What is a ball mill?

A ball mill, also known as a ball mill machine, is a grinder that reduces the size of materials by using a rotating cylinder filled with grinding media such as steel balls or ceramic balls.

Ball mills are primarily used for crushing and grinding materials. They can handle feed from a jaw crusher in the primary grinding stage or feed from other grinding equipment, like a rod mill or SAG mill, in the secondary grinding stage.

Ball mill applications

Ball mills are commonly used in industries such as mineral processing, cement production, chemicals, ceramics, and fertilizers to crush and grind various materials such as ore, limestone, quartz, coal, etc.

1. Mining and mineral processing

Ball mills are widely used in the grinding process of various metal ores, including gold ore, copper ore, iron ore, silver ore, zinc ore, tungsten ore, and lead ore. By reducing ore particle size, valuable minerals can be extracted more effectively.

Additionally, ball mills are used to grind materials like bentonite, kaolin, barite, and talc. In ore processing, ball mills typically work alongside crushers, flotation machines, magnetic separators, and gravity separators.

2. Cement grinding

Cement ball mills are mainly used to grind clinker and gypsum into fine powder for cement production. They can also be used to grind materials like slag, pozzolana, dolomite, and fly ash, which are added to cement to improve its strength and durability.

3. Fertilizer production

In fertilizer production, ball mills are used to grind raw materials like phosphate rock and limestone into fine powder, and to effectively mix materials like urea and ammonium nitrate, enhancing the quality of the fertilizer product.

Ball mills are also widely used for grinding coal, coke, construction materials, glass, silica sand, marble, and other materials.

4. Ceramics roduction

In the ceramics industry, ball mills are used to grind ceramic raw materials, such as feldspar, quartz, and clay. The finely ground materials can form a more uniform slurry, leading to ceramic products that are more consistent and durable.

In addition to grinding, ball mills are also used for mixing, stirring, and dispersing materials. They are popular in industries such as chemicals, pharmaceuticals, and food processing.

Ball mill types

Ball mills come in various types based on applications and process requirements. Below are the types classified by process conditions, structural form, grinding media, and length-to-diameter ratio of the drum.

1. By process conditions

Dry ball mill: Grind the material into mineral powder with the required fineness. Dry ball mills are suitable for hard materials like silica sand, quartz, marble, and cement clinker.

Wet ball mill: Grinds materials into a slurry with a specific concentration, typically 60%–70%. Wet ball mills are commonly used in mineral processing and usually have a single-chamber structure.

Difference: The key difference between dry ball milling and wet ball milling is whether water is added during the grinding process. Adding water means wet type.

2. By structural form

Overflow type ball mill: Produces finer grinding results and is suitable for the second stage in a two-stage grinding process. The feed size is generally less than 0.2 mm. Its output is about 15% lower than that of a grid type ball mill of the same size, and it also uses less grinding media.

Grid type ball mill: Suitable for situations where the product particle size is 0.2 mm–0.3 mm and needs to be uniform. This type of mill quickly discharges qualified products, reduces over-grinding, and increases grinding efficiency. It is often used in the first grinding stage.

3. By grinding media

Ball mill: Uses cast grinding steel balls and forged grinding steel balls as the grinding media.

Rod mill: Uses grinding rods and grinding cylpebs as the grinding media.

Ceramic ball mill: Uses ceramic balls as the grinding media.

4. By length-to-diameter ratio of the drum

Ball mill: A typical ball mill has a drum length that is equal to or 1.5 times the drum diameter.

Tube mill: A mill with a drum length-to-diameter ratio greater than 1.5 is referred to as a tube mill.

Ball mill working principle

Step 1 Loading: First, the material to be ground and grinding media (such as steel balls or ceramic balls) are loaded into the ball mill cylinder. Typically, the grinding media fills 30% to 45% of the cylinder's volume.

Step 2 Rotational motion: When the ball mill starts, the motor drives the cylinder to rotate. As the cylinder turns, the grinding media are lifted to a certain height by centrifugal force.

Step 3 Impact: Once the grinding media reach a certain height, gravity causes them to fall, generating a strong impact force on the material. This force breaks or crushes the material.

Step 4 Abrasion: In addition to impact, friction between the grinding media and between the media and the cylinder walls further refines the material through abrasion.

Step 5 Discharge: After repeated impact and abrasion, the material is ground to the desired fineness and is discharged through the outlet.
