Description

Technical Field

[0001] The utility model relates to the technical field of limestone processing, and more specifically, to a Raymond mill for limestone processing. Background Art

[0002] Raymond mill is a kind of equipment commonly used in limestone processing. Raymond mill, also known as Raymond mill, Raymond grinding mill, is manufactured by Raymond grinding mill manufacturers. It is the most widely used type of modern mining equipment. Raymond mill puts limestone and other raw materials into the grinding mill, and grinds, crushes, and grinds them into the required powder.

[0003] However, in actual use, there are still certain problems. For example, when grinding limestone, the limestone is poured directly into the feed port. Since a large amount of dust will overflow when the limestone is poured, the dust will be directly dispersed into the air and the inside of the machine. The workers need to wear appropriate protective equipment to prevent the inhalation of dust. Therefore, when transporting and dumping the limestone, they must wear the appropriate equipment in advance and will be inconvenient to move due to the equipment, which will affect the grinding of the limestone and the subsequent processing progress. Utility Model Content
