Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a calcium carbonate processing raw material grinding device. Background Art

[0002] Calcium carbonate is an inorganic compound that is commonly used in the manufacture of plastics, profiles, coatings, inks, papermaking, wires, cables and other fields. In existing calcium carbonate processing plants, when crushing and grinding calcium carbonate raw materials, the particle size of the ground particles is not ideal and the efficiency is low, which further affects the next process.

[0003] Patent CN214346820U proposes a raw material grinding device for calcium carbonate processing and production. Through the setting of the grinding tank, as well as the coordinated use of a stepper motor, a rotating shaft, a grinding bottom plate, a grinding pressing top plate, a fixed supporting pier, a material taking door, a hinge, a cover plate, a driving rod, a fixed sleeve, an arc-shaped shovel plate, a push plate, a compression spring, a vertical rod, a positioning sleeve, a fixed cross bar, a push block, a threaded rod and a fixed block, the stepper motor drives the grinding bottom plate to rotate back and forth at a certain setting ratio, and at the same time, the raw material is pushed forward by the rotating shaft and the thread of the grinding pressing top plate. The grinding and pressing top plate is driven to squeeze back and forth vertically in the opposite direction, so that the calcium carbonate raw material is ground and pressed by the grinding and pressing top plate inside the grinding jar. At the same time, the grinding bottom plate is rotated to achieve the effect of high-intensity rotation and rolling of the calcium carbonate raw material. At the same time, the grinding bottom plate rotates to drive the ground calcium carbonate particles and the inner wall of the arc-shaped shovel plate to displace, and the particles are effectively pushed to the bottom of the grinding and pressing top plate for multiple rotation and rolling, thereby achieving the effect of greatly improving the grinding efficiency of the calcium carbonate raw material while making the ground particles smaller.

[0004] In the above scheme, the calcium carbonate raw material is squeezed and ground by the cooperation of the grinding bottom plate and the grinding pressing top plate. However, after the grinding is completed, the material taking door needs to be opened manually to take out the ground raw materials. Raw materials are likely to remain on the grinding bottom plate. In addition, before the raw materials are put in for grinding again, manual intervention is required to feed the raw materials in, resulting in low grinding efficiency and inconvenient feeding and discharging.
