Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A calcium carbonate grinding device comprises a fixed support base 1, wherein a grinding box 2 connected in a rotating mode is arranged on the fixed support base 1, two grinding rollers 3 attached side by side are arranged in the grinding box 2, two scraping plates 4 are arranged on the upper side and the lower side of each grinding roller 3, the scraping plates 4 are made of spring steel plates with the thickness of 1mm, one end of each scraping plate 4 is abutted to the grinding rollers 3, the other end of each scraping plate is fixed to the inner wall of the grinding box 2, a feeding hole 5 is formed in the top of the grinding box 2, a sealing cover 6 connected with threads is arranged on the feeding hole 5, a first driving mechanism connected with one of the grinding rollers 3 is arranged on the outer side of the grinding box 2, and a second driving mechanism used for driving the grinding box 2 to rotate is arranged on the outer side.

The two sides of the fixed bracket base 1 are both provided with supporting arms 11, and the two sides of the grinding box 2 are both provided with first rotating shafts 21 penetrating through the corresponding supporting arms 11.

The grinding box 2 is in a cube shape, the top plate of the grinding box 2 is in a spherical surface shape bulging outwards, and the feeding hole 5 is located in the middle of the top plate of the grinding box 2.

And two ends of the grinding roller 3 are respectively provided with a second rotating shaft 31 penetrating through the side plate of the grinding box 2, and the first driving mechanism is connected with any one second rotating shaft 31.

The first driving mechanism comprises a first motor 71 fixed with the grinding box 2, the output end of the first motor 71 is provided with a first driving wheel 72, the first driving wheel 72 is connected with a second driven wheel 74 through a first transmission belt 73, and the second driven wheel 74 is connected with the second rotating shaft 31.
