Hammer crushing principle
The hammer mill uses a physical impact type of pulverizing method to operate at a high speed, so that it moves relative to the fixed pinion around it and the fixed ring gear around it. The material passes through the high-strength collision and material of the hammer in the hammer mill. A mutual impact can be obtained to obtain a pulverized material. The material that has been pulverized in the hammer mill is then subjected to high-speed rotation and is filtered from the sieve hole into the prepared bag by the centrifugal force. In the working process of the hammer mill, the worker puts the material into the crusher through the feed port, and then the hammer mill crushes the material and pulverizes it at a high speed. While the pulverizer hits the material, the material is further subjected to the friction and pulverization of the various components in the pulverizer. Under such circumstances, the raw material can be further pulverized. In the process of pulverizing the raw material by the pulverizer, particles of different sizes may appear, because the particle size is different, small particles are filtered out, and large particles remain in the pulverizer for further pulverization. Under such circumstances, an air circulation layer is formed in the pulverizer. The existence of this circulation layer affects the pulverization efficiency of the pulverizer and greatly increases the energy consumed by the pulverizer.
Effect of the shape of the crushing chamber on the performance of the hammer mill
Through the understanding of the pulverization theory of the pulverizer and according to scientific research, in the process of pulverizing the raw materials, it is necessary to ensure the pulverization efficiency of the pulverizer, and to grasp the degree of comminution, and it is not possible to have excessive pulverization or If the smashing is not complete, then we need to change the shape of the crushing chamber through continuous reform and innovation. In fact, the change in the shape of the pulverization chamber is a change in the shape of the sifter, thereby reducing the formation of the air circulation layer in the pulverization chamber. In this way, the pulverization efficiency of the pulverizer can be comprehensively improved. In recent years, through continuous efforts and innovations of technicians at home and abroad, in order to improve the pulverization efficiency of the drunken machine, a drip-shaped and elliptical pulverization chamber was invented, which improved the pulverization efficiency of the pulverizer to some extent.
The drop type hammer mill refers to a pulverized shape of a water drop type. At the beginning, the shape of the crushing chamber of the hammer mill was round. After a series of reforms, the circular shape was changed into a water droplet type, which changed the bending degree of the sieve and hindered the formation of the circulation layer to some extent. This greatly improves the pulverization efficiency of the pulverizer and also facilitates the discharge of the raw material into the pulverization chamber. Research practice shows that the drop-type hammer mill has an efficiency of at least 15% higher than that of the conventional hammer mill.
