Super-micro gas flow grinding is made of a large part of a crusher, a cyclone separator, a pulse dust box and a fan, has a variety of overall performance, production process, uniform, no screen, non-mesh, uniform particle size. Continuous progress. It utilizes the relative movement between the active gear disc and the fixed tooth disc, or the gas high speed flows the material to obtain the material to teeth impact, friction, and materials from each other, and the powder is pulverized by the rotating centrifuge and the air machine. Enter the cyclone separator, then passed through the shutter, dust into the pulse dust cleaning tank, and the filter is adjusted by filter cartridge and recovery. The whole machine is designed according to the GMP standard, all of which are made with stainless steel materials, and there is no dust in the production.Airflow pulverizer is also the airflow pulverizer we know, in industrial processing, a common equipment, the following small series is to introduce the principle and application of the airflow pulverizer.
1. Process principle of airflow pulverizer
The airflow pulverizer is a high-speed motion of the gas stream that causes a strong impact collision and friction between the particles and the instrument wall by means of high-speed motion of the airflow. Among them, the fluidized bed gas flow pulverizer is the most advanced multi-nozzle technology, fluidized bed technology and turbine grading technology, realizing the diversification of flow field, material layer fluidization, grading horizontalization. The fluidized bed gas flow pulverizer is pulverized with fluid-compressed air as a working medium, and the fluid speed is as high as 300-500 m / s.
The working principle is that the compressed air is emitted into the pulverizing region after the radiometric airflow is accelerated into a supersonic gas flow. In the pulverization zone, the accelerated material is integrated at the intersection of each nozzle. Here, the particles are smashed with each other. The crushing material is delivered to the grading area by a negative pressure rising airflow, and the fine powder reaching the particle size required by the inner classifier, and the coarse powder that does not satisfy the particle size continues to be pulverized. The qualified fine powder is collected by the cyclonic separator with the airflow, and the dust contains the dust-filled dust collector filter into the atmosphere. 2, the process characteristics of the airflow pulverizer
The process characteristics of the fluidized bed airflow pulverizer are: high-speed particles do not collide with the interior wall during pulverization, and the object material does not pass the nozzle. Therefore, the wear is extremely light, the product is not polluted. The upper part of the host is equipped with a horizontal grading wheel, which prevents coarse particles from entering the finished product. Since the principle of fluidized bed (the airflow expansion is suspended, the rubber is pulverized, friction is pulverized) and the horizontal turbine is provided.The grading device, compared to other types of gas flow, the airflow is better, energy saving is 30-40%. The particle size distribution of the product is narrow and has no large particles, the degree of automation is high, the noise is small, and the structure is compact.
3, the effect of the process parameters of the gas flow crusher on the long diameter ratio of the silicahydrate
(1) Influence of grading rotation speed on the long diameter ratio of silicon gray stone
Fluidized bed airflow pulverizer grading wheel The speed of the speed on the long diameter of the silica grayite has a significant effect, Liu Haixin et al, the effect of different graded rotary speed on the long diameter ratio of the silica gray stone, its research shows that with the continuous increase of the grading wheel speed, silicon The long diameter of the gray stone is gradually increasing, and after a top peak, its long diameter will decrease rapidly.
(2) The influence of the gas flow pulverization pressure on the long diameter ratio of the silica gray
When the grading wheel speed is constant, with the increase of the gas flow, the average length of the product is significantly short, but average There is no obvious fluctuation in the diameter, so the overall perspective, with the increase of the gas flow, the silica graystone is reduced.
Airflow pulverizer is one of the main products of Shandong El Pie Powder Technology Co., Ltd., the airflow pulverizer produced by Erbai, Shandong Province has a higher share of technical precipitation and renewal in the market. The new generation of gas flow pulverizer has a more fine particle size, more accurate and higher efficiency. At present, more than 5,000 enterprises in China, the hotline 13061397961.
China manufacturing has been eliminated Or the promotion of the fork, AlPa Powder Technology as a professional powder equipment manufacturing enterprise with more than 20 years, the chairman and management team deeply, through independent development, joint development, and manufacturing intelligent manufacturing and green, it is constantly While achieving high quality development, leading traditional manufacturing industries continue to transform into intelligence and green development direction.
