Airflow grinding temperature without medium smashing: low melting point, thermal sensitivity, fibrous, polymer polymer powder; flammable, explosive, easy oxidized material for ultrafine processing Moques hardness; inert gas Realize the closed circuit cycle, the inert gas circulation is used.
As a dust-free airflow classifier, one of the powder processing equipment, it can be seen when he listens to this name. It is a kind of anti-dust anti-pollution equipment, which is also responsible for the environmental protection policy that is vigorously implemented in today's country. Therefore, in recent years, the dust-free gas flow classifier is more favored by the machining enterprises.
The rotor impeller of the dust-free flow grade machine is a composite bidirectional centrifugal, and the impeller high speed is reversed. The lower portion of the impeller constitutes a negative pressure zone, and the atmosphere in the hierarchy is entry into the lower portion of the impeller. In the upper leafnopana, it is excited from the inlet. Under the radiation of fine granules, the airflow torsion is moved up, and the airflow to twist the upward activity, and there is a split rate in the axial direction and the circumference, and the air flow is hierarchically active, via the impeller. The upper entrance enters the lower impeller, squeezed from the lower impeller inlet, and the exclusible gas stream is twisted downward in the cartridge, and then flows upwards in the inner cylinder to the lower air of the impeller, such as Scars returning to the gas stream. The material output from the star feed valve falls into a high-speed twisted tube, and the material is subjected to the squeegee ring under the informance of the heart force, and the material is submitted downward in the classification cartridge. Under the insertion gas stream, the crude particulate material is slid from the wall of the conditioned ring to the coarse collector, while the fine powder is delivered to the lower micronized cyclone in the upper center of the stroke of the rotor (the inner cylinder of the hierarch " ), If the material is divided into two parts, the residual atmosphere is inhaled by the central suction in the middle of the rotor, flowing through the blade, radiates fine grain ring, and the rings, and then stroke from the middle stroke of the rotor. The continuous active reincarnation of the loop reciprocation is formed. Follow the excess atmosphere belt and because the level of stratage is high, the atmosphere shrinks, is crowded by the remaining wind, and is equilibrated with the housing level. The Yufeng port set is filled with a bag to make the destroyed atmosphere to contaminate the environment.
Dust-free gas flow classifier is widely used in chemical, minerals (especially suitable for calcium carbonate, kaolin, quartz, talc, mica and other non-mineral products), metallurgy, abrasive, ceramics, refractory materials, medicine, pesticides, food, health care Products, new materials and other industries.
powderThe body of the body is an emerging cross-industry discipline. It is the product of modern high-tech development. It is widely used in the preparation of powder. It can be divided into two categories according to the nature: one is the use of physical or chemistry. The method is coagulated in atomic, dispensing, and molecular levels, and the molecular weight is long; the other is the size of the block material to the size of the ultrafine powder with a mechanical method. Among them, the pulverization method has received the attention of all countries due to the low cost, and has become one of the most commonly used methods of powder preparation techniques. In order to achieve the ideal powder, it is difficult to make the material to achieve the desired particle size requirements at a time, and the product is often in a larger particle size distribution. In the use of various industrial sectors, the powder products tend to be in a certain particle size distribution range. In addition, during the pulverization process, there is often only a portion of the product to meet the particle size requirements, while another product does not reach the granularity requirements. If these reached the required product is not separated, they have not met the requirements. The product will be pulverized together, which will cause energy waste and some of the products of the products. Dust-free gas flow classifier has the above problems in the pulverization process, must be solved by grading. The grading of the material is one of the most basic operations in powder engineering. Its effect is mainly reflected in the following aspects: First, according to the process needs, the powder raw material or semi-finished product is excessively or too small. The particle size of the control product is within a certain range, thereby ensuring the quality of the product and improves its added value. The second is to cooperate with the polishing operation, constitute a circle flow grinding system, and the qualified powder is separated from the quality of the product, which can effectively avoid the occurrence of pollination, improve the grinding efficiency, reduce product energy consumption; It is also convenient to control the product fineness to adapt to changes in product and process conditions. This is the reason why the researchers pay special attention to the grading theory and industrial experiments of dust-free gas flow grading machines. It is because of these second aspects, grading technology has been widely used in environmentally friendly, building materials, metallurgy, fuel, ceramics, food and other industries: research and development development of grading technology and equipment development, also deeply accepted by research institutes and factory mines. Enterprises' attention. The development of any device must be guided by theory, so the grading mechanism has guiding the design and manufacturing of the classified equipment, and the development and application of basic theory research on powder technology is extremely important. Only the grading mechanism of the dust-free grading machineIn order to improve the vortex air grade machine, it can design and develop high-efficiency and energy-saving classifiers for production, improve product quality, energy saving energy, improve production efficiency and reduces production costs.
Dust-free gas flow classifier is one of the main products of Shandong El Pai, its grading accuracy and equipment crafts are ranked in the best in the domestic industry, especially in metal powders, alloy powder, Shandong Erse production. The inert gas protection airflow classifier has a high share, it has been consistently recognized by the user.
As the world's big country, China has played a positive role in maintaining world peace and regional stability, and assumes great responsibility and obligation. As a large industrial powder equipment manufacturing enterprise developed in China's economic wave, ALPA powder technology will also assume corporate social responsibility, and continue to join hands with more companies to my country's strong troops, and strengthen the road of strong countries.
