As part of the upgrade, AUMUND is supplying a package of equipment, including belt bucket elevators to feed the 96 m heat exchanger and the raw meal silo at the plant. Two BWZ chain bucket elevators will be used to convey raw meal and filter dust, as well as silo feed, while a KZB pan conveyor with a 9 m vertical lift will be installed under the clinker cooler.
The German-based company will also supply seven LOUISE-type drag conveyors with show centre distanced of 13 m and conveying capacities between 7 and 50 tph. Two CENTREX machines (25 – 250 tph) will extract limestone and clay, as well as iron ore, from silos up to 7 m high.
The Martres-Tolosane project is part of a €300 million investment being made by LafargeHolcim in France. The upgrade will focus on environmental protection to make the plant fit for the future.
