Abstract:
The corridor for transporting abrasive in an impact chamber is laterally limited by longitudinal sections resting on a foundation slab. The corridor has a traction system for moving an axle set along a transport track, the traction system being provided with a substantially horizontal loop including loop return wheels and a loop connector having two bands moving in opposite directions. Each band of the loop connector is placed in an individually assigned guiding slot, arranged on top of the longitudinal section. There is a method for moving an axle set in an impact chamber having a corridor for transporting abrasive, wherein each band of the loop connector is carried in the immediate vicinity of the side edge of the corridor for transporting abrasive, on top of the longitudinal section.
