Product Details

Industrial Ball Mill for Mining & Cement

OreSolution's Ball Mill is the core equipment for material regrinding. It utilizes a rotating cylinder and grinding media (steel balls) to crush and grind materials.

Capable of both Dry and Wet Grinding, our mills are widely used in Mining (Gold, Copper, Iron), Cement, Chemicals, and Building Materials. We offer optimized cylinder structures and high-performance liners to ensure stable operation and uniform product fineness.

Working Principle: Impact & Attrition

The grinding process typically involves two distinct stages inside the cylinder:

Feeding & Impact

Crushed ore (≤25mm) from the Jaw Crusher enters the First Chamber. Large steel balls drop to crush coarse rocks via impact force.

Fine Grinding

Material moves to the Second Chamber. Smaller steel balls roll against the liner, creating attrition force to grind material into fine powder.

Discharging

Ground slurry flows into the Hydrocyclone or Spiral Classifier for size classification.

Industrial Ball Mill Structure and Liner Details

Technical Choice: Grid vs. Overflow Type

Feature	Grid Type (Grate)	Overflow Type
Discharge Structure	Has a Grate Plate (Low level).	Hollow Shaft (High level).
Application	Coarse Grinding (Primary stage).	Fine Grinding (Regrinding).
Capacity	~15% Higher.	Lower, but better for fine separation.

Core Advantages

Frequently Asked Questions (FAQ)

Q: How do I choose between Dry and Wet Ball Mill?

A: Wet Ball Mill is used for most mineral processing (Gold, Copper) as it allows for higher capacity and no dust. Dry Ball Mill is used when the material must remain dry (e.g., Cement, some chemical powders) or water is scarce.

Q: What is the service life of the liners?

A: It depends on the ore hardness. Generally, High Manganese Steel liners last 6-10 months. Rubber liners can last 1.5-2 times longer in fine grinding stages.

Q: How to select the steel ball size?

A: We recommend a mixed ball loading ratio (e.g., 100mm, 80mm, 60mm). Our engineers will calculate the precise Ball Loading Ratio based on your material analysis.
