Description

Technical Field

[0001] The utility model relates to the field of ball mills, in particular to a negative pressure continuous discharging ball mill. Background Art

[0002] Negative pressure continuous discharge ball mill is a special type of ball mill, and its working principle is similar to that of conventional ball mill, but it is different in the discharge method. It realizes continuous discharge through a negative pressure system, which can effectively control dust pollution and improve production efficiency. Specifically, when the negative pressure continuous discharge ball mill is working, its internal container (usually a rotating cylinder) rotates, so that the abrasive (such as steel balls) and the material to be ground rotate together. During the rotation process, the abrasive is subjected to the action of centrifugal force, collides and rubs with the material to be ground, thereby crushing and grinding the material. The negative pressure discharge mechanism forms a negative pressure environment at the discharge port, so that the ground material can be discharged continuously and stably. When the existing negative pressure continuous discharge ball mill is working, the abrasive is subjected to the action of inertia and centrifugal force, and the collision and grinding of the material will make noise. The existing ball mill does not have a noise reduction function, which makes the working environment noisy and affects the health of workers. Therefore, those skilled in the art provide a negative pressure continuous discharge ball mill to solve the problems raised in the above background technology. Utility Model Content
