Introduction to SCM Ultrafine Grinding

SCM ultrafine grading grinding to impact the main crushing, both shear, extrusion, air crushing and other crushing mechanism of the combined effect of the main three kinds of crushing methods:
1) impact smash. The material to be pulverized enters the center of the grinding disc of the grinding chamber, and the pulverized material composed of the impact member and the grinding wall is subjected to the centrifugal force by the high-speed rotation of the grinding disc, and is first subjected to the impact pulverization of the impact member Crushed, did not reach the qualified particle size of the particles by the impact of accelerated parts, rushed to the toothed grinding wall by the grinding wall counterattack crushing effect of the second crushing. So repeatedly until the qualified particle size is reached. The following are the same as the ”
2) cutting and crushing crushing. During the high-speed rotation of the disc, the distance between the front end of the impact part and the inner wall of the toothed grinding wall is periodically changed, and when the impact part is opposite to the tooth top circle, the distance is the largest, Force to reach the strength of the material crushing limit, the material particles are crushed. The following are the same as the ”
3) airflow crushed. Airflow crushing is mainly due to the impact of the collision between the main particles in the grinding chamber equipped with tooth-shaped grinding wall is based on the impact of increased impact between particles of this purpose. The grinding wheel in the process of high-speed rotation through the minimum gap will form a reduced diameter jet jet, and this time the air flow is the material flow, with the grinding wheel continues to rotate, this gas jet into the tooth groove, The flow of particles in the tooth groove collides with each other, so as to achieve the purpose of improving the pulverization efficiency of the crushing chamber. The following are the same as the ”
In order to understand the crushing mechanism and the crushing effect of the grinding chamber in the toothed grinding chamber, the crushing chamber with the blade type impact part was simulated numerically, and the crushing chamber with the rod impact part was experimentally verified. The following are the same as the ”
SCM Ultrafine Mill indoor disc high-speed rotation, crushing indoor air flow of the complex form of movement for the gas-solid two-phase turbulent movement, direct analysis of material particles in the form of movement is more difficult. In the crushing chamber, the gas flow field of the pulverized chamber is simulated by the computer. The numerical simulation of the gas flow field in the pulverizing chamber can be carried out by using Fluent software, and the moving form of the material particles can be obtained indirectly by analyzing the characteristics of the gas flow field in the pulverized chamber. In the process of analysis, the flow field is incompressible, and the standard K-ε two-equation turbulence model is used. The multi-reference (MRF) model is used to solve the disc rotation problem. The gas flow field in the pulverized chamber is numerically simulated to study the motion form of the material particles.
