Ball mill is the key equipment for crushing materials after being crushed, so it is widely used in mineral processing, building materials and chemical industries.
What is the ball milling process? Although ball milling equipment is frequently used, many users are still curious about it. Therefore, in order to better help users use the ball mill, the specific working principle of the ball mill is introduced as follows:
The ball milling process is generally divided into two types, the dry ball milling process, and the wet ball milling process. This article takes dry ball milling as an example to introduce the ball milling process.
First, select the appropriate size and weight of the grinding medium according to the particle size of the grinding material. The material is loaded into the cylinder by the hollow shaft at the feed end of the ball mill machine. When the cylinder of the ball mill rotates, the grinding body is attached to the liner of the cylinder and taken away by the cylinder due to the action of inertia, centrifugal force, and friction. When brought to a certain height, it will be thrown down due to its own gravity, and the falling grinding body will crush the material in the cylinder like a projectile.
The materials are evenly fed into the grinding bin of the first bin of the ball mill through the feeding device through the feeding hollow shaft screw. There are stepped lining plates or corrugated lining plates in the bin, which are filled with various specifications of steel balls. The centrifugal force produced by the rotation of the cylinder will bring the steel ball to a certain height and then fall down, resulting in heavy impact and grinding on the material. After rough grinding in the first grinding bin, the material enters the second grinding bin through a single-layer partition board. The bin is inlaid with a flat-lining plate and steel balls, which will further grind the material. The powder is discharged through the discharging grate plate to complete the dry ball milling process.
A deeper understanding of the grinding process of ball mill can better grind materials, promote the use efficiency and performance of ball mill, effectively reduce equipment damage and prolong service life.
