The problem of ordinary ultra-micro gas flow is: high manufacturing cost, large investment, high energy consumption, too much powder processing, so that it is also subject to certain fields; difficult to make submicron Level products, product particle size is best in 10 um, and the output is sharply decreased at 10 um, and the cost is rapidly rising; the single-machine handling capacity of gas flow is smaller (both less than 1 ton hour, can not adapt to large-scale production needs; The wear problem of equipment processing accuracy and material is still plaguing equipment manufacturers and factory users.
Domestic airflow crusher companies have faced a lot of problems, for example, the company is too small, Waiting, but in the past few years, the airflow crusher industry has continuous improvement, so it has also increased its competitive fierce. It is mainly improved in the three aspects of the gas source, raw material supply and grading.
The gas source is the driving force of the airflow pulverizer, and the requirements of compressed air can be between 0.7-0.8MPa, maintain pressure stability, even if there is fluctuations, but the frequency should not be too high, otherwise the quality of the product will be affected. Second, The gas quality, requires clean, dry, should purify the compressed air, remove the moisture, oil mist, dust, so that the pulverized mineral material is not contaminated, especially the crushing requirements of the material with high purity Height.
The feedstock is to boost the raw material in the raw material with a hoist, and then feed the raw material into the pulverization chamber of the gas flow pulverizer through the transfer valve. Raw material conveyor delivery of raw materials The concentration of automatic control keeping the raw material and air mixing chamber is relatively stable. The crushing chamber is symmetrically mounted with two pairs of nozzles, and the compressed air forms a supersonic airflow to form a raw material to accelerate, collide with each other, and pulverize the raw material into super The fine powder, crushing effect and nozzle inner diameter, distance, symmetry, and mixed concentration of raw materials and air. The inner diameter of the nozzle determines its Zui speed, distance, and determine whether the raw material acceleration path is determined, whether the speed is ideal, raw materials and air The mixing concentration also affects the particle size and yield of the product. The classification is performed by a hierarchy wheel with a high speed. The classification wheel is fixed on the center of the discharge motor at the bottom of a circular motor, driven by the motor Rotate, openings and micron powder collection systems are relatively, and maintain a certain gapIt is not too big, otherwise the unselected coarse powder into the pipeline of the fine powder collection system from the gap, affecting the quality of the product, in order to prevent such events, air seal processing at the gap. The graded wheel is mounted with a blade, and the slit between the blades is a channel sorting fine powder. The pulverized fine powder flutters with the air, and the ultrafine powder is felt to the outer wall under the centrifugal force of the graded wheel due to the genus of the grain size, and the large particles are flying to the outer wall. . Adjust the speed of the grading wheel, you can get different particle size products.
In the context of economic globalization, more and more foreign exchanges have become an inevitable trend in all walks of life, for AlPa powder, this Communication not only promotes the exchange of information, but also accelerates the pace of ALPA powder into internationalization.
