Shot Blasting Machine, 3 Blast Wheel Hanger Type

Surface International has recently introduced, designed and manufactured a 3 blast wheel closed loop overhead conveyor type shot blasting machine which is especially suitable for high volume cleaning of fabricated/forged/cast components. The fully automatic machine is PLC controlled with rotary screen separator, overhead conveyor system, pneumatic cylinder operated doors and reverse pulsejet dust collector. The customer needs only one operator to handle this machine, to load/unload the material at loading/unloading stations. At loading station the components are loaded on the conveyor of the machine. Operation: before entering the blast cabinet on a conveyor, the components are sensed at the entry point and at each of the three blast stations, the pre-set process takes place, every time the doors of the respective blast chamber opening and closing accordingly. The machine can handle rotating drums of size 1850 and 1600 mm long. The weight of the components can be up to 500 kg. The machine can be suitably designed to undertake bigger/smaller and heavier/lighter components as per customers? needs. The PLC provides an annunciation system, which provides online information of the processing being done. Various safety norms 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.
