1. PAINPOINT DRIVEN OPENING

Are you managing grinding circuit inefficiencies that directly impact your plant’s bottom line? Common operational challenges with industrial ball mills include excessive energy consumption per ton of processed material, unplanned downtime due to mechanical failures, and inconsistent grind size affecting downstream recovery rates. These issues translate to quantifiable costs: escalated power bills, lost production hours, and suboptimal mineral liberation. Are you seeking a reliable ball mill solution that prioritizes operational continuity, reduces specific energy consumption, and delivers a consistently uniform product for flotation or leaching? The following white label ball mill datasheet details an engineered approach to these persistent challenges.

2. PRODUCT OVERVIEW

This document details a White Label Ball Mill engineered for continuous, heavyduty grinding in mineral processing and industrial milling operations. The equipment is a robust horizontal cylindrical shell rotating on its axis, driven by girth gear and pinion or direct drive systems.

Operational Workflow:
1. Feed Introduction: Crushed ore (typically <25mm) is conveyed into the mill via a feed chute.
2. Grinding Action: The rotation lifts steel grinding media (balls), which cascade and tumble, impacting and abrading the ore particles.
3. Particle Size Reduction: Continuous comminution occurs through impact and attrition until particles are reduced to the target size.
4. Discharge: Ground slurry or powder exits via discharge grates, ensuring only sufficiently fine material passes through.

Application Scope: Ideal for wet or dry grinding of ores (copper, gold, iron), industrial minerals (limestone, quartz), and raw materials in cement production.

Limitations: Not suitable for primary crushing of large feed sizes or for processing highly abrasive materials without specific liner and media alloy considerations. Optimal efficiency is achieved within defined feed size and moisture content parameters.

6. APPLICATION SCENARIOS

Copper Concentrator – Throughput Increase Challenge

Challenge: An existing concentrator needed higher throughput but was limited by an older ball mill’s capacity at the desired grind size of P80=150µm.
Solution: Implementation of a new white label ball mill designed with a larger effective grinding volume and optimized liner profile for the specific ore hardness.
Results: Mill throughput increased by 18%. Specific energy consumption decreased by 7%, meeting the expanded plant feed rate target without compromising recovery.

Industrial Minerals Producer – Maintenance Cost Reduction

Challenge: Excessive annual downtime (>400 hours) due to frequent liner changes in multiple ball mills processing abrasive quartzite.
Solution: Retrofit installation of specialized highchrome alloy liners with boltless fixation system into existing white label ball mill shells.
