Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate processing, in particular to a pulverizer for calcium carbonate production. Background Art

[0002] Calcium carbonate is an inorganic compound, commonly known as graystone, limestone, stone powder, marble, etc. Calcium carbonate is neutral, basically insoluble in water, and soluble in hydrochloric acid. It is one of the common substances on the earth and exists in rocks such as aragonite, calcite, chalk, limestone, marble, travertine, etc. It is also the main component of animal bones or shells. In the production process, a crushing device is required to crush the calcium carbonate raw materials.

[0003] The Chinese patent application number 202120013526.9 discloses a pulverizing device for producing calcium carbonate powder, which belongs to the technical field of calcium carbonate production, and includes a box body, a pulverizing roller A is installed on one side of the box body, and a pulverizing roller B is installed on the other side of the box body. A filter plate A is fixedly connected to the bottom of the pulverizing roller A at an angle, and a filter plate B is fixedly connected to the bottom of the pulverizing roller B at an angle. A collecting box B is installed on one side of the bottom of the filter plate B, and a feed hopper is fixedly connected to the top of the box body. The pulverizing roller A pulverizes the calcium carbonate, and the materials that meet the requirements directly pass through the filter plate A, and the rest continue to fall between the pulverizing rollers B for secondary pulverization. The materials after secondary pulverization fall The materials that meet the requirements and pass through the filter plates A and B are discharged into the collecting box A for collection, while the materials that do not meet the requirements slide into the collecting box B, which is convenient for taking out for subsequent re-crushing, thereby improving the crushing quality and effect of the materials. However, there are still some deficiencies in the implementation of this patent. During the process of crushing calcium carbonate, this patent cannot automatically transport the unqualified calcium carbonate raw materials that have been screened to the crushing knife for re-crushing. It is necessary to manually pour the unqualified calcium carbonate raw materials that have been screened back into the crusher for re-crushing, thereby wasting a lot of crushing time and resulting in low crushing efficiency of the crusher for calcium carbonate.
