Maintenance of your crushing and grinding equipment

Maintenance of aggregate production equipment

In quarry facilities where the materials to be treated are abrasive, maintenance takes a significant part of the operating costs. It represents between 15 and 40% of the variable costs. It is therefore essential for a facility to reduce these maintenance costs in order to increase its productivity. In addition, poor maintenance of aggregate production equipment leads to a loss of product quality in terms of homogeneity and regularity. But also potential risks in terms of operator, environmental and financial safety.

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

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

Our maintenance solution is composed of four packages:

Our know-how in machine maintenance

Through a fast, high-quality service, our goal is to limit your machine downtime. Because a broken machine is a 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 equipment as soon as possible.

Also, for more complex interventions, our experienced 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 technicians can also carry out boring, reloading, etc.
