Ball Mill

Introduction to ball mill

It is widely used in cement and silicate products; new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other mineral production industries of all kinds of ores and other grind-able materials can be dry or wet grinding. According to different ways of discharge it can be divided into two kinds of lattice type and overflow type.

How ball mill works

Cylindrical ball mill is a horizontal rotating device. Material will be fed evenly into the first warehouse where has ladder liner or corrugated liner, built with different specifications of steel balls; centrifugal force will raise the ball to a certain height. After the falling, the material will be seriously impacted and abraded. The material will then enter the second silo which is lined with flat liner for further grinding.

The steps in detail when problems happen in running the ball mill

When the ball mill is running, there is regular beating noise. The temperature of ball mill and reducer is high. When ball mill reducer is driving, there will be a huge vibration. When the ball mill reducer is running, the sound is unusual.

For the common problems in operation, in order to resolve these issues better we should adopt different solutions according to different reasons.

Match of ball diameter is very important: pay attention to the size of ball diameter, which can improve efficiency.

Change the formula is to increase the strength and weight of the ball (to increase its inertia).Grinding time and efficiency have no relationship, because efficiency itself is the ratio of effort and time.

Methods of increasing speed include the use of inverters and modified deceleration device (if there is deceleration device).

Then there is a must to add water during milling time. Also, dispersant can be added to improve the milling efficiency.
