Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a spring cone crusher for superfine crushing. Background Art

[0002] When the stone is put into the feed port of the crusher, due to the height difference, a lot of dust will be generated when the stone contacts the crusher, and the crusher will also generate a lot of dust when it is working. During production operations, if the dust cannot be effectively handled, it will float in the air. The crusher is generally located at a higher position, which can easily cause dust to float indiscriminately in the workplace and pollute the office space.

[0003] Therefore, the present application provides a spring cone crusher for ultra-fine crushing to meet the demand. Utility Model Content
