MILL DESIGN, MANUFACTURE & INSTALLATION

From design and manufacture to installation, commissioning and a comprehensive aftermarket service, Harcliff mills are designed with cost-effectiveness in mind. Fast-tracked deliveries are undertaken when required.

Every mill design is accompanied by:

  • Finite element modelling to determine potential high-stress areas
  • Ore-specific ball charge trajectory simulations
  • Mechanical 3D computer modelling
  • All drive trains are designed and constructed to meet American Gear Manufacturing Association (AGMA) standards.
  • Material grades undergo a rigorous selection process to optimise the strength and durability of your mill.

REFURBISHMENT & RELOCATION OF PRE-OWNED MILLS

When you need a new mill, budgetary or time constraints may be a limiting factor. We can refurbish your mill or convert a previously-owned unit to meet your specific needs. For example, a ball mill may be converted into a SAG mill or a rod mill into a ball mill.

Refurbishment is treated as a turnkey project – starting with the removal of your mill and redesign work (when required) and moving on to manufacturing replacement equipment, meticulously renovating mill components, transportation, installation, commissioning and maintenance.
