Types of Ball Mills

There are many specific types of ball mills, the difference lies in the

loading of grinding media, discharge method, transmission and support mode. Various types of ball mill grinder can be mainly classified in this way.

According to the Different Grinding Media

1.   Ball mill: the steel ball or steel segment is installed in the barrel, which is the most commonly used grinding mill.

2.   Rod mill: The steel rod in the cylinder is used as the grinding medium, which is generally suitable for the rough grinding stage. The particle    size of rod mill products is relatively uniform.

According to the Discharge Method

1.  Central discharge: The discharge port of the ball mill machine is

located at the central shaft hole of the ball mill, and it can be divided into two types.

a.  Overflow type central discharge ball mill: when the ball mill

machine is grinding, the material surface in the mill must be higher than the discharge port, so that the material overflows. The overflowing ball mill has a large grinding body load and a simple internal structure.

b.  Grid type discharge ball mill: in order to overcome the defects of   overflow ball mill, grid type lifting plate is added at the micro end  of ball mill to help discharge, so it becomes grid type ball mill. The grid type ball mill are mostly used in cement plants.

2.   Peripheral discharge: This ball mill grinder discharges through the

peripheral wall of the barrel. The peripheral discharge ball mill grinder  has compact equipment, material saving and high unit power capacity. As a new type of ball mill grinder, it is mostly used in the circulation

system with powder separator.

According to the Transmission Mode

1.  Center drive ball mill machine. The discharge end is directly

connected with the output shaft of the reducer through the hollow     shaft, driven by the motor, and the center of the transmission shaft is consistent with the center line of the barrel.

2.   Edge drive ball mill machine. The rotating device of the ball mill

transfers the power of the motor through the reducer to the rotating shaft which is parallel to the center line of the ball mill barrel. The

gear on the shaft drives the big gear installed on the ball mill barrel to make the ball mill rotate.

3.   Friction drive ball mill machine. This kind of ball mill belongs to a

special edge drive ball mill machine. It is driven by the friction

between the wheel belt mounted on the cylinder and the tug on the main shaft.

In addition to the classification of ball mills in the above ways, bearing   support and idler support, or the combination of the two supports, etc. can also be used according to the support ways.
