Innovative Solutions for Industry Advancement

Harcliff Mining Services is a pioneering force in the engineering and manufacturing sector, offering cutting-edge solutions tailored to meet the evolving needs of modern industries. With over two decades of experience, we have continuously pushed the boundaries of innovation, setting new standards of excellence in everything we do.

Our Expertise


The design process is the first crucial step in any engineering project. We not only have a highly experienced design team, but also the technical resources to develop and produce world-class products. Harcliff utilises the latest techniques and technologies, including mechanical 3D computer modelling, KISSsoft, Inventor modelling, Ansys software, laser scanners, 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 cylindrical gear grinding machinery which enables accuracies of AGMA Q12 and higher. A critical gain from the use of these advanced technologies is that manufacturing cycle times are also significantly shorter.


We refurbish a wide range of equipment, including grinding mills, gearing and gearboxes, kiln and dryer components, and rotary scrubbers. Every refurbishment is treated as a turnkey project, which 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 your site, installation, commissioning and condition monitoring. This service is available internationally via our global partners.
