[0001] The utility model relates to the technical field of calcium carbonate powder production, in particular to calcium carbonate powder production equipment. Background Art

[0002] Calcium carbonate powder is a white powdery inorganic compound. It is a naturally occurring mineral whose main component is calcium carbonate. It mainly comes from limestone, dolomite and shells. The production equipment of calcium carbonate powder is mainly used to convert calcium carbonate raw materials into calcium carbonate powder.

[0003] In traditional calcium carbonate powder production equipment, there is a problem that the raw materials cannot be tumbled and heated. During the production process, the mined raw materials are directly placed in the equipment, but some of the raw materials will have moisture attached to the surface. If production is carried out directly, the calcium carbonate powder will have problems such as agglomeration and crystallization, affecting the performance of the product. If the wet raw materials are processed for a long time, it may also cause corrosion and blockage of the equipment. In addition, the traditional calcium carbonate powder production equipment also has the problem of being unable to screen the calcium carbonate powder. Without the screening process, the product may contain particles of different coarseness and fineness. The uneven particle size distribution will affect the performance and quality stability of the product, and more impurity particles will be mixed into the final product. Excessive impurity content will reduce the purity and use value of the product. Utility Model Content
