Airless Shot Blast Cleaning uses motor driven Blast Wheel rotating at high speed. The shot is propelled by this blast wheel, which uses radial and tangential forces to impart the necessary velocity to the shots. The position of the wheel from which the shot is projected is controlled to concentrate the blast in the desired direction. Among the advantages of the wheel method of propulsion are easy control of shot velocity, high production capacity, and freedom from the moisture problem encountered with compressed air.
As part of this technique of blasting, a controlled stream of abrasive shot material is propelled towards the metallic or steel surface that needs to be shot blasted with. There is a blast wheel that is located at the heart of the machine. As soon as the rotation of the wheel starts, the metallic abrasives or the shot media are channelized towards its centre. From this position onwards, the abrasives are accelerated and hurled into the direction of the surface which is being prepared for finishing.
After the completion of this process, the contaminants as well as the media make a rebound into a separation system which contains the dust collection system. Just like the name suggests, the dust collector is responsible for collecting dust. The remaining media gets recycled by bucket elevator and transferred into media separator where correct media is segregated & return it to the storage hopper where the particles can be kept as buffer stock for using them in the continues cycle .
