Extensive tests have been carried out in order to evaluate the performance of different types of metal shot and mineral abrasives used in compressed air blasting equipment. The study was carried out by technical personnel with a lot of experience in industrial blasting applications, using strict parameters of coherence and objectivity in the applied procedures.
As a summary and for informational purposes, we describe below how the test was carried out.
The result provided interesting data, considering the characteristics of metallic and non-metallic abrasives, in terms of cleaning efficiency.
Small variations in the settings of the equipment considerably change the results obtained. Therefore, the technical support that users have from equipment manufacturers is very important.
