Pneumatic sanding device, and corresponding method

Compressed air-driven sand-distributing device (10) comprises a sand container (14), a compressed air source (12), a sand intake chamber (36), and a nozzle (20). The nozzle has an air inlet, an ejection channel (26) and a sand intake opening (28). The sand intake chamber is directly or indirectly connected to the nozzle via the sand intake opening. A sand line (40) is arranged downstream of the nozzle in the flow direction. An air supply (42) opens into the sand line. The air supply and the nozzle are connected to the same compressed air source. Devices (18) are used to adjust the ratio of the quantity of compressed air fed from the compressed air source to the nozzle and to the air supply. An Independent claim is also included for a process for distributing sand.
