface area, optical character, electrical character, magnetical character, energetics character and surface feature will be changed. We could acquire transnormal effect, so that the price of material will increase with transnormal scale. Overview of enterprise technique Real_Long is factory professional in producing the Supersonic, Cryogenic, Fluidized Bed Superfine Powder Pulverizing/Classifying equipment, our factory have experts on aerodynamicist, structure mechanics, metals material science, machine construction, powder metallurgy science etc. Under the direction of the expert Gen. Wang Changqi from China Institute of Aerodynamics（he is the inventer of the first Supersonic Jet Pulverizing in China）, we have successfully produce three Supersonic, Cryogenic, Fluidized Bed Superfine Powder Pulverizing/classifying equipment, their type is CF26, CF29, CF50, they could be used in large-scale production and laboratory. Many advanced international technologies should be introduced, digested and absorbed to apply to produce these three equipments, such as recycle micronizer, Spiral Jet Pulverizer, impact jet Pulverizer, reverse jet pulverizer, AFG fluidized bed reverse jet pulverizer, the world� most advanced multi-point Injection technology, fluidized bed technology, Horizontal classification technology have been concentrated in these three equipment, realizing integrated technology system containing multiple flow field, fluidized material layer and horizontal classification, incarnating latest development of using pneumatic technology in superfine Pulverizing/classification technics. Scope of the use Our equipments have got the extensive application in abrasive, refractory material, metal ore, nonmetal ore, superfine pulverizing of building material, kinds of battery material the photocopying toner, commodities chemicals, luminescent material, high purity materials etc. With High pulverizing efficiency, accurate classification, improve product output, particle shape control technology, the equipment has reached international advanced level. We could help to design, manufacture and adjust the jet pulverizing/classifying system, also could training the operator for customers. Even we could help to rebuild or optimize the old equipment for clients, to make the performance of equipment upgrade. l Commonly application The equipment could mill all kinds of material which could be milled on traditional pulverizer, but also could mill powder which strictly prescribe the maximal diameter and size distribution is confined, such as kaoline, talcum powder, copycat powder, coating, mica, hormones, alumina etc. l High purity application Equipment with are made of stainless steel could mill the materials whose request of impurity content is high or sensitive to iron, meanwhile could meet the particles size and size distribution. Typical material is phosphor, titanium pigment and kinds of high purity pigment. l Thermal Spray coating material application The most outstanding advantage of equipment is in producing thermal spray coating materials; it is the best method to mill kinds of metal coating materials by sintering, agglomeration and alloying. And the particles powder meets the size request and not loss spherical rate. Typical application: Co-WC powder, chrome oxide powder, Lead sesquioxide powder, Chromium carbide powder, zirconium oxide powder, Ni Base Alloy-Chromium Carbide,etc. Almost all the powder fo thermal spray gun of HVOF is pulverized by this kind equipment in aboard. l Abrasive or hard materials application The equipment could mill the hard materials whose hardness is higher than seven grade of Mohs�cale. The equipment use ceramic, horniness alloy classification impellerpump to make the abrasion very little. The speed of classification impellerpump could be adjusted between 0 ~22000 r.p.m, the pulverizing parameter could optimize to choose, so that it is more convenient to produce different size abrasive. Typical application: silicon carbide, boron carbide, titanium carbide, kinds of ceramic, carborundum, synthetic diamond etc. l Low temperature application The equipment could operate under the supersonic airflow, the temperature in grinding unit will drop to dozens degree below zero, it could mill heat-sensitive material and plasticsubstance without cooling by fluid nitrogen. The less production cost but higher benefit. Typical application: sulfur, pesticides, Epoxy resin, Molybdenum disulfide, Polytetrafluoroethylene, ruber, pharmaceuticals, health food etc. l Pharmaceuticals, food, Biotechnology Pharmaceutics and commodity chemical industry application Equipment with are made of stainless steel could mill materials into powder used in pharmaceuticals, food, biotechnology pharmaceutics and commodity chemical industry. Its feature, such as low temperature pulverizing, high-purity operation and fine finish and easy to clean, could use to mill powder in pharmaceuticals, cosmetics and food process industry perfectly. It could not only raise the biological utilization rate and curative effect of pharmaceuticals, but also could reduce the production cost. Typical application: farina, pearl powder, Ganoderma lucidum, gen-seng, dried fruit, tuber fleeceflower, capsicum, medicine of stomach, Nimodipine, antibiotic medicine and radiopaque medicine. l Mine application: The equipment could pulverize many kinds of mine ore, the supersonic airflow could mill the ore into powder less than 10 micron, it could reduce the cost of mineral products processing and environmental pollution, increase the output. Typical application: gold ore, alumina ore, superfine coal ore, copper ore, nickel ore and kinds of building ore etc. The compose of equipment and working principle It consists of air compressor unit, clean and dry air unit, supersonic airflow grinding unit, powder grading unit, cyclone collecting unit and exhaust fan unit etc. The clean and fresh compressed air get across the special design Laval Nozzle form supersonic airflow with 3.08 Mach, by several nozzle with opposite deposited the compressed arifolw spray into the grinding chamber, meanwhile the particles from the feeding unit get into the grinding chamber and make it speed up. Then the particles collide and crush into each other on intersections of jet to attain pulverization goal. After pufverized, the ultra-fine particles get into the grading unit and are grading by the powder-grading unit under the effect of centrifugal force according to the particles size, part of further fine particles are collected into cyclone collecting �Functions: Main parameters: TypeIterm finess（d97μm） Air consumption（m3/min） Grinding press（Mpa） CF-26 1.5-40 1.6 0.8-1 CF-50 3.5-60 40 0.8-1 Capacity（kg/h） Feeding granularity（目） Air compressor power（kw） Total power(kw) 0.5-25 -125 15 3 50-1000 -125 245 37 �The test and analysis report by scanning electron microscopy Fineness >3 3-2 2-1 1-0.5 0.5-0.4 0.4-0.3 0.3-0.2 0.2-0.1 <0.1 Remarks Silicon oxide 1.04 2.08 3.91 3.91 2.6 3.91 5.21 40.89 36.46 The particles are conchoids break, the size <3μm,the particles edge clearly, fine powder is roundness without edge.
