The two pairs of arc rods 7 are respectively slidably inserted on the left and right sides of the feeding hopper 2. One end of the two pairs of arc rods 7 is respectively fixedly connected to the bottom ends of the two protective plates 6. The two pairs of limit plates 8 are respectively fixedly connected to the ends of the two pairs of arc-shaped rods 7 away from the protective plates 6, and the two pairs of springs 9 are respectively sleeved on the outer walls of the two pairs of arc-shaped rods 7. One end of the two pairs of springs 9 is fixedly connected to the outer wall of the feeding hopper 2, and the other ends of the two pairs of springs 9 are respectively fixedly connected to the two pairs of limit plates 8. Through the setting of the protective plates 6, dust can be shielded when the grinder 1 grinds the cement raw materials, thereby preventing the dust from spreading everywhere during the grinding process. Through the setting of the arc-shaped rods 7 and the springs 9, the raw materials can be squeezed against the protective plates 6 when feeding, so that the protective plates 6 are flipped, and the springs 9 are pulled by the limit plates 8 and the outer walls of the feeding hopper 2 to produce corresponding elastic deformation, thereby generating corresponding pulling force.

[0028] The use method and advantages of the utility model: When in use, the working process is as follows:
[0029] By setting the protective plate 6, dust can be shielded when the grinder 1 grinds the cement raw material, thereby preventing the dust from spreading around during the grinding process. By setting the arc rod 7 and the spring 9, the raw material can be pressed against the protective plate 6 when feeding, so that the protective plate 6 can be turned over, and the spring 9 can be pulled by the limit plate 8 and the outer wall of the feeding hopper 2 to produce corresponding elastic deformation, thereby generating corresponding tension. After the raw material enters the inner cavity of the feeding hopper 2, the limit plate 8 is pushed by the tension of the spring 9. The arc rod 7 and the protective plate 6 are reset to facilitate the opening and closing of the protective plate 6, and the motor 10 is started to drive the slide 12 to rotate through the roller 11.
