Shot blast machines suitable for the mechanical descaling of coil wire.
Wire coils to be processed are supported by two arms, rotating on their own axis and alternatively transported into the blast room, where multiple shot throwing wheels give complete coverage of the wire.
The arm-holder door is suitably protected with high resistant manganese linings. The door supports two geared motors which control the rotating movement of the coil supporting arms.
The arm rotation inside the blast compartment is programmed to guarantee the best exposure of the wire coils to the abrasive action.
The outside arm rotation can be controlled by the operator. The diametrically opposed arm arrangement allows simultaneous cleaning operation of the coils in the blast zone and loading/unloading outside the chamber.
