description for rock grinder for sale QMJ2200x7500

The ball mill is the key equipment after the crushing process of the concentrator, which is used to grind various materials such as copper ore, gold ore, magnetite, quartz, lead-zinc ore into 20-75 micron fine powder. According to the discharge type, it can be grate type, overflow type, etc. In addition, the ball mill can be used for dry and wet grinding of various ores and other grindable materials.

Ball mill is a kind of grinder used to grind materials into very fine powder, mainly used in mineral processing industry. The ball mill can wet mill or dry mill various ores and other materials according to requirements. The ball mill is composed of a large cylinder rotating slowly around a horizontal axis. The cylindrical part is filled with the material to be ground and the grinding medium (metal grinding ball). In the cylinder, the medium will be lifted to a certain height under the action of centrifugal force, and then fall. When they interact with each other, the ore will be ground between the balls. The feed to be ground enters the cylinder through a hopper at one end, and is discharged at the other end after being crushed by the grinding medium.

working principle for rock grinder for sale QMJ2200x7500

The ball mill is omitted from the external gear. The materials are uniformly transported to the grinding chamber through the spindle. The chamber is provided with step liner, corrugated liner and steel balls of different specifications. The centrifugal force generated by the rotation of the cylinder will bring the steel ball to a certain height, impact and grind the material. The grinding material is discharged through the discharge plate to complete the grinding process.

The ball mill is a horizontal cylindrical rotating device, driven by edge gears, and has two chambers and grids. The material enters the first chamber through the feed port. In the first chamber, there are grade liners, corrugated liners and various steel balls. The rotation of the shell generates eccentricity, which brings the ball to a certain height, and then the ball falls under the action of gravity, which will impact and grind the material. After one grinding in the first chamber, the material enters the second chamber through the isolation screen. In the second chamber, there are flat liners and steel balls. After the second grinding, the material is discharged through the discharge screen.
