  • a bunker for receiving blasting agent is provided with a weight measuring device.
  • the treatment agent is manually replenished in the bunker. In this way, an undesired forced interruption of jet operation due to an insufficient quantity of treatment agent can be avoided.
  • the DE 31 31 002 A1 describes an automatic pressure blasting system with precise and reproducible dosing of the blasting agent.
  • the pressure blasting system includes two main bunkers, each with a minimum and a maximum fill level switch, which, when a minimum fill level is detected, causes automatic refilling from a refill bunker until the maximum fill level is reached.
  • the DE 10 2015 000 632 A1 discloses a method for operating a particle beam system and a particle beam system.
  • the throughput of the blasting agent is measured during operation using an inductive measuring device. From the WO 2014/040125 A1 an inductive level measurement in blasting systems is known.
  • the EP 0 456 502 A1 discloses a device for detecting a radiance or intensity in a blasting process. The measurement is based on the detection of sound waves.
  • the DE 103 32 713 B3 relates to a beam intensity measuring device for surface treatment facilities.
  • the beam intensity measuring device comprises an impulse sensor for measuring the impulse generated by the beam of blasting agent.
  • blasting media with a specific predetermined grain size distribution are used in state-of-the-art blasting systems.
  • the blasting agent is thrown against a surface of the workpiece to be treated by means of a blasting agent acceleration device, for example a turbine wheel or the like.
  • the blasting abrasive is then returned to the main bunker and is thus ready for further surface treatment.
  • the proportion of fines in the grain size distribution of the blasting agent increases over time.
  • the fines are removed from the blasting medium by means of air classification.
  • new blasting media is added to the blasting media.
  • the new blasting agent is usually fed from a pre-bunker to the main bunker when the fill level in a main bunker falls below a minimum level.
  • the pre-bunker is then usually refilled manually.
  • blasting agent In the case of blasting systems according to the prior art, the consumption of blasting agent is usually determined or estimated empirically, depending on the surface to be treated. The efficiency of a blasting system is not determined according to the state of the art.

  • the term “actual blasting duration” is understood to mean a period of time during which the blasting agent hits the surface to be treated with a predetermined minimum impulse.
  • the minimum impulse can be recorded indirectly through the power consumption of the blasting agent acceleration device. i.e. the blasting duration corresponds to the duration during which the blasting agent acceleration device works properly and is properly exposed to blasting agent.
  • idling operation must be distinguished, for example, during which the blasting agent acceleration device is driven but not supplied with blasting agent.
  • the power consumption of the blasting agent acceleration device can also be recorded indirectly by measuring a total power consumption of the blasting system. On the basis of a measurement of the total power consumption, the overall efficiency of the blasting system can also be determined.
  • beam duration time interval means a time interval from the measured actual beam duration.
  • the beam duration time interval can freely to be determined.
  • a duration of 24 hours is usually selected as the beam duration time interval.
  • a "specific point in time” is understood to mean a predetermined selected point in time. It can be, for example, the full hour in each case.
  • a mean value is formed retrospectively from the total weight of blasting agent metered during the predetermined blasting duration time interval up to the specific point in time.
  • the predetermined blast duration time interval is preferably in the range between 6 and 48 hours, in particular 12 to 36 hours, particularly preferably 24 hours. i.e. For example, a total weight of subsequent blasting agent is determined for a specific point in time "8 o'clock" during a blasting time interval of 24 hours that has elapsed up to that point.
  • the step "determining the mean consumption of blasting agent” is then repeated for the subsequent further specific points in time. i.e. the mean consumption of blasting agent is determined, for example, for the specific points in time "8 o'clock", “9 o'clock”, etc.
  • the mean consumption of abrasive is an objective measure of the efficiency of the blasting system.
  • a blasting system can be optimized using the average consumption of blasting media. The optimization can be done, for example, by selecting a blasting agent with a different grain size distribution, a different geometry of a blasting agent acceleration device and/or a different specified performance for the operation of the blasting agent acceleration device can be achieved. Apart from that, the consumption of blasting agent can now be recorded exactly. This enables timely and sufficient storage of blasting media at all times.
  • a duration of n*12 hours is advantageously chosen as the beam duration time interval, where n is a natural number. i.e. durations of, for example, 12, 24, 36, . . . hours are selected as the beam duration time interval.

  • the second weight is expediently measured immediately after the outlet opening has been closed.
  • the second weight is compared to the previously measured first weight, which was determined before the outlet opening was opened.
  • the difference between the first and the second weight results in a third weight of the blasting medium that is replenished at intervals.
  • the proposed difference measurement between the first and the second weight is robust and insensitive. It can be done, for example, by pressure cells, on which the preliminary bunker is at least partially supported.
  • the third weights can be summed over the beam duration time interval. From the sum of the third weights, the replenished total weight of blasting agent during the blasting time interval can be determined.
  • the third weights of replenished blasting agent are summed up over time, the respective sum is compared with a further quantity or weight in storage and when a predetermined minimum quantity or a minimum weight of blasting agent in storage is reached Remote data transmission causes a subsequent delivery of blasting media. This ensures that a sufficient supply of blasting agent is available at all times. An undesired standstill of the blasting system due to insufficient storage of blasting media is avoided.
