Transformer Casing Shot Blasting Machine (Automatic)

Surface International has recently introduced a 3-blast wheel closed loop overhead conveyor type shot blasting machine, which is especially suitable for high volume cleaning of fabricated transformer casing with fins having overall size 1500 x 1000 x 1600 mm height having 500 kg weight. This is also suitable for high volume efficient blast-cleaning of forged/cast components. The machine is fully automatic, PLC controlled with rotary screen separator, overhead conveyor system, pneumatic cylinder operated doors and reverse pulsejet dust collector. It can be operated by just one person, required to load/unload the material at loading/unloading stations. After loading, the entire operation is performed automatically, and the only manual intervention is after the operation is over, for unloading. The PLC provides an annunciation system, which provides online information of the processing being done by the machine. Various safety norms as required by such sophisticated machine are in-built in the system, i.e., the doors of the machine get opened when the feed of shots to blast wheel is stopped. The blast wheel runs only when the dust collector is in operation. If the component is not loaded on any hanger of overhead conveyor, the conveyor does not stop at the blasting station and passes the blast cabinet at high speed thereby saving lot of precious time and energy on the one hand and protects the machine from unnecessary wear and tear on other hand.
