The shot blasting operating mix is of primary importance when blasting steel profiles and plates. A well-distributed mix of small and larger particles will give the best shot blasting results and is key to achieving maximum quality and output. Big particles with a lot of kinetic energy can break the upper mill skin and remove large contaminants while the smaller particles are able to reach the pores and remove the smaller and remaining contaminants. The shot blasting systems are equipped with a separator which separates the inoperable abrasive or dust from the rest of the abrasive.Without the separator the shot blasting system would be very inefficient because the operating mix would be far from optimal.
Particles decrease in size after each cycle. The larger sized particles will become medium sized particles. The medium sized particles become smaller sized particles and the smaller sized particles become dust. This is called the flaking or onion effect. The remaining dust is extracted by a fume extraction unit. When using steel shot it is required to add an average of 11 kg (24 lbs) (4 x 15 kW (20 Hp) turbines), 15 kg (33lbs) (6 x 15 kW (20 Hp) turbines) or 30 kg (66 lbs) (8 x 22 kW(30 Hp) turbines) of the larger sized (SAE J 444 - S390) particles per shot blasting hour, to keep a relatively constant shot blasting mix.
