Industrial calcium carbonate preparation process

Abstract

The invention relates to an industrial calcium carbonate preparation process. The industrial calcium carbonate preparation process adopts the following industrial calcium carbonate preparation device, wherein the industrial calcium carbonate preparation device comprises a base, U-shaped frames, a stirring and drying mechanism, a grinding and filtering mechanism and a transmission mechanism; the U-shaped frames of a U-shaped structure are symmetrically arranged on the right side of the upper end face of the base front and back; a stirring and drying mechanism and a grinding and filtering mechanism are sequentially arranged between the U-shaped frames from top to bottom, and a conveying mechanism is arranged on the portion, located between the U-shaped frames, of the upper end face of the base. The invention can solve the problems that in the drying and grinding process of industrial calcium carbonate in the prior art, due to the fact that limestone particles are not stirred and turned over during drying, the limestone particles on the lower layer are difficult to dry completely, and the drying effect on the industrial calcium carbonate is reduced; besides, the process of transferring the dried industrial calcium carbonate to a grinding machine is long, so that the grinding efficiency of the industrial calcium carbonate is influenced.

Description

Technical field [0001] The present invention relates to the field of calcium carbonate, and more particularly to an industrial calcium carbonate preparation process. Background technique [0002] Calcium carbonate is a kind of inorganic compound, commonly known as gray stone, limestone, stone powder, marble, etc .; one of the common substances on the earth, existing in the rock, marble, limestone, etc., is also an animal bone Or the main component of the outer casing. Calcium carbonate is also an important building material. The industrial use is widely used, and the industrial carbonate is usually used as raw materials, and then the limestone raw materials are pulverized. Prior art will often add water to limestone when pulverizing limestone. However, when the watery is wet, the pulverized limestone particle powder is easily agglomerated, and the amount of limestone particles after adding water is different, so it is especially important for drying of the limestone particle powd...

AI Technical Summary

Problems solved by technology

[0004] 1. In the prior art, when the limestone particles are dried, it is difficult to completely dry the limestone particles in the lower layer because the limestone particles cannot be stirred and turned, thereby reducing the effect of drying the limestone particles;

[0005] 2. It takes a long time to transfer the dried limestone particles to the grinding machine, which affects the efficiency of grinding limestone particles, and manufacturers usually need to have drying machinery and grinding machinery to be able to sequentially grind limestone particles Drying and grinding, which increases the cost of purchasing and maintaining manufacturing equipment for manufacturers
