The research shows that when two solid particles with a certain velocity meet and collide, the crushing strength is positively proportional to the relative velocity and collision angle, that is, the crushing strength is directly proportional to the collision angle.
The collision strength of 180 degrees is 20 times of 45 degrees and 8-9 times of 90 degrees. The crushing strength is proportional to the relative velocity, and the velocity of the airflow in the general ultrafine vertical mill is supersonic (300-500m/s).
In the circular cavity structure, the impact angle decreases with the increase of the number of nozzles. In the circular cavity structure, the angle of the two nozzles is 180 degrees, but the output can not meet the needs of large equipment.
No rules, no square. The new ultra vertical mill cavity is square structure, no matter how many nozzles are, it can ensure that the particles always collide at 180 degrees, thus achieving the best grinding efficiency.
