Furthermore, the gear shaft is a spline shaft, and the inner ring of the rolling teeth is provided with a key groove according to the tooth shape of the spline shaft, so that the connection stability is ensured.

Furthermore, the tooth section of the rolling tooth is in an oblique triangle shape and is inclined towards the occlusion direction.

Furthermore, a side scraper is arranged on one side of the gear roller, which is close to the machine shell, the contact surface of the side scraper and the machine shell is a plane, and the contact surface of the side scraper and the gear roller is teeth which can be meshed with the rolling teeth.

Present dry process granulator only has one-level whole grain structure basically, because the unreasonable shortcoming such as inefficiency or farine rate of existence of design, our dry process granulator adopts the whole grain of second grade, the utility model discloses a whole grain structure of one-level adopts the interlock of each other of cutting grain hobbing cutter to break the thin slice, the material just once can realize the breakage with the tool bit contact of cutting grain hobbing cutter, the farine can not appear basically, the oblique triangle cross-section design of cutting grain hobbing cutter's tool bit has good drive material operation and crushing effect, cuts grain hobbing cutter's tool bit size and arranges and can design according to material particle size demand, the broken even granule that obtains the distribution, the granule that is close the target particle size does not need again to push many times when the whole grain of second grade again just can pass through. The utility model discloses an one-level whole grain structure can improve whole grain efficiency greatly, and the granule hardness and the particle diameter of preparation are even, and the farine rate is low, can ensure product quality's stability.
