A dosage device for feeding grained, pourable materials, particularly abrasive blasting materials. Feeding is accomplished by use of a dosage auger that employs a screw mechanism that either decreases or increases relative to the distance between the incline of the spiral wings. The device also includes an adjustable drive, a flow measuring device to monitor and control flow rates and a mixing chamber to assure full mixing of abrasive material in a compressed air stream.
