Overflow Ball Mill

Overflow ball mill adopts air clutch or liquid soft start to realize segmented start of the main motor and cylinder of the ball mill, reduce the installed power, and reduce the starting current from 6.5 times of direct start to 2.5 times. The overflow ball mill uses the rotation of the cylinder to drive the steel balls and ore to collide and rub in the cylinder, so as to achieve the purpose of crushing the ore. Compared with other types of ball mills, the overflow ball mill is equipped with an overflow device at the discharge end, so that the fine-grained product stays in the cylinder for a longer time, thereby achieving a finer grinding effect. The discharge particle size can reach 0.074-0.4mm, which is often used in processes that require fine-grained products. Experimental data shows that the overflow ball mill can grind the ore to a finer particle size within the same grinding time, which is suitable for fine grinding operations.

Advantages Of Overflow Ball Mill

High wear resistance

The barrel the overflow ball mill is welded by using steel plates with a thickness of 15-36mm. The flanges made of cast steel are welded on both ends of the barrel, and the end cover and the flange are connected together with a bolt. Its precision machining and coordination greatly improve the wear resistance of the components.

Automation control

Overflow type ball mill can use different ball mill liner types according to production needs and set the fineness of the grinding material. The overflow type ball mill can control the grinding time by itself and fully realize the automatic control.

Advanced component performance

The overflow discharge ball mill has a short stopping time during the working process, and the machine vibration is small during operation, so the equipment has a long working life. The overflow discharge ball mill has low labor intensity, which can save more manpower for customers.

Type of Overflow Ball Mill

Overflow ball mill equipment– short tube ball mill

The cylinder length L is less than twice the cylinder diameter D. The ball mill with L≤2D is a short cylinder ball mill, mostly with a single chamber structure, mainly used for rough grinding or primary grinding in mineral processing plants. Its operating efficiency is high, 2-3 ball mills can be used in series simultaneously, and its application range is wide.

Overflow ball mill equipment – medium and long barrel ball mill

When the cylinder length is L=3D, it is a medium and long ball mill. Generally, 1 or 2 bins can be used for coarse or fine-grain operations.

Overflow ball mill equipment – long cylinder ball mill

When the cylinder length is L≥4D, it is a long ball mill, generally divided into 2-4 bins and mainly used for fine-grained material grinding.

Applications of Overflow Ball Mill

Ore grinding

Overflow ball mills are often used in the wet grinding process of ore in mines.For example, in a gold mine, the ore is ground by an overflow ball mill to refine it into a suitable particle size for subsequent extraction and smelting processes.

Mineral processing

Overflow ball mills also have important applications in mineral processing.For example, in the silicate industry, ball mills are used to grind quartz sand or other ores into powder for use in ceramics, glass and other industries.

Metallurgical industry

Overflow ball mills play a key role in the metallurgical industry.For example, in the metallurgical process, overflow ball mills are often used to grind ore or metallurgical slag to obtain the required particle fineness and facilitate subsequent mineral separation and extraction processes.

Material preparation

The application of ball mills is not limited to ore and mineral processing, but can also be used to prepare various materials.For example, in the ceramic industry, overflow ball mills can be used to grind ceramic raw materials to prepare ceramic particles or carcasses.

Chemical industry

The application of overflow ball mills in the chemical industry is also more common.For example, in the pigment grinding process used in pigments, dyes and other fields, a ball mill can be used to refine the pigment particles and evenly disperse them in a solvent.

Working Principle of Overflow Ball Mill

Rolling bearings support the barrel of the overflow ball mill, which rotates slowly through the transmission mechanism. The material is fed from the feeding end of the barrel, and the material is crushed in the barrel due to the impact and self-grinding of steel balls and ore itself. Due to the continuous feeding of materials, the pressure promotes the material in the barrel to move from the feeding end to the discharging end. The ore slurry is higher than the lower edge of the hollow shaft at the ore discharging end and overflows by itself. The hollow shaft has anti-helical blades, which can return the overflowing steel balls and coarse ore blocks to the mill.

The main bearing is a key part of the overflow ball mill equipment, and full attention must be paid to its lubrication. Generally, thin oil is used for centralized circulation lubrication. The oil flows through the pump and is pressed into the main bearing and transmission bearing in four ways, then discharged to the drain at the bottom of the bearing oil pipe, and then back to the tank. For medium and small ball mills, there are methods such as automatic oil ring lubrication, oil cup drip lubrication, or solid lubricant. Some concentrators are equipped with an automatic oil cut-off alarm device to ensure the reliability of lubrication.

The overflow-type ball mill is supported on the main bearing through the hollow shafts at both ends. Among the two hollow shafts, one of the two hollow shafts can be axially expanded and contracted on the main bearing, and the other is fixed. Since the gear transmission of the ball mill will generate an axial force, a hollow journal is designed with two shoulders, and the distance between the shoulders is exactly equal to the length of the bearing bush, thereby preventing axial movement. The other hollow journal has no shoulder, and its length is 5-25mm longer than the bearing bush. When the cylinder is heated and stretched or deflected due to load, it can freely expand and contract within a certain range. Generally, the journal close to the transmission ring gear is selected as a fixed hollow journal. The hollow journal is equipped with a tapered bush and a bearing bush, and the cooperation between the hollow journal and the inner sleeve must be tight and sealed. To make the slurry surface in the ball mill have a certain inclination, the inner diameter of the hollow journal at the discharge end is slightly larger than the inner diameter of the hollow journal at the feed end. The inner surface of the hollow journal can be smooth or with spiral blades. The forward spiral blades in the hollow journal at the feed end are used to transport materials; the reverse spiral blades in the hollow journal at the discharge end can make coarse particles Material returns and prevents balls from running out. The transmission gear ring is fixed on the barrel at the ore discharge end, and meshes with the pinion, and the motor drives the barrel through the pinion gear and the gear ring.

Overflow Ball Mill Design

The structural integrity of an overflow ball mill begins with the robust construction of its shell and frame.
Utilizing durable materials such as steel, the shell is designed to withstand mechanical stresses.
End covers enclose the mill, offering structural support and facilitating maintenance access.
Careful consideration is given to trunnion design, ensuring smooth rotation with proper bearings and lubrication systems.

The efficiency of the ball mill depends on the design of its rotating components.
The mill drum houses grinding media and materials, with internal liners tailored for optimal grinding.
The drive system, consisting of a motor, gearbox, and couplings, provides the necessary power for rotation.
Special attention is paid to the discharge system, preventing overgrinding through controlled overflow outlets and incorporating mechanisms for particle size control.

Modern horizontal ball mills feature advanced control and monitoring systems.
These systems incorporate instrumentation to measure key parameters and control panels for operational adjustments.
Safety is ensured through protective guards, emergency shutdown mechanisms, and accessibility considerations for routine maintenance.
Effective sealing and dust control measures are implemented to maintain a clean and safe operating environment.

In essence, the meticulous structural design of a horizontal ball mill encompasses a sturdy foundation, efficient rotating components, and well-integrated control and safety features.
