Ball Mill Working Principle
A ball mill consists of a horizontal rotating cylinder lined with steel plates and filled with grinding media (steel balls or rods). As the cylinder rotates, the grinding media are lifted by centrifugal force and then cascade down, crushing the material through impact and friction. The crushed material gradually moves from the feed end to the discharge end through the mill’s chambers, with finer grinding achieved in subsequent compartments.
In single-compartment mills, the entire grinding process occurs uniformly, while multi-compartment mills use partition plates to separate coarse and fine grinding stages. The final ground powder is discharged through the outlet hollow shaft, with particle size controlled by adjusting rotation speed, grinding media size, and material retention time.

What is a Ball Mill?
The ball mill is a crucial equipment for material grinding after the crushing process. This type of grinding machine operates by loading a certain quantity of steel balls as grinding media inside its rotating cylinder.
Widely applied in cement production, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous mineral processing, as well as glass and ceramic manufacturing industries, it performs dry or wet grinding for various ores and other grindable materials.
The ball mill is suitable for pulverizing diverse ores and materials, extensively used in mineral processing, construction materials, and chemical industries. It can be categorized into two grinding methods: dry-type and wet-type. Based on different discharge methods, it can also be classified into two types: grate discharge and overflow discharge.
Cement Ball Mill
The cement ball mill is a horizontal cylindrical rotating device with external gear transmission. When the cylinder rotates, centrifugal force lifts the steel balls to a certain height before they fall to impact and grind the materials.
Specifically designed for cement raw material grinding, this industrial grinding equipment operates in two distinct modes:
- Dry-process grinding – For moisture-sensitive materials with air circulation
- Wet-process grinding – Utilizing water as transport medium for slurry formation
Key technical features:
- Heavy-duty girth gear drive system
- Standard capacity range: 5-150 t/h
- Final product fineness: 3000-3800 cm²/g (Blaine)
- Liner options: Wave, step, or corrugated types
Ball Mill Steel Ball
In a ball mill, the primary role of the steel balls is to impact and crush the materials, while also providing a certain grinding effect. Therefore, the purpose of ball grading is to meet both of these requirements. The effectiveness of the crushing directly affects grinding efficiency and ultimately impacts the mill’s production capacity. Whether the crushing requirements can be met depends on the rationality of the ball grading, which mainly includes the size of the steel balls, the number of ball diameter grades, and the proportion of balls of various specifications.
When determining these parameters, factors such as the size of the ball mill, its internal structure, and the required product fineness must be considered, along with the characteristics of the feed material (grindability, particle size, etc.).
Structural Features
-
Main Bearing: Utilizes large-diameter self-aligning double-row roller bearings instead of traditional sliding bearings, reducing friction and energy consumption while enabling easier mill startup.

A ball mill rotates a cylindrical shell with grinding media (steel balls), where materials are crushed by impact and attrition. The centrifugal force lifts balls, which then cascade down to pulverize materials to 45-300μm fineness.
Dry mills suit heat-sensitive materials (e.g., cement) with 10-15% lower energy use, while wet mills (e.g., mineral processing) achieve finer particles but require water and wear-resistant liners.
-
Optimize ball size ratio (e.g., 40% Φ100mm + 60% Φ60mm)
-
Adjust material feed rate to 75-85% of max capacity
-

Ball Mill Selection Guide
1. Ensure Production Capacity
Select a mill that achieves the target grinding fineness while meeting specified production output.
2. Overdesign Capacity Margin
Factor in ore hardness and fineness variations (e.g., deeper ore deposits tend to be harder/finer). Choose a mill capable of adapting to such changes while ensuring smooth initial operation.
3. Conduct Grinding Tests
For large-scale concentrators without existing data, mandatory grinding tests should provide baseline metrics for mill selection and scale-up calculations.
4. Consider Equipment Scale-up
Modern design favors larger equipment for:
• Reduced total weight/floor space
• Fewer operating systems/personnel
• Lower capital/operating costs
Note: Larger mills demand higher operational expertise as minor downtime significantly impacts output.
5. Prioritize Operational Reliability
Opt for high-availability models within each equipment class. While rod/autogenous mills may have lower uptime, they remain situationally viable.
6. Analyze Ore Properties
Evaluate mineral hardness and grade to select energy-efficient mills (e.g., models with roller bearings can reduce power use by 20-30%).
7. Target Particle Size Requirements
Match compartment diaphragm apertures and segmentation to required product fineness (typically 45-300μm adjustable).
8. Size Appropriately
Select drum diameter/length based on throughput needs (standard range: 1-150 t/h).
9. Choose Next-Gen Upgraded Models
Source from manufacturers specializing in your mineral type (e.g., lithium ore vs. cement clinker).
10. Verify Critical Components
Inspect:
• Gear module specifications (pinion & girth gears)
• Motor/reducer OEM qualifications
• Liner material grades (e.g., high-chrome steel)
• Drum shell thickness (typically 15-50mm)
Pro Tip: For >Φ3m mills, request FEA (Finite Element Analysis) reports on stress distribution.
Ball mills are industrial grinding machines used to:
-
Reduce particle size (typically to 45-300μm)
-
Blend materials (e.g., cement raw meal)
-
Prepare powders for mineral processing, ceramics, or pharmaceuticals
Key applications: Cement production, ore beneficiation, lithium battery material preparation
