Harcliff boasts an exceptionally high ratio of technically skilled and qualified personnel – a legacy from our founder, who was a talented artisan with an instinctive feel for machinery. This passion for mechanical excellence extends to our engineering and artisan team of which every member is a qualified artisan, fully able to assess and respond to your specific needs and expectations.

The design process is the first crucial step in any engineering project. We not only have a highly experienced design team but the technical resources to develop and produce world-class products. Harcliff utilises the latest techniques and technologies, including mechanical 3D computer modelling, KISSsoft and Inventor modelling, to develop designs for our mill and gearing products.


We take a disciplined and systematic approach to manufacturing activities, all of which are undertaken in line with the highest international quality standards. Outstanding workmanship is aided through our investment in state-of-the art technology, including a Höfler 2000 cylindrical gear grinding machine which enables accuracies of AGMA Q12 and higher. A critical gain from the use of these advanced technologies is that manufacturing cycle times are significantly shorter.


We refurbish a wide range of equipment, including mills, gearing and gearboxes, kiln and dryer components, crushers and rotary scrubbers. Every refurbishment is treated as a turnkey project and includes removal from site, renovation, transportation, installation and commissioning. We also convert previously-owned mills to different specifications as a cost-effective option where the purchase of new milling machinery may be limited by budgetary or time constraints.


The installation process is a vital component of Harcliff Mining Services’ holistic service offering. The process begins with the transportation of your equipment to site, installation, commissioning and condition monitoring. This service is available internationally via our global partners.
