Therefore, the research and design of the straw pulverizer also have very important significance on the development and utilization of biomass energy.
The cutter and the cutter head of the existing straw crusher are combined in a welding mode when the existing straw is crushed, so that the cutter and the cutter head need to be thoroughly replaced after a few cutter teeth in the cutter are damaged, and unnecessary waste is caused. The straw crusher adopts a cutter with uniform tooth shape, and the single tooth-shaped cutter causes the problems of uneven granularity of crushed particles and the like due to inconsistent shapes of straws in the processing process.
And the straw pulverizer is not provided with a closed negative pressure material suction device, so that the processed straw particles are scattered in the air, and great dust pollution is caused to the environment.

The impact crushing process of the solid materials is actually that solid material blocks or particles are deformed and crushed under the action of mechanical force. It is clear that the material can only be broken if the breaking force is sufficiently large, with the stress generated instantaneously exceeding the strength limit of the material. The amount of energy or force for breaking up the particles is therefore in fact a problem of the relative speed between the tool and the particles, between the wall and the particles or between the particles and the hammer. The relative speed is high, the crushing force is high, and the strength of the crushed material is high. The speed of impact between the blade and the material, i.e. the speed of the material relative to the blade, is clearly greater the greater this relative speed, the greater the impulse that can be provided, and the greater the force that acts on the material. The most advantageous way of collision is therefore to have the material collide against the hammer blade. But consider that straw itself because fibre content is many, toughness is big, and the quality is also light, so generally difficult accomplish to let straw and crushing cutter collide in opposite directions, consequently rely on first dogtooth 403 and second dogtooth 706 to cooperate in this application, tear the straw, and then smash the straw.
