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.
- High production
- Full mobility
- Full electric drive
- Available with Lokolink mobile conveying system
LT1620E is used in primary crushing stage. It is typically loaded with an excavator or wheel loader. Vibrating feeder transfers the oversize blocks to the impactor which reduces them to the desired size. Undersize material drops through the grizzly directly on to the main conveyor which discharges the primary product further in the crushing process. Optionally fine gradations can be directed to the side conveyor.
How it works
LT1620E is track mounted fully mobile jaw crusher plant. It can be moved flexibly in different locations at the site. The Lokotrack LT1620E power transmission is fully electric. Electric power transmission offers the possibility to use electric power either from the external grid, or generated by the on-board diesel generating set. The Lokotrack LT11620E can be equipped with a grizzly feeder, or alternatively with a pan feeder and vibrating grizzly. For scalping sticky feed materials, a wobbler grizzly is also available.
Lokotrack LT1620E can be used with fully mobile Lokolink mobile conveying system. It is also available with several other options such as rock breaker and high pressure water spraying system.
