By setting the distance between the grinding wheel 62 and the output end of the electric rotating table 4, it is convenient to grind calcium carbonate of multiple different sizes at the same time; the chassis 61 is fixedly connected to the base 1.

[0025] A protective cylinder 3 is fixedly installed on the base 1. The setting of the protective cylinder 3 facilitates the disassembly and assembly between the base 1 and the protective cover 7, and the protective cylinder 3 is above the grinding chamber 2 and coaxial with the grinding chamber 2. The inner diameter of the protective cylinder 3 is the same as the inner diameter of the grinding chamber 2; a number of through holes are evenly distributed on the protective cylinder 3.

[0026] A conical table 5 is fixedly installed at the output end of the electric rotating table 4. Through the setting of the conical table 5, calcium carbonate can automatically move to the surroundings of the grinding chamber 2, thereby preventing calcium carbonate from accumulating at the center of the output end of the electric rotating table 4 and being coaxial with the conical table 5.

Through the setting of the suction holes 74 and the powder extraction pipe 8, the powder extraction pipe 8 can be connected to an external powder extraction and collection device. Under the action of the external powder extraction and collection device, the ground powder enters the powder extraction pipe 8 through the suction holes 74, and finally enters the external powder extraction and collection device through the powder extraction pipe 8 for collection.

[0029] In this embodiment, when in use, it can be connected to an external automatic calcium carbonate feeding device through the inner cylinder 72, so that the external automatic calcium carbonate feeding device can feed the calcium carbonate to be ground into the grinding chamber 2 in an orderly manner through the inner cylinder 72. After the calcium carbonate is fed into the grinding chamber 2, the calcium carbonate will be on the electric rotating table 4. At this time, the electric rotating table 4 is started. Under the rotation of the electric rotating table 4, the calcium carbonate will move around the grinding chamber 2.
