After shot blasting in the chamber (80% of the exterior) the car is supplied to the shot peening area, where the exterior and interior shot peening is made. The media collecting (during the interior cleaning) is made by vacuum media collecting system. The used media falls through the grating floor to the chain conveyors, which gather it to the center of the chamber, where cross conveyors area is located. Then media goes to the standard media cleaning system and to the shot peening machines.The shot peening chamber operators are equipped with full set of personal protective clothes and breathing air supply systems. Depending on season the climate system has two breathing air preparation modes, which means heating or cooling. The chamber operating space is equipped with lifting operator’s platforms where needed to facilitate the metal structures cleaning in height.
