[0036] The working principle and use process of the utility model are as follows: when in use, the insulation brick raw materials that the user needs to crush pass through the feed port 2, and the larger insulation brick raw materials fall on the top of the inclined plate 8. When the inclined plate 8 is subjected to the downward pressure, the first spring 10 will be compressed for shock absorption. Since the top of the inclined plate 8 is an inclined surface, the insulation brick raw materials will enter the inside of the crushing roller 61, so that the insulation brick raw materials can be crushed. Then the motor 64 is started to drive one set of gears 63 to rotate, and the rotation of one set of gears 63 drives the other set of gears 63 to rotate.
