ABSTRACT:
The present invention relates to a device for separating blasting dust from blasting agent, whereby separation occurs in a separating space (16) from which the blasting dust (15) is sucked into a dust collecting device (19) while the blasting agent (13) is fed to a recirculating device (12) for recycling thereof, and whereby the blasting dust (15) is sucked into the dust collecting device (19) by generating a negative pressure therein by means of a negative pressure-generating device. In order to eliminate the need for bulky fan devices for generating negative pressures in the dust collecting device, the negative pressure-generating device includes an air guide means (32) which is connected to a compressor (9) and feeds air from said compressor in a direction from a blasting dust inlet (30) towards a collecting container (21) for blasting dust (15).
