The base 1 is used to fix the crushing device, and the collecting bin 7 is used to collect the material after crushing. When the crushing device is used, the material is directly fed into the crushing mechanism 4 through the vacuum feeder 2 under the action of the feeding assembly 3 for crushing, so that there is no gas discharge or dust leakage in the whole process from feeding to crushing of the material, and the whole internal circulation system forms a closed space, so that the noise output of the crushing device can be greatly reduced during operation. The material can also be crushed or crushed for multiple cycles to achieve the control of the particle size of the finished product.
