Which kind of airflow pulverizer is suitable for boron powder processing? EPIC Powder Machinery

Boron is a black or silver gray solid. The crystal boron is black, second only to diamond in hardness and brittle in texture. If you want to process boron powder to micron grade superfine powder, you need to use air flow mill. So which model of air flow mill is more suitable for the processing of boron powder? Now let's take a look

The equipment generally used for boron powder crushing is MQW air flow mill, which is the mainstream model of air flow mill&mdash& mdash; Fluidized bed jet mill is a kind of equipment that uses high-speed airflow to crush dry materials. Due to the high utilization rate of jet energy, it does not heat up, has no pollution, has little wear, and has high accuracy& hellip; It is widely used for ultra-fine grinding of low-temperature, high-purity and hard materials. Inert gas can be used as a medium for closed circuit grinding of flammable, explosive and oxidizable materials, and the inert materials can be recycled. MQW air flow pulverizer consists of air flow pulverizer, cyclone collector, dust remover, induced draft fan, electric control cabinet, etc. The principle is that the compressed air, after being filtered and dried, is sprayed into the crushing chamber at high speed through Laval nozzle. At the intersection of multiple high-pressure airflow, the material is crushed by repeated collision, friction and shearing. The crushed material enters the grading chamber with the rising airflow. Under the centrifugal force generated by the high-speed running grading impeller and the centripetal force generated by the airflow, the coarse and fine particles are separated, Fine particles meeting the particle size requirements enter the cyclone collector and dust remover for collection through the blade gap of the grading impeller, and coarse particles are thrown out by the grading impeller and dropped to the crushing area for further crushing. MQW air jet mill has superior performance. First, its combination structure is flexible, which can be crushed and classified separately; Second, it can be connected in series at multiple levels: the connected machine is equipped with 1-5 level graders to produce products with narrow particle size distribution requirements; Moreover, its crushing particle size range is wide, the particle size of the finished product is adjustable between D97=3-150 μ m, and the particle shape is good; In addition, the whole system is closed for crushing, with less dust, low noise and clean production process; Moreover, the control system adopts program control, which is simple and convenient to operate. Therefore, it is widely used in chemical industry, minerals, metallurgy, abrasives, ceramics, refractories, pharmaceuticals, pesticides, food, health products, new materials and other industries
