Embodiment 1
[0027] Select coarse calcium carbonate with a particle size of less than 1 cm for crushing, add water and grinding dispersant at the same time during the crushing process, and control the mass-volume ratio of the feed calcium carbonate, water, and grinding dispersant to about 1:10:0.5, where , the grinding dispersant, in parts by mass, 0.5 parts of borate coupling agent, 5 parts of hydroxymethyl cellulose, 5 parts of tributyl phosphate, 5 parts of ferric oxide, 5 parts of ethylene glycol .
[0028] The grinding device includes a material crushing box 1 and a grinding box 11, and the two are connected by a connecting channel 6. The upper end of the material crushing box 1 is provided with a feed port 5 to facilitate the insertion of materials. A speed governor 16 is provided, and the inner position of the speed governor 16 is respectively connected with three crushing rotating rods 17 to crush the material. Both sides of the material crushing box 1 are equipped with a starter m...
Embodiment 2
[0030] Select coarse calcium carbonate with a particle size of less than 1 cm for crushing, add water and grinding dispersant at the same time during the crushing process, and control the mass-volume ratio of the feed calcium carbonate, water, and grinding dispersant to about 1:10:0.5, where , the grinding dispersant, in parts by mass, 2 parts of borate coupling agent, 3 parts of hydroxymethyl cellulose, 10 parts of tributyl phosphate, 10 parts of ferric oxide, 8 parts of ethylene glycol .
[0031] The above-mentioned materials are fed through the feed port 5, and the materials are added into the material crushing box 1 through the funnel 4 to prevent the entrance of the material crushing box 1 from being damaged. The speed governor 16 drives the crushing rotating rod 17 to rotate to crush the materials processing, the crushed material is transported on the conveyor belt 15, and is transported to the isolation box 20 in the grinding box 11 through the transmission channel 6.
