The crushing roller comprises a group of toothed rollers 2 which can rotate in different directions and are matched with each other and a side toothed plate 3 fixedly connected to the shell 1. A plurality of groups of teeth are arranged on the tooth roller 2 at equal intervals along the axial direction, one group of teeth are finger rings and surround a plurality of tooth units on the tooth roller 2 for one circle, the teeth on the two tooth rollers 2 are arranged in a staggered mode, and the fixed teeth on the side tooth plates 3 are positioned between the two adjacent groups of teeth. Preferably, the gear roller 2 is connected to the forward and reverse rotating motor 7 through a safety coupling. The safety coupling may provide overload protection. The forward and reverse rotation motor 7 can be a servo motor, a controller is connected to the servo motor, when the torque of the servo motor is larger than a preset value of the controller, the controller controls the servo motor to rotate reversely, and the overload condition can be relieved through repeated forward and reverse rotation.

The cake enters from the hopper 10, falls between the toothed rollers 2, is crushed and falls onto the screen 4.

The screen 4 is of a structure with a high middle part and two low ends; in this embodiment, as shown in fig. 3, the screen 4 is an arc-shaped screen plate, and two sides of the arc-shaped screen plate are attached to the housing 1. Of course, the screen 4 may also take other configurations as will occur to those skilled in the art, for example, the screen 4 may be formed by two sloping surfaces having a vertical angle in longitudinal section. In this way, the small particles in the crushed cake are leaked through the sieve holes, and the large particles roll from the middle of the sieve 4 to the two ends.

The utility model discloses still include two sieve section of thick bamboo 5, sieve section of thick bamboo 5 is cylindricly, and evenly distributed has the sieve mesh on its lateral wall, and in this embodiment, the aperture of sieve mesh on the sieve section of thick bamboo 5 is the same with the aperture size of sieve mesh on the screen cloth 4. The axis of the screen drum 5 is parallel to the gear roller 2, the screen drum 5 is sleeved on the periphery of the shell 1 and is positioned at two ends of the screen 4, the hopper 10 is of a flaring structure, and two ends of the hopper are opposite to the inner wall of the screen drum 5, so that no block exists above the middle of the hopper 10. Two ends of the screen 4 extend into the two screen drums 5 respectively, and large particles rolled down from the screen 4 enter the screen drums 5.
