High capacity with mobile impactor
The Austrian construction company Bernegger was facing a problem years ago, when the limestone quarry next to their aggregate and cement production plant became depleted. The planned new quarry site was located three kilometers (two miles) away in the mountains, and tight environmental restrictions would be applied to control all operations.
The solution was to place a Lokotrack® LT1620E™ and a Lokolink belt conveying system in the new quarry face. Primary crushed limestone is conveyed into a 160 m (525 feet) high vertical shaft, and then conveyed 3.5 km (2.2 miles) by a belt conveyor placed inside a tunnel. The complete primary crushing and belt conveying system is electric driven, and the 15% declined tunnel conveyor is even used for generating electric power. This solution makes it possible to minimize all environmental impacts and the total production cost. The LT1620E has an average production of 1 000 mtph (1 100 stph) of 0–100 mm (0–3 7⁄8”) primary crushed limestone.
