Description
Technical Field
The utility model belongs to the technical field of the technique of screening machinery is smashed to the ore and specifically relates to a magnetism welt formula ball mill is related to.
Background
The ball mill is widely applied to the grinding operation of metal and nonmetal selecting factories, cement factories and industries of refractory materials, ceramics, electric power and the like, and is key equipment in the mine grinding process. The main working components in the ball mill are lining plates and ore grinding media, and the impact and abrasion of the ore grinding media and ores on the lining of the ball mill make the lining plate of the ball mill become one of main consumed materials in the operation of the ball mill, so the quality and the performance of the lining plate directly influence the quality of ore grinding and the service life of the ball mill.
The current mineral separation process mostly uses three ball mills connected in series in sequence to reduce the granularity of ore in sequence, and because the ore has large granularity when entering the first-stage ball mill and the diameter of the steel ball used for grinding is also large, the impact force of the ore and the steel ball on the inner wall of the ball mill is large during grinding, so that the magnetic lining plate of the ball mill is only suitable for the two-stage and three-stage ball mills for mineral separation in order to avoid the magnetic lining plate from being damaged by impact.
The ball mill can be roughly classified into a turnover state, a sliding state, and a falling state during grinding. The steel ball is in a turnover state when synchronously rotating along with the cylinder, at the moment, the centrifugal force enables the steel ball to rotate along with the cylinder, the whole steel ball forms a circular ring tightly attached to the inner wall of the cylinder, the turnover state is called, and the grinding medium cannot impact and grind materials. The steel ball moves to a certain height along the cylinder and then rolls along the inner wall of the cylinder, which is called as a 'slip state', the steel ball has a grinding effect on the materials, but has no impact effect on the materials, so that the grinding efficiency is poor. After the steel ball is lifted to a certain height along the cylinder body, the steel ball leaves the circular track and falls along the parabolic track in a free-falling mode, namely a 'falling state', and the steel ball falling along the parabolic track has impact and grinding effects on the steel ball at the lower part of the cylinder body or a lining plate of the cylinder body, so that the materials are crushed.
