Vacuum extraction in underground mines
In a gold mine, large rocks and stones are taken out of the mine with conveyor belts. In a second work step the tunnels are being cleaned with powerful suction units based on KS-units. Fine dust and smaller stone particles which are being created by the used explosives contain the highest gold concentrations so that the investment in suction units is amortised within a short period of time.

Cleaning of conveying equipment in a gravel plant
Spilled material at conveying plants, dust which has settled at processing equipment and large amounts of material at blockages or after accidents are being removed with an S-3 and a mobile intercept hopper. The units are brought to the area which needs to be cleaned. Alternatively, the intercept hopper can be connected to a fixed pipeline system, so that also higher levels of the plant can be cleaned. The intercept hopper is transported with a fork lift truck. If the suction material is to be recycled, it can be discharge onto a conveyor belt or into a screening machine.
