ABSTRACT:
A process and apparatus for the regulation of continuously operating shot-blasting machines for achieving an approximately uniform shot-blasting effect on the workpieces independently of time variations in throughput of the workpieces. Throughput speed of the workpieces in the radiation chamber or the supply of shot-blasting medium to one or more centrifugal impellers is regulated in dependence on the quantity of workpieces to be blasted per time unit. The apparatus includes measuring apparatus (9, 9') for the measurement of the fed-in-workpieces (5), disposed in the radiation chamber (1) or in the feed-in arrangement (2), which measuring arrangement is connected by way of a measuring transducer (10) with a regulating circuit (11) for the change of the throughput speed of the workpieces (5) and/or with a regulating circuit (12) for the change of the throughput radiation means at the flywheel (4). The regulation is suitable for shot-blasting machines for drummable workpieces and guarantees lower machine wear and consumption of blasting medium.
