Title: METHOD AND DEVICE FOR ASCERTAINING THE OPERATING STATE OF A BLASTING SYSTEM
Abstract:
The invention relates to a method for ascertaining the operating state of a blasting system for treating the surface of a workpiece (4) by means of a blasting agent (3), having the following steps: continuously measuring the fill state of blasting agent (3) in a main bunker (5) provided upstream of a blasting device (1); subsequently metering blasting agent (3) from a pre-bunker (9) provided upstream of the main bunker (5) into the main bunker (5) such that the fill state in the main bunker (5) is kept within a specified fill state range; measuring the weight subsequently metered from the pre-bunker (9) to the main bunker (5) and detecting the measured weight over time; measuring the current consumption of a blasting agent accelerating device (2) and measuring an actual blast duration; determining a blast duration time interval; ascertaining an average blasting agent use for a specified point in time from the total blasting agent (3) weight subsequently metered during the specified blasting duration time interval up to the specified point in time; repeating the step of ascertaining the average blasting agent use for subsequent additional specified points in time; and displaying the respective average blasting agent use over the respective specified points in time.
