Description

Technical Field

[0001] The utility model belongs to the technical field of calcium carbonate processing, in particular to a production device for ultra-fine grinding calcium carbonate powder. Background Art

[0002] Calcium carbonate is an inorganic compound with the chemical formula CaCO3. It is the main component of limestone, marble, etc. Calcium carbonate is usually white crystals, odorless, basically insoluble in water, and easily reacts with acids to release carbon dioxide. It is one of the most common substances on Earth and exists in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of the bones or shells of some animals. Calcium carbonate is also an important building material and has a wide range of industrial uses.

[0003] However, some calcium carbonate crushing devices use two flat rollers to rotate and roll on the bottom plate to squeeze the calcium carbonate particles into powder. This method may easily result in some of the raw materials falling from above not falling into the contact surface between the two rollers and the bottom plate. Some of the incompletely crushed raw materials fall directly from the uncontacted discharge port under the drive of the rollers, resulting in some unqualified calcium carbonate raw materials being mixed into the food raw materials. The incomplete crushing reduces the qualified rate of raw material grinding. Utility Model Content
