Dry Ball Mill

Dry Ball Mill is the core grinding equipment in mining, metallurgy, cement, and chemical industries. It is suitable for grinding high-hardness materials such as iron ore, copper ore, and quartz, as well as special material processing, such as slag and fly ash. It has a robust structure, large processing capacity, and easy maintenance. It is used as key equipment for grinding in mineral processing production lines and can be combined with classifiers and dust collectors for continuous and efficient operation.

When selecting the model, it is necessary to optimize the configuration according to the material hardness and grind ability (such as φ2400×4500 is suitable for iron ore, φ1830×3000 is suitable for limestone) and production requirements (such as closed-circuit grinding system and wear-resistant lining). In the future, it will develop in the direction of intelligence and energy efficiency, and further improve grinding precision and resource utilization.

Products Display

Coarse grinding materials (product fineness 0.1-3mm, such as iron ore, copper ore, etc.)

Material characteristics: large particle size after crushing, high grinding resistance, need for uniform particle distribution

Dry Ball Mill selection recommendations:

• Model selection: φ2700×4500 and above large models are preferred

• Liner material: high-chromium cast iron or composite wear-resistant steel

• Ball ratio adjustment: increase the proportion of large-diameter steel balls (φ80-100mm) to 40-50%
Fine grinding materials (product fineness 74-150μm, such as limestone, feldspar, etc.)

Material characteristics: small feed particle size, good grind ability, high requirement for particle uniformity

Optimization plan:

• Model selection: φ1830×3000-φ2400×4500 series can meet most needs

• Grinding medium configuration: use medium-diameter steel balls (φ40-60mm) with reasonable grading

• Efficiency improvement: adopt closed-circuit grinding with classifier, increasing production by 15-20%

Material Application

High-hardness grinding materials (Mohs hardness ≥6)

Typical materials: ▸ Iron ore (magnetite, high density) ▸ Copper ore (sulfide content, uneven hardness) ▸ Quartz (strong abrasiveness) ▸ Chromite (high specific gravity, brittle texture)

Application scenarios: Mineral processing grinding in metal mines, raw material grinding in refractory production, quartz sand processing in glass industry, ore beneficiation pretreatment

Medium-hardness grinding materials (Mohs hardness 3-5)

Typical materials: ▸ Limestone (easy to grind) ▸ Feldspar (alkaline components, stable grinding performance) ▸ Slag (glass phase structure, good grindability) ▸ Gypsum (hydrous sulfate, low abrasion)

Application scenarios: Raw material grinding in cement plants, powder production in building materials industry, additive processing in chemical engineering, desulfurization material preparation in power plants
