Description

Overview
  • FLSmidth Ball mills deliver high-throughput ore grinding with strong energy efficiency to maximise mineral recovery and reduce total cost of ownership. Designed for continuous operation with high reliability, they incorporate advanced process control, digital tools and engineered mill liners to increase uptime and productivity.


Key benefits
  • Proven technology supported by lifecycle services including installation, commissioning, process optimisation and maintenance.
  • Flexible size range (adapts to processing needs) and configurable for open or closed circuits with cyclones for finer product sizing.
  • Digital tools (LoadIQ smart sensor, ECS/ProcessExpert Advanced Process Control) to automate mill condition response, improve ore reduction and energy efficiency.
  • Options for customised discharge arrangements and drive trains to match process and plant layout.


Applications
  • Primary grinding (after pre-crushing), secondary grinding (following a SAG mill) and regrind applications.
  • Wet grinding and dry grinding (can be combined with drying chambers and hot gas generators to achieve required moisture content for downstream processing).


Design & configurations
  • Size range: diameters from 1.6 m up to 8.5 m.
  • Power: up to 22,000 kW available for high-capacity installations.
  • Support method: trunnion-supported or shell-supported designs.
  • Drive options: high-speed motors with reducers, low-speed motors coupled to pinions, or Gearless Mill Drives (GMDs); geared solutions can be single or dual pinion (references up to ~10,000 kW per pinion).
  • Discharge arrangements: plain extended chute, trunnion magnet or trommel screen (customisable to process/layout needs).
  • Main bearings: hydrostatic or hydrodynamic options; sleeve or multi-pad (self-aligning) bearings.


Add-ons & optimisation
  • Mill wear parts and advanced liners to increase service life and grinding efficiency.
  • LoadIQ sensor technology to optimise mill loading and improve control.
  • Advanced Process Control (ECS/ProcessExpert) to automate adjustments for improved reduction and energy efficiency.
  • Smart mill liner packages, liner profiling and 3D scanning services for accurate wear measurement and wear-life optimisation.


Maintenance & lifecycle services
  • Comprehensive lifecycle services: installation, commissioning, process optimisation, regular maintenance, shutdown support and tailored mill liner services to increase uptime and performance.
  • Advanced liner profiling, scanning and wear prediction technologies to support planning and reduce total cost of ownership.


Sustainability features
  • Lightweight composite mill liners reduce installation time and maintenance exposure.
  • Options for low-carbon mill liner manufacturing and component reuse/recycling to support circularity and lower greenhouse gas footprint.
