Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, and specifically to a ball milling device for ore dressing. Background Art

[0002] In the field of mineral resource development, ball mills are important equipment for ore crushing and grinding. Crushing and grinding are beneficial to subsequent ore dressing operations. The ore dressing process is a key link to effectively separate useful minerals from useless minerals in ore. There are many types of ball mills on the market, and most of them have the advantages of high efficiency and portability.

[0003] However, when the ball mills on the market are in use, there is no corresponding dust removal component on them, and dust removal operations cannot be realized. Since the ball mill drives the rotation and crushing of ore during operation, dust will be generated during this process. The dust will be discharged outward from the discharge hole of the ball mill. The dust floating in the air will pollute the environment, and the dust is also harmful to the human body, bringing inconvenience to users. In view of this, we have proposed a ball milling device for ore dressing. Summary of the Utility Model
