DETAILED INTRODUCTION
Product Introduction
The mill is an important equipment in the grinding process, mainly used for grinding materials to obtain the particle size products required by the process. It is widely used in industries such as power, black (non-ferrous) metals and non-metallic mineral processing, chemical industry, building materials, etc.
According to the different grinding media loaded, it can be divided into ball mill (Ball Mi1), rod mill (Rod Mi) and self-mill without loading media (AG Mi). According to the discharge method, it can be classified as: wet type, dry type and overflow type. According to the transmission form, it can be divided into edge transmission and center transmission. The former is more commonly used. According to the driving form, it can be divided into:
a. Asynchronous motor drive: asynchronous motor + reducer + small gear + large gear.
b. Synchronous motor drive: synchronous motor + air clutch + small gear +large gear.
c.Asynchronous motor +reducer + diaphragm coupling.
The main bearings of the mill can adopt sliding bearings, rolling bearings and sliding shoe bearings, etc.
The mill liner can adopt wear-resistant metal liner, rubber liner, magnetic liner and aluminum oxide liner (i.e.,high-aluminum lining brick).
According to the needs, a slow drive device, high and low pressure lubrication station, automatic lubrication device for transmission gears, lifting device and PLC control system can be equipped.

Working Principle
During operation, the ball mill receives torque from the electric motor and reducer, which is transmitted to the mill’s large and small gears, thereby rotating the mill shell. As the shell rotates, the steel balls (or other grinding media) inside are lifted to a certain height by the corrugated lining plates and then fall freely, striking the material in the mill. Simultaneously, the grinding media, thoroughly mixed with the material, continuously collide with and grind the material as the shell turns.
A ball mill primarily consists of a cylindrical shell, end caps, bearings, and a large gear ring for transmission. The shell is filled with steel balls or steel rods ranging in diameter from 25 to 150 mm, with the filling level accounting for 25% to 50% of the shell’s effective volume. Each end of the shell is fitted with an end cap, which is bolted to the corresponding flange at the shell end; the center of each end cap features a hollow shaft journal that rests on the bearing, allowing the shell to rotate. A large gear ring is also securely mounted on the shell. In the drive system, an electric motor, via a coupling, a reducer, and a pinion gear, drives the large gear ring and the shell to rotate slowly. As the shell turns, the grinding media rise along the inner wall to a certain height before falling in a parabolic arc or cascading down. Because the end caps are equipped with hollow shaft journals, material is fed into the shell through the central opening in the inlet-end journal and gradually spreads and moves toward the discharge end. During this forward movement, the rotating shell lifts the steel balls to a certain height, where they fall and crush the material; meanwhile, some of the balls cascade down within the shell, exerting a grinding action on the material. Thus, the entire conveying process simultaneously constitutes the crushing of the material.
