Maintenance of your crushing and grinding equipment in the aggregates industry

Maintenance of aggregate production equipment

In quarry facilities where the materials to be treated are abrasive, machine maintenance takes a significant part of the operating costs of your fixed plants solutions for quarrying. It represents between 15 and 40% of the variable costs. It is therefore essential for an aggregates production equipment facility to reduce these machine maintenance costs to increase its productivity. In addition, poor maintenance of aggregate production equipment leads to a loss of mineral product quality in terms of homogeneity and regularity. But it leads also to potential risks in terms of operator, environmental and financial safety. It also can end up in breakdowns of your aggregates production equipment because of damaged parts or components. Our mining experts and technicians will be able to conduct repairs or replace the mining and quarrying parts and components on your machinery. Replacements that are also possible with used mining and aggregates parts reconditioned for your machinery.

To ensure the proper functioning of your aggregates production facilities, we offer a machine maintenance service to optimize your maintenance costs and to gain productivity thanks to reduced downtime of your mining equipment. 

Our technicians work on all your grinding and crushing equipment: cones, jaws, strikers, shafts, bearings, eccentrics, rotor, vertical axis…
