The Application of Ball Mill in Mineral Processing Equipment

There are many mineral processing equipment, ball mill is an indispensable equipment in the mineral processing operations, and occupies a place in the market. Ball mill can be grinding of dry or wet grinding for all kinds of ores and other materials. It is widely used in cement, silicate products, new building materials, refractories, fertilizers, black and nonferrous metal processing and glass ceramics and other production industries.
In order to separate the gangue minerals in the ore and separate the various useful minerals from each other, it is necessary to separate the minerals from the individual. Mineral separation of the individual is difficult to achieve with the broken method. Because the mineral contamination is often not uniform, grain size of a few millimeters of mineral particles and a few microns of particles are present. Therefore, in order to make the mineral to separate the monomer, the usage of grinding method, the ore grinding to the sorting operations required particle size is the best way, so that grinding operations is one of the key operations in the concentrator production.
Ball mill at work, because the steel ball is squeezed in the cylinder and the adjacent steel ball in the middle, so the force will make the ball the size of the friction and the size of the ball with the cylinder axis for the revolution. In the region from the drop down, in the region on the cylinder of the ore to produce a strong impact, the ore broken. In other words, the ore in the ball mill cylinder is mainly by the grinding force, impact force and the role of squeezing force is ground.
When the ball mill is working, the material is loaded into the cylinder by the feed end hollow shaft. When the ball mill cylinder rotates, the grinding body acts on the cylinder liner by the inertia and centrifugal force and the friction force. Take away, when brought to a certain height, due to their own role in the gravity is thrown, the falling body like the projectile body of the barrel of the material to crush. The material is then fed into the first bin of the ball mill by means of the feed unit via the feed hollow shaft, which has a ladder liner or corrugated liner and a variety of gauge steel balls. The cylinder rotates to produce a centrifugal force to bring the ball to a certain height after the fall, the material hit and grinding effect. Material in the first warehouse to reach rough grinding, the single compartment through the plate into the second warehouse, the warehouse is set with a flat liner, there are steel balls, the material further grinding. The powder is discharged through the discharge grate to complete the grinding operation.
