Product Overview

The cement ball mill is the core equipment in cement grinding systems, widely used for dry or wet grinding of cement clinker, limestone, slag, fly ash, and various ores. As a traditional and reliable grinding solution, the ball mill has been the backbone of cement production for over a century.

LIMING cement ball mills feature optimized compartment design, wear-resistant manganese steel liners, and precision-forged steel balls. The mill operates continuously with a rotating horizontal cylinder partially filled with grinding media (steel balls). As the cylinder rotates, the balls cascade and crush the material through impact and attrition, producing cement powder with controlled fineness.

Our ball mills are available in models ranging from φ1.2×4.5m to φ4.2×13.0m, suitable for both open-circuit and closed-circuit grinding operations paired with separators for enhanced classification efficiency.

Buying Guide: 6 Factors Affecting Ball Mill Price

Make an informed purchase decision by understanding what determines the cost

1. Cylinder Size

Larger diameter and length increase material and manufacturing cost. φ4.2m mills cost significantly more than φ2.2m mills due to steel consumption and machining complexity.

2. Motor Power

Higher-capacity motors (up to 1250kW) increase cost. Slip-ring motors with liquid resistance starters add 8-12% to the total equipment price.

3. Liner Material

Standard manganese steel is cost-effective; high-chrome or chromium-molybdenum alloy liners cost 2-3x more but offer 3-5x longer service life.

4. Auxiliary Equipment

Separator, dust collector, elevator, conveyor systems add 30-50% to the base mill cost for a complete grinding station.

5. Automation Level

PLC-based control systems, temperature/vibration monitoring, and automated lubrication add 15-25% but significantly reduce long-term operating costs.

6. Transportation & Installation

Shipping costs for heavy equipment (6.5-280 tonnes) and on-site installation can add 10-20% depending on distance and site conditions.

Working Principle

  1. Material Feeding: Cement clinker (or other material) and gypsum are proportionally fed into the mill through the feeding device at the inlet trunnion.
  2. Primary Grinding (Chamber 1): The material enters the first grinding chamber where larger steel balls (φ60-130mm) crush the coarse particles through impact force as the cylinder rotates.
  3. Material Transfer: Partially ground material passes through the intermediate diaphragm into the second chamber, which retains the grinding media while allowing fine material to pass.
  4. Fine Grinding (Chamber 2): Smaller steel balls (φ20-50mm) in the second chamber grind the material to the desired fineness through attrition and abrasion.
  5. Discharge: Ground cement powder exits through the discharge grate at the outlet trunnion. In closed-circuit systems, it is then transported to a separator for classification.
  6. Classification (Closed Circuit): Coarse particles are returned to the mill for regrinding, while the fine product meeting specifications is collected in bag filters and conveyed to cement silos.

Frequently Asked Questions

What is the capacity of the cement ball mill?
LIMING cement ball mills range from φ1.2×4.5m (0.65-2 t/h) to φ4.2×13.0m (160-615 t/h), covering all requirements from laboratory-scale to large industrial cement plants producing over 5,000 t/d of clinker.
How much does a cement ball mill cost?
The price varies significantly based on model, motor power, liner material, and included auxiliary equipment. A small φ1.5×5.7m mill costs considerably less than a large φ4.2×13.0m mill. Contact our sales team with your specific requirements (capacity, feed material, target fineness) for a detailed quotation.
What is the maintenance rate of a ball mill?
LIMING ball mills are engineered for low maintenance: bearing lubrication every 8 operating hours (automated systems available), monthly liner inspection, quarterly girth gear/pinion alignment checks, and annual complete overhaul. The long-life bearing design achieves 100,000+ hours service life with proper maintenance.
How much floor area does a ball mill require?
Footprint varies by model. A φ2.2×6.5m mill requires approximately 12m × 4m foundation, while a φ4.2×13m mill needs about 16m × 6m. We provide complete foundation drawings and base frame specifications for your site planning and civil works.
