Abstract
The invention provides a production process of multifunctional calcium carbonate. The method comprises the steps of: grinding a calcium carbonate raw material, and then conducting classification on the ground calcium carbonate; conducting at least one classification on the calcium carbonate less than a first grain size to obtain calcium carbonate in different particle size ranges; and subjecting the calcium carbonate larger than the first particle size to a wet grinding In the invention, the production process is optimized; and ground calcium carbonate is subjected to multiple classification treatments to avoid the over-grinding phenomenon in calcium carbonate production, and realize large-scale production of multifunctional calcium carbonate, thereby reducing energy consumption, saving resources and lowering production costs.
Description
Technical field
The present invention relates to the calcium carbonate production technical field, relate in particular to a kind of production technique of multifunctional calcium carbonate.
Background technology
In industrial application, the size of calcium carbonate has determined the function of calcium carbonate.In the prior art, in the production process of calcium carbonate, in order to obtain the calcium carbonate granule of different-grain diameter, with the calcium carbonate raw material in shredder constantly, grind repeatedly, and, can decide by the control milling time distribution of size, then the calcium carbonate after grinding be carried out stage treatment, obtain the calcium carbonate granule of different-grain diameter.In the process that calcium carbonate is ground repeatedly, there was grinding phenomenon in calcium carbonate, for example, the size distribution of calcium carbonate is 600 orders, 2000 orders and 3000 orders in process of lapping, in continuing process of lapping, 2000 orders and 3000 purpose calcium carbonate will repeat to grind, and cause the calcium carbonate of this particle diameter to occur grinding; Mistake grinding phenomenon in the calcium carbonate production process is difficult to realize the large-scale production of multifunctional calcium carbonate, and has strengthened production energy consumption, has wasted resource, has improved the production cost of calcium carbonate.
Therefore, how the production technique of calcium carbonate is improved, avoid the mistake grinding phenomenon of calcium carbonate in producing by the optimized production process flow process, thereby reach the reduction production energy consumption, economize on resources, reduce the purpose of the production cost of calcium carbonate, become those skilled in the art's technical problem in the urgent need to address.
Summary of the invention
Technical problem for the background technology existence; the present invention proposes a kind of production technique of multifunctional calcium carbonate; can avoid the mistake grinding phenomenon of calcium carbonate in producing by the optimized production process flow process; realized the large-scale production of multifunctional calcium carbonate; thereby reduced production energy consumption, saved resource, reduced production cost.
The present invention proposes a kind of production technique of multifunctional calcium carbonate, comprising:
The calcium carbonate raw material is ground, then the calcium carbonate after grinding is carried out scalping;
For the calcium carbonate less than the first particle diameter, carry out again at least scalping, obtain the calcium carbonate in the different-grain diameter scope;
Carry out wet grinding for the calcium carbonate greater than the first particle diameter.
Preferably, described the first particle diameter is 1000 orders, for carrying out secondary grading less than 1000 purpose calcium carbonate, obtains less than 2000 purpose calcium carbonate after the scalping again.
Preferably, for carrying out again three classifications less than 2000 purpose calcium carbonate, obtain less than 3000 purpose calcium carbonate after the secondary grading.
Preferably, in the wet grinding machine, carrying out wet grinding greater than 1000 purpose calcium carbonate, must beat 5000-6000 purpose calcium carbonate after the scalping.
Preferably, after wet grinding, calcium carbonate is carried out dry modification, then carry out pulverization process.
Preferably, the calcium carbonate raw material is also comprised before grinding: the calcium carbonate raw ore is just broken through horizontal crusher again after the jaw crusher fragmentation, just broken after the particle diameter of calcium carbonate in 15 millimeters.
In the present invention; by the optimized production process flow process; calcium carbonate is carried out multiple fractionation after grinding to be processed; avoided the mistake grinding phenomenon in the calcium carbonate production; realized the large-scale production of multifunctional calcium carbonate; reduce production energy consumption, saved resource, reduced the production cost of calcium carbonate.
