[0003] The prior art CN219943147U discloses a cement roller press feeding device, which can adjust the mounting frame to slide up and down by installing a spring and utilizing the sliding groove and the sliding rod to slide together, wherein the telescopic cover is a telescopic protective cover to prevent small particle agglomerates from flowing out and does not affect the up and down movement of the mounting frame. When large particle agglomerates fall on the feeding frame, the spring elastic force is used to buffer them and reduce the impact on the feeding frame. By installing a crushing rod, the motor is used to drive the crushing shaft to rotate and the crushing rod to rotate at the same time, and the large particle agglomerates entering the feeding frame are simply crushed by the rotation of the crushing rod to avoid clogging the feed port.

[0004] The above-mentioned prior art will increase the amount of fine powder in the material when crushing large-particle agglomerated materials. If the fine powder accounts for a large proportion, it is easy to flow directly between the rollers during extrusion and is not easy to form a material cake, resulting in landslide and material rushing, causing vibration of the roller press.
