[0002] At present, in the pharmaceutical, chemical, food and other industries, coarse crushing is a supporting equipment for the front process of fine grinding processing. It is not limited by the viscosity, hardness, softness and fiber of the material, and can achieve a good crushing effect on any material.

[0003] The working principle of the needle bar crusher is to use the gap between the high-speed rotating moving needle and the fixed needle to repeatedly hit the material to achieve the crushing process. In order to better carry out the coarse crushing process of the material, a needle bar crusher is needed.

[0004] In the existing needle bar crusher, when the rotating needle bar crushes the material, if a large amount of material enters at the same time, the needle bar is likely to get stuck and cause damage, and it is not easy to transmit the crushed material to collect it for the next step of processing.
