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 plant 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 in order 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. 

To ensure the proper functioning of your aggregates production facilities, we offer a machine maintenance service to optimize your maintenance costs and anticipate the risks of aggregates production machine downtime. 

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

Our machine maintenance solution is composed of four packages:

Our know-how in machine maintenance for the aggregates industry

Through a fast, high-quality machine maintenance and repair service, our goal is to limit your aggregates production machine downtime. Because a broken machine is an unwanted production stop! 

Our response trucks allow us to intervene in complete autonomy on-site to carry out the maintenance of your quarry and sandpit equipment, and thus restore your aggregates production equipment as soon as possible. 

Also, for more complex interventions, our experienced machine maintenance and repair technicians dismantle the defective parts and return them to our workshop in Sorgues (84) for repair and overhaul, and then reassemble them on-site. 

In our workshop, our machine maintenance experts can also carry out boring, reloading, etc.
