Further, the stirring plate device is coaxially connected with the transverse grinding disc.

Further, an opening portion is formed at one end, close to the first grinding mechanism, of the rotating shell.

Furthermore, the spiral slideway is two, two the spiral slideway is crisscross to be set up.

Furthermore, the number of the grinding ball assemblies is two, and the two grinding ball assemblies are respectively arranged on the two spiral slideways.

Further, the grinding ball assembly comprises a supporting arm fixed on the rotating shell, an elastic rope connected with the supporting arm and a grinding ball connected with the elastic rope.

Compared with the prior art, the calcium carbonate crushing and grinding device has the advantages that the stirrer is driven by the first motor to rotate, so that the through hole is communicated with the guide pipe in a reciprocating mode to realize intermittent blanking, the primary grinding mechanism and the secondary grinding mechanism grind materials, agglomeration and non-blanking are prevented, the crushing and grinding effects are good, and the calcium carbonate crushing and grinding device is simple in structure, good in effect, easy to realize and cost-saving through the arrangement of the three-stage mechanism.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for the description of the embodiments are briefly introduced below, the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:

fig. 1 is a schematic structural view of a calcium carbonate pulverizing and grinding apparatus according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a calcium carbonate grinding device includes a frame 1, a grinding mechanism 2 disposed on the frame 1, a first-stage grinding mechanism 3 disposed below the grinding mechanism 2, and a second-stage grinding mechanism 4 disposed below the first-stage grinding mechanism 3, wherein the first-stage grinding mechanism 3 is communicated with the grinding mechanism 2, and the second-stage grinding mechanism 4 is communicated with the first-stage grinding mechanism 3.
