A cement ball mill is a tube grinding machine that used to grind materials into a fine powder. Cement ball mill stands as the key equipment for cement grinding, serving a pivotal role in cement production plants and cement grinding stations. However, its applications extend far beyond, encompassing a diverse range of materials. It is extensively used in industries such as cement production, metallurgy, chemical, and others. The material to be ground is fed from the feed end into the rotating drum or shell of the ball mill, along with steel or ceramic balls. The rotation of the drum causes the balls to cascade and grind the material, reducing it to the desired fineness. Tongli emerges as the trusted and professional ball mill supplier, delivering an extensive array of top-tier ball mills.

Tongli cement ball mill features long service life, low maintenance cost with over 65 years of pioneering technical innovation in ball mill design. Tongli seamlessly integrates technological expertise, core manufacturing finesse, cutting-edge solutions and meticulous quality control into our TL series ball mills.
The main components of the ball mill include the mill shell, trunnion, slide shoe bearing, liners, diaphragm, grinding media, transmission device and so on. Depends on the transmission method, if the ball mill is edge drive, then it will have girth gear and pinion.
Mill Shell: The foundation of the ball mill, the mill shell, is a sturdy cylindrical structure crafted from premium-grade steel. This robust shell encases the grinding process, confining it within a controlled environment. Tongli heavy machinery is equipped with a large annealing furnace of 6.5x6.5x20m and a 6.5x6.5x20m large sandblasting room, which can conduct overall heat treatment and sandblasting on the ball mill to ensure the service life and appearance of the ball mill.Trunnion: The trunnion (hollow shaft) of the ball mill is a key part of the cement machinery, which is a special type of steel casting. It mainly plays the role of supporting and connecting the cylinder in the weight of the whole machine, and is the passage for the material to enter and exit.
Bearing Bush: Ball mill bearing bush ensures the smooth rotation of the ball mill and empowers the ball mill to maintain optimal grinding conditions. It is equipped with a forced lubrication system and also cooling system.
Transmission connection: Tongli’s ball mill is equipped with a transmission connection, which is welded on the cylinder and machined together with the ball mill shell to avoid assembly errors and ensure the concentricity of the ball mill.Girth Gear: The cement ball mill girth gear is a large gear ring encircling the ball mill, usually mounted on the shell of the ball mill. It is driven by a pinion gear, and together they form the primary drive unit to rotate the ball mill. The girth gear is casted and machined Tongli, the quality is assured.
Hood Cover: The discharge hood of the ball mill is installed at the discharge end of the ball mill, and there is a screen inside. After grinding, the material with a qualified size will enter the discharge hood through the screen and enter the next process. There is a vent on the upper part of the discharge hood, and a discharge funnel on the lower part.
Diaphragm: The ball mill Diaphragm (compartment plate) is fan-shaped plate or bow-shaped grate plate fixed in the ball mill with bolts. Its function is to divide the ball mill into two or more chambers, the material moves to the next compartment through the holes on the grate plate. The function of the compartment plate is to prevent the grinding media running from one compartment to another compartment, so that the materials can be reasonably finely ground.
Liner: The function of the liner is to protect the shell of the ball mill and the trunnion, some special-shaped liners can also design to lift the grinding media to a certain position. According to the shape of the liner, it can be divided into flat liner, beaded liner, corrugated liner, ribbed liner, stepped liner, etc.
Cement ball mill transmission: Central drive ball mill refers to the arrangement of the driving mechanism for the mill. In a central drive configuration, the motor and gearbox are positioned at the center of the mill, usually between the grinding chamber and the mill shell. This design is in contrast to an edge or end drive configuration where the motor and gearbox are situated at one of the ends of the mill. Central drive transmission systems typically involve a motor that powers a gearbox, which then transfers the rotational energy to the mill's main shaft. The central drive design can provide advantages in terms of power distribution and efficiency compared to other drive arrangements. It can also offer better control over the mill's operation.
PLC control system: PLC control system: A PLC is a digital computer-based system that is designed to control various industrial processes automatically. In the context of a ball mill, a PLC is used to monitor and control parameters such as temperature, rotation speed, air flow, fuel flow, and other critical variables that affect the performance of the ball mill and the quality of the products being processed.
Cutting-edge design: As one of the leading ball mill manufacturers, Tongli cement ball mills are advanced in design, integrating the cutting-edge technology, adapt to different product qualities.
Advanced manufacturing Equipment: Tongli has over 100 set of large-scale mechanical processing equipment, especially a 5.3x18-meter fully numerically controlled horizontal lathe to ensure the processing accuracy and concentricity of the ball mill.
Heat treatment: Tongli heavy machinery is equipped with a large annealing furnace of 6.5x6.5x20m and a large sandblasting room, which can conduct overall heat treatment and sandblasting on the ball mill to ensure the service life and appearance of the ball mill.
Process Control: Tongli has its own metal casting foundry, starting from the raw material to the finished product, Quality in every detail, from start to finish.
Multifunctional design: Tongli Ball mill is able to integrate drying and grinding function in one device.
Lubrication system: Tongli ball mill is equipped with force lubrication system, there is an oil station equipped for the transmission part, another oil station for the gearbox to ensure smooth operation and prolong service life of the ball mill.
Cooling system: The main bearing bush is equipped with a water cooling system, and a cooler is also installed in the lubrication system to forcibly cool the lubricating oil.
Transmission connection: Tongli’s ball mill is equipped with a transmission connection, which is welded on the cylinder and machined together with the ball mill shell to avoid assembly errors and ensure the concentricity of the ball mill.
Note: * Mill diameter refers to the inner diameter, while the mill length refers to the effective grinding length.

What is the difference between central drive ball mill and edge drive ball mill?
Central Drive Ball Mill and Edge Drive Ball Mill are two common types of grinding mills used in various industrial applications.
Central Drive Ball Mill: In this configuration, the motor is positioned in the center of the mill, and the shaft is driven directly through the central axis. The motor's power is transmitted to the mill via a gear unit, resulting in a balanced and efficient power distribution.
Edge Drive Ball Mill: In contrast, the edge drive mill utilizes a gearbox located on the periphery of the mill. The motor's power is transmitted to the mill through the gears, which are positioned around the shell. This design offers certain advantages in terms of installation and maintenance.
