Working principle of air current pulverizer

Today, we will discuss the working principle 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. The working principle of the gas flow pulverizer is described below.

Airflow pulverizer, unlike other crushers, under high-speed airflow, the material passes the impact between its own particles, the gas stream impacts shear effects and materials and other components, friction, and shear. Pull the material.

The airflow pulverizer is a huge kinetic energy using the material under high speed airflow. It results in a severe friction between the high-speed collisions and the particles in the grinding chamber. At the same time, the high-speed airflow has a shear effect on the material to achieve the purpose of crushing materials. It can processes raw materials into very fine powder. The technology is almost universal in all fine processing industries such as chemical, plastics, mining, metal materials, and has a special position in many specific powder fields.

Since the 1930s airflow pulverizer, after the efforts of many researchers, their structures are constantly updated, and the types are increasing. There is a flat plate or disc, circulating gas flow mill, collision gas flow mill, fluidized bed gas flow grinding, target gas flow mill, supersonic speed flow mill, etc.

Need to solve energy-saving problems of airflow crusher

However, the equipment manufacturing cost is high, energy consumption, and the processing cost is also large; the single-machine processing capacity is less than 2T /h, not suitable for large-scale production; product particle size is difficult to achieve submicron grade, the output is greatly reduced during 10 um or less, and the cost of processing has increased dramatically.

In the face of serious energy-saving problems, the airflow pulverizer solves energy-saving problems and will greatly expand the application range of airflow crushers. Considering the current energy-saving environmental protection requirements, energy saving will be one of the main directions of the improvement of the gas flow pulverizer.

Welcomes the above working principle of the pulverizer.
