[0001] The utility model relates to the technical field of gypsum powder production, in particular to a column mill. Background Art

[0002] Column mill is the most widely used vertical mill at present. It is mainly used in the ultra-fine crushing of iron ore and metal ore, pre-grinding of cement slag, gypsum, non-metallic ore powder making, phosphate rock, gold mine, silver mine and other non-ferrous metal industries. The main role of column mill in the preparation of gypsum powder is to crush the pre-crushed raw materials into finer pieces. The current common column mill adopts a mechanism that sets a rotating roller in a confined space, and grinds and crushes the fed material through its rotation.

[0003] However, most of the existing column mills have a simple structure, and generally have a single grinding structure inside. This will result in incomplete grinding, and gypsum powder will be missed from the corners of the grinding mechanism. The overall structure of the grinding mechanism is relatively simple, and it mainly relies on the characteristics of the materials used in the equipment to achieve the desired effect. However, in actual use, there is still the defect of incomplete crushing. Utility Model Content
