This utility model relates to the field of raw material crushing technology and discloses a raw material crushing device for the production of environmentally friendly building materials. It achieves screen hole cleaning by setting up a drive roller, teeth, screen frame, screen holes, and brush blocks. Gear A drives the screen frame to rotate circumferentially between the drive roller, driven roller, and auxiliary roller through the meshing of the teeth and screen holes. When the screen frame rotates, it drives the crushed material to pass through the screen evenly. Qualified material falls downwards through the screen holes, while unqualified material rotates synchronously with the screen frame after being propelled by a deflector plate. When the screen frame drives the material to the teeth, the teeth, due to their deep penetration into the screen holes, can push out the material blocked or stuck inside the screen holes. Subsequently, the screen frame continues to rotate, driving the material to the brush blocks. The bristles at the end of the brush blocks brush the material into the crusher body for secondary crushing. The sticky material pushed out by the teeth at the screen hole openings is also brushed away by the bristles at the end of the brush blocks, thus achieving the effect of cleaning the screen holes.

This invention discloses a method for processing electromagnetic coils, relating to the field of coil processing and production technology. The method includes placing the coil into an inner tank within an impregnation tank, sealing it, and then evacuating the tank until all air is completely removed. Enamel is injected into the inner tank to completely cover the coil. A segmented pressurization stage is then initiated, controlling the inner tank to rotate forward and backward, and removing foam from the enamel using a defoaming component.
