[0028] Working principle: According to the working requirements, when the cement powder grinding particle size is large;

[0029] The driving block 8 of the electric control is turned to rotate clockwise 90 degrees. At this time, the driving slot 9 drives the slide bar 7 to move downward, and the slide bar 7 drives the connecting plate 6 to move downward. The connecting plate 6 drives the sliding frame 5 downward, so that the sliding bar 4, the fixed plate 3 and the rolling plate 2 move downward, and the cement clinker in the box body 1 is squeezed and ground into powder in the vertical direction.

[0030] Until the driving block 8 completes its ninety-degree rotation, the slide bar 7 is located in the middle section of the driving slot 9, and the sliding bar 4 drops to the horizontal slot at the upper end of the guide slot 14, and then the electric telescopic rod 12 is started to extend outward, and the connecting rod 11 is pushed to the right to make the pulling rod 10 move to the right. The pulling rod 11 drives the sliding bar 4 to move to the right along the horizontal slot at the upper end of the guide slot 14, so that the cement clinker is squeezed and ground into powder in the vertical direction, and the cement clinker is given lateral pressure to be rolled, which can ensure that the cement clinker is evenly stressed in all directions, thereby improving the crushing efficiency; reducing the dead angle and unevenness in the crushing process, realizing multi-directional crushing, and more effectively crushing large particles, reducing the residual large pieces of material, and improving the overall crushing effect.

[0031] When the cement powder is ground to a finer particle size, the electrically controlled drive block 8 is rotated 180 degrees clockwise. At this time, the drive slot 9 drives the slide bar 7 to move downward, and the slide bar 7 drives the connecting plate 6 to move downward. The connecting plate 6 drives the sliding frame 5 downward, causing the sliding bar 4, the fixed plate 3 and the rolling plate 2 to move downward.

[0032] Until the driving block 8 completes its rotation of 180 degrees, the sliding rod 7 is located at the lower end of the driving groove 9, causing the rolling plate 2 to drop lower, and the cement clinker in the box body 1 is vertically squeezed and ground into finer powder. At this time, the sliding rod 4 drops to the horizontal groove at the lower end of the guide groove 14, and then the electric telescopic rod 12 is started to extend outward, and the connecting rod 11 is pushed to the right to move the pulling rod 10 to the right. The pulling rod 11 drives the sliding rod 4 to move to the right along the horizontal groove at the upper end of the guide groove 14; horizontal extrusion and grinding are performed.

[0033] By driving the drive block 8 at different rotation angles, the drive slot 9 places the slide bar 7 at different heights, thereby achieving different degrees of fineness of cement powder grinding and achieving the effect that the particle size of cement powder can be adjusted during grinding.
