What is the operation mode of screw feeding fluidized bed jet mill

Fluidized bed jet mill is the leading equipment in jet mill, and its application scope is more extensive than other types of equipment. Fluidized bed jet mill, with its high production efficiency and low wear, has become the first choice for ultra-fine grinding of silicon carbide and other materials with high hardness and high wear resistance. Taking the screw feeding fluidized bed jet mill of Qingdao Youmingke Powder Machinery Co., Ltd. as an example, its working principle is introduced

The screw feeding fluidized bed jet mill is composed of a silo, a screw, a crushing chamber, a high-pressure inlet nozzle, a classifier, a discharge port and other components. The materials in the crushing chamber enter the silo through the flap valve and are sent to the crushing chamber by the screw conveyor. The airflow enters the fluidized bed through the nozzle, and the particles collide at the intersection of high-speed jet airflow, which is located in the center of the fluidized bed. The particles are crushed by the high-speed impact of airflow on particles and the mutual collision between particles. The particles have little contact with the cavity wall and have little impact, so the wear is greatly reduced< Br, The coarse powder is settled by gravity and returned to the crushing area for further crushing< Br/>The screw feeding fluidized bed jet mill is one of the main equipment of Qingdao Youmingke. In addition, there are other feeding methods of jet mill, air classifier, graded impact mill and other equipment. The process can be changed according to user needs to achieve the processing method suitable for Zui
