What is shot blasting?

Shot blasting is a type of cleaning method used to strengthen or polish metal. Shot blasting is used in almost every industrial use that deals with metals this includes industries like automotive, aerospace, construction, shipbuilding, foundry, rail, and a lot more. The general technology used is either air blasting or wheel blasting.

Shot blasting is used in a wide range of surface treatments and cast finishing’s. With shot blasting in action streams of shots are generated and molded by blasting turbines. This is a device that makes up kinetic and dynamic type systems; they come fitted with adapting sleeves and a separate rotor. The propeller rotor is provided with blades. The quality and the performance of the shot blasting equipment purely coincide with the manufacturing design and the operating parameters of a unit. The circulation of the medium to be blasted is the crucial factor of the process. Starting from the hopper, working its way through the propeller turbine, the casting treatment, down to the separation of all contaminated abrasives till finally to the recycling part and its reuse.

Always remember that abrasive agents for shot blasting and other insufficient purity of an abrasive mixture can lower the efficiency of shot blasting. Most users fail to apply these fundamentals to the methodology for testing the shot blasting effectiveness. The importance to diagnose efficiency in shot blasting for industrial application is crucial to the effective work productivity.

The quality and the blasting agent, diversely affect the wearing of major parts of the machine component. The requirement to take account of all these factors in a specified time frame can further comprehend the methodology with shot blasting.

With every minute, approximately 453.592 kg pass through an impeller through the control cage opening where it later gets tossed of the blades.

  • 1. Impellers:When wear exceeds on the impeller segment by 1/8”, most of the abrasive tends to hit back on the blade instead of being diverted towards the throwing face component. The effect of the overall blast pattern and hotspot gets profoundly diffused causing an inaccurate aim.
  • 2. The control cage:When the wear exceeds the limit of 1/2'” or in other cases by just 1/4'”, the blast pattern gets lengthier and often causes abrasives to miss the work.
  • 3. Blades:When the surfaces of the blades get deeply grooved, it causes the channeling of abrasives that prohibits flowing across to the actual width of the blade. This, in turn, causes the pattern to get distorted.
  • 4. Tramp metal:The blast pattern and the control cage can shift or move apart when tramp metal can get wedged between a control cage and the impeller.

You can also determine the shot blasting operation and intensity by subjecting one side of the thin steel blade to shot blasting. The comprehensive results of the impact can lead a blade to have a bowed contour. This can be measured by the height of an arc and the reflecting degree of force that is imparted to a blade.

It is important to ensure that all blades are dimensionally accurate to the fittings to ensure the perfect balance.
