Abstract
The utility model discloses a superfine-powder calcium carbonate grinder, which comprises a cylindrical housing, a stirring device driven by a power device is arranged in the cylindrical housing, the upper portion of the cylindrical housing is provided with a feeding port, and the side wall of the lower portion of the cylindrical housing is provided with a slurry discharging port and a grinding medium discharging port. The superfine-powder calcium carbonate grinder realizes mechanical and automatic production of the whole grinding process, reduces manual work and labor intensity, and increases production efficiency.
Description
Technical field
The utility model relates to superfine powder calcium carbonate production equipment technical field, specifically, relates to a kind of superfine powder calcium carbonate grinder that oarse-grained raw material is ground to form ultra-fine grain.
Background technology
The calcium carbonate of ultra-fine grain is of many uses, can be used for industries such as papermaking, plastics, rubber.Superfine powder calcium carbonate can replace china clay fully as the filler and the coating pigment of paper grade (stock), reduces the papermaking cost greatly, and can improve strength of paper and smoothness, improves the printing quality and the print gloss of paper printing ink uniform absorption and paper.The particle diameter of the superfine powder calcium carbonate slurry that the paper mill is used requires below 2 microns, and the selected raw material of superfine powder calcium carbonate slurry factory are the meal marble breeze of 325 orders (45 microns).Aborning, 325 purpose bulky grain meal marble breezes satisfactory ultra-fine grain Paris white below 2 microns need be ground to, just paper production can be used for.
The utility model content
Technical problem to be solved in the utility model is: a kind of superfine powder calcium carbonate grinder that oarse-grained raw material is ground to form ultra-fine grain is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: superfine powder calcium carbonate grinder, comprise cylindrical shell, be provided with the agitating device that drives by power set in the described cylindrical shell, the top of described cylindrical shell is provided with the slurry import, and the sidewall of described cylindrical shell bottom is provided with slurry outlet and abrasive media outlet.
As optimized technical scheme, described agitating device comprises the rotating shaft that vertically is arranged in the described cylindrical shell, and described rotating shaft is provided with some along its grinding rod that radially extends.
As optimized technical scheme, described power set comprise the motor that is arranged on described cylindrical shell top, and the reduction box that is connected with the output of described motor, and the output of described reduction box is connected with described rotating shaft.
As optimized technical scheme, described reduction box is provided with temperature sensor, and described reduction box also is connected with an oil cooler.
Owing to adopted technique scheme, the beneficial effects of the utility model are: superfine powder calcium carbonate grinder of the present utility model is installed in series by many grinders usually and forms a grinding production line in use.The oarse-grained slurry that last process has prepared joins in the cylindrical shell from the slurry import on cylindrical shell top, abrasive media is selected ceramic bead usually for use, also join in the cylindrical shell, in cylindrical shell, power set drive agitating device slurry are stirred, under the effect of the grinding-aid dispersant in slurry, high velocity impact between abrasive media and the calcium carbonate granule and shear action have reduced the foot cun of calcium carbonate granule, make these particles become more and more thinner, and in process of lapping, can and shear because of friction and produce heat, can promote the temperature and the solid content of slurry, dispersant can reduce the viscosity of slurry, improves its flowability.The slurry outlet of slurry on the cylindrical shell lower sides after first grinder grinds delivered to follow-up grinder through delivery pump and continued to grind, the particle diameter of the calcium carbonate slurry that last grinder grinds out reaches desired micron order promptly less than after 2 microns, will enter next workshop section and sieve processing.Whole process of lapping has been realized mechanization, automated production, has reduced manually-operated, has reduced labour intensity, has improved production efficiency.
