This article explains the principle of the superfine air classifier and the reason for the blockage EPIC Powder Machinery

In our crushing operation in the current industrial production, the application of ultra-fine air classifier is mainly aimed at the effective crushing of solid particles, and it is also a kind of crushing equipment that we commonly use in the ultra-fine crushing process of products. So what is the working principle of this jet mill

In the production process, the superfine air classifier mainly uses compressed air to form a supersonic air flow through the nozzle inside the equipment after being frozen, filtered and dried in the equipment. The material to be crushed in the grinding chamber presents a fluidization form after being injected into the grinding chamber through powerful pressure rotation. In the rotary damage chamber, the accelerated materials gather at the intersection of the jet airflow of several nozzles, resulting in severe collision, friction, and shearing to reach the ultra-fine damage of particles. The damaged materials are transported to the impeller grading area by the rising air flow. Under the centrifugal force of the grading wheel and the suction force of the fan, the separation of coarse and fine powders is realized. The coarse powders return to the destruction chamber according to their own gravity and continue to be destroyed. The qualified fine powders enter the cyclone collector with the air flow, the fine dust is collected by the bag filter, and the purified gas is discharged by the induced draft fan. After the production of superfine air classifier, it provides convenience for many industries and also improves the benefits. During production, there are sometimes jams, which make it impossible to work normally. Sometimes it is a mechanical problem, and sometimes it is caused by improper operation. How to deal with the jams caused by improper operation? Now let's talk about EPIC Powder Machinery superfine air classifier. 1. Because the feeding speed is too fast, the load increases instantaneously, forming a blockage. Therefore, pay attention to the current pointer when feeding. If it is overloaded, it should be reduced in time, because the motor will be burnt out for a long time. Or change the feeding mode, and use the feeder to feed. The operator can move or automatically, depending on the situation. 2. If the screen mesh is closed or the hammer is aged, it will be blocked. Therefore, the equipment should be checked regularly to improve production. 3. If the discharging is not smooth and the feeding is fast, cold blocking will occur. After discovery, clean the conveying equipment and adjust the feeding amount, so that the equipment will operate normally. EPIC Powder Machinery has produced superfine air classifier for many years. It has profound technical background and rich production experience, and can provide free incoming material experiment and detection
