The working principle of the cone crusher is the same as that of the gyratory crusher, but it is only suitable for crushing machinery for medium or fine crushing operations. The uniformity of the discharge particle size of the medium and fine crushing operations is generally higher than that of the coarse crushing operations. Therefore, a parallel area must be set up in the lower part of the crushing cavity, and at the same time, the rotation speed of the crushing cone must be accelerated so that the material can be placed in the parallel area. subjected to more than one squeeze.
The crushing of medium and fine crushing is larger than that of coarse crushing, so the loose volume after crushing is greatly increased. In order to prevent the crushing chamber from being blocked due to this, the total discharge section must be increased by increasing the diameter of the lower part of the crushing cone without increasing the discharge opening to ensure the required discharge particle size.
The discharge opening of the cone crusher is small, and the non-crushed material mixed into the feed is more likely to cause accidents, and because the medium and fine crushing operations have strict requirements on the discharge particle size, the discharge opening must be adjusted in time after the liner is worn, so the cone crusher The safety and adjustment device of the machine is more necessary than the coarse crushing operation
