The laboratory airflow crusher is widely used for its large production capacity, high degree of automation, high product particle size, narrow grain distribution, high purity, large activity, and good decentralization, which are widely used.
Silicon carbide microfilling is a super hard material. It is widely used in aspects of abrasive mill, resin polishing wheel, and diamond polishing wheel. The silicon carbide itself is high. The particle size distribution reaches the scope of the limited, which is very difficult for the crushing and classification of silicon carbide microflower powder. With the development of industrial production, technological progress, and market demand, Requirements, including high productivity, low energy consumption, stenosis of particle size distribution and low pollution. The MQW series laboratory produced by Qingdao Youmingke is suitable for ultra -fine crushing of super -hard materials such as silicon carbide, diamond, cubic boron nitride. The principle of the MQW laboratory airflow crusher is that under the action of high -speed airflow, the particles are crushed through the impact collision, friction, and cut of the particles between particles or particles and the target. The crushing of air flow has the following characteristics: ① high -speed airflow will generate high speed to particles, the particle impact strength is high, and can get micrometer or even sub -micron level ultra -fine powder; Narrow, smooth granules, and good granules; ④ The airflow sprayed by the nozzle will decrease due to the throwing effect temperature, which can be used for crushing thermal material. At present, the MQW air flow crushing and classification equipment are an irreplaceable ultra -fine processing equipment for the silicon carbide microfilling industry. Taking the laboratory air crusher and classification system as an example, its airflow crushing and classification process are as follows: (1) Holocated wheels and system air volume pairs. According to the principle of grading, the impact of silicon carbide microfanca products obviously needs to increase the speed of the grade wheels on the grading of silicon carbide microfilling. Get the particles as much as possible and the minimum resistance as possible. In order to obtain the accurate grades of silicon carbide microflower, it is not economically increasing to increase the rotation speed of the hierarchy. It is also necessary to reasonably control the proportion of the auxiliary air to the main air volume. For sensitivity. However, the decrease in the total air volume will lead to a reduction in the amount of treatment, which is obviously not economical. Therefore, the system should be weighed the advantages and disadvantages when the system is running, and the best operating parameters should be selected. (2) The feed method of raw materials and the effects of decentralized on product performance commonly used vibration feeding and spiral feeders, not only poor uniformity, severe parts of the parts, but also directly affecting the grading effect. In the production, the method of combining vibration feeders+fans+long tube gases can be used to ensure that the powder entering the classroom is uniform and quantitatively fed. Three winds introduced by class outdoor jackets further help the dispersion of fine powder, which makes production operation stable, workers are easy to operate, and at the same time can ensure the quality of the product. At the same time, to ensure that the qi concentration of the raw material is appropriate and scattered, it is to improve the grading efficiencykey. (3) Product performance adopts silicon carbide micro-powder products produced by the MQW laboratory airflow crushing machine and the classification system, which can fully meet the granularity of microfiny products such as W4, W10, W7, WS in the GB/T 2477-83 standards used in my country's abrasive industry The distribution requirement, and meets the particle size distribution requirements of the JIS 86001-1987 industrial standards used by Japan for raid microfream, and the granular distribution requirements of products such as F1000, F1200, F2000 and other products are 85%. In the ultra -fine crushing of silicon carbide, the MQW laboratory airflow crusher has the advantages of high accuracy, no wear, high finished product rate, etc., and is widely used in many super -hard material manufacturers at home and abroad.
