Classification of airflow pulverizer

Today, I will talk about the classification of the airflow crusher. The ultrafine pulverizer is composed of silo, mechanical pulverizer, air blower, cyclone, vibrating screen, liquid nitrogen tank, etc., the deep-cooling pulverizer system is refined by liquid nitrogen as a cold source, and it is crushing at low temperatures by cooling. After the crushing state, enter the mechanical pulverizing cavity through the impeller high speed rotation, the material and the blade, the tooth disc, the material and the material are enrolled under the integrated effect of collision, shear, friction, etc., to achieve a crushing effect. After the airflow pulverizer is filtered, the pulverizing cavity is sprayed through the Raval nozzle, and the material is repeatedly collided, friction, shear and pulverized, and pulverized material in the intersection of the multi-shaped high-pressure airflow. Next, the rising airflow is moved to the hierarchical region, and the crude material is separated under the powerful centrifugal force generated by the high-speed rotation, the fine particles that meet the particle size requirements are collected by the grading wheel into the cyclone and the dust collector, and the crude particles drops to the pulverization. The district continues to smash. Ultrafine pulverizer is low, and all of the lifescas is used in high quality wear-resistant materials at home and abroad. It has long service life. A small amount of easy wear parts are made of special hard resistance, small size, light weight, easy to replace the accessories. This is the classification of airflow pulverizer.

It can be divided into two forms: flat airflow pulverizer and fluidized bed airflow pulverizer. Flat ultrasonic air current pulverizer: The compressed air brought the pulverized raw material into the pulverizer by a feeder, and the compressed air injected a supersonic airflow through several grinding nozzles that were uniformly distributed around the pulverizing chamber. The high-speed airflow forms a strong swirling in the pulverization chamber to collide with the pulverized raw material particles entering the pulverizing chamber to collide with each other, and the purpose of ultrafine powder mill is achieved. Fluidized bed airflow pulverizer: Compressed air accelerates into the supersonic gas stream, through the crushing chamber around the four pull nozzles. In the pulverization zone, the material accelerates up and down flow in the ultrasonic gas stream, at the intersection of the nozzle, the accelerated material particles collide with each other and pulverize. The crushing material is delivered to the classification area by an upward gas stream. Due to the high speed rotation of the stage, the qualified fine powder enters the cyclone separator with the air flow, the collector collects the coarse powder that does not meet the fineness requirements, and returns to the crushing area further ground.

Welcome to the classification of gas flow crushers.
