Working principle of large hammer mill crusher. 1. The material to be crushed is fed into the crushing cavity by the feeding equipment through the feeding port, and the rotor drives the hammerhead to strike the material at high speed; 2. After gaining kinetic energy, the material crushes the impact plate at high speed to get the second crushing; 3.
Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
With a wide usage application, grasping some solutions to the common faults of the hammer crusher is very necessary. 1. High temperature of bearing Reasons: a. Lack of grease or too much grease; b. The bearings were broken. Solutions: a. Regularly check the hammer crusher, add grease if insufficient.
