Abstract

The invention relates to the field of milling and discloses a ball mill. The ball mill comprises a barrel (10) capable of rotating and a feeding hole (11) and a discharging hole (12) formed in the barrel (10). The ball mill is characterized by further comprising a steel ball adding device which comprises a steel ball adding pipeline (21) and a supporting frame (22), wherein the steel ball adding pipeline (21) extends into the barrel (10) from the discharging hole (12) and the supporting frame (22) is used for supporting and fixing the steel ball adding pipeline (21). When steel balls are added, the ball mill provided by the invention does not need to stop running and a manhole does not need to be opened, so that the problem of increasing risk in work high above the ground caused by frequently detaching the manhole is solved. That is to say, the steel balls can be added into the barrel of the ball mill in the running state of the ball mill, the operation is easy and convenient and the ball mill is safe and practical.

Description

technical field [0001] The invention relates to the field of grinding, in particular to a ball mill. Background technique [0002] In the desulfurized limestone slurry preparation system, the ball mill is an indispensable equipment. Generally, the ball mill includes a rotatable cylinder and a feed inlet and a discharge outlet arranged on the cylinder. The cylinder passes through a bearing (such as a rolling bearing). )support. The grinding of materials by the ball mill is actually achieved by steel balls. Specifically, steel balls are added to the barrel of the ball mill, and the grinding and peeling effect is generated through the collision and friction between the steel balls and the steel balls and the steel balls and the materials (such as limestone). , so as to grind the material. For example, limestone is ground by adding water in the cylinder. After grinding, the qualified limestone slurry is separated and screened through the cyclone station, and the unqualified li...
