For the extraction of raw materials, an existing quarry pond is to be completely be completely regravelled. The aim is to achieve extraction with as little loss as possible 0 - 125 mm while complying with technical and operational operational requirements. The existing land conveyor system will be used to ensure an efficient material flow.

Efficient Regravelling despite large lake width (up to 275 m)

Reliable material material conveying in the grain size range 0 - 125 mm

Stable operation over a longer period of time with even raw material extraction

Adaptable mining method, even with fluctuating deposit geometry

Integration into existing infrastructure, especially conveyor system

Regravelling is carried out using the KS 1000 R scraper system, which is installed on the existing installed on the existing land conveyor system. A floating return pulleys, anchored on the opposite bank opposite bank, enables a scraper path of around 250 metres. This ensures constant solids output of around 150 tonnes per hour.

A vibrating grid with a gap width of approx. 125 mm ensures the targeted separation separation of oversize particles. Material larger than 125 mm is removed via a discharged onto the subgrade via a separate chute.

Mining takes place in side block cutting:
After an initial cut at the beginning of the at the start of the drift, work is carried out continuously along the towards the slope. Depending on the post-breakage behaviour, the the back width is adjusted. In normal operation, rectangular segments are in parallel. If required, it is possible to temporarily switch to swivel mining swivel mining can be temporarily switched to, whereby the feed onto the serves as a pivot point.

The extracted material is continuously conveyed via an automatically controlled pendulum feeder and dewatering screen onto an intermediate belt and from there onto the from there to the existing conveyor system.
