Blasting operations in which dry ice pellets are pushed onto a workpiece at high speeds. Beskrivning The process Ice pellets [1] is supplied to a compressed air mixing chamber [2] and pushed out at high speed through the nozzle onto the workpiece. When the pellets hit the contact surface it freezes and a thermal shock occurs in the surface contamination, which results in raised that shear stresses. This will release the contaminants which are removed using pressurized air.
