Swing Table Type Airless Shot Blasting Machine Ast-750

In Blast Cleaning Technology , Table Type Machine is robust type the Top & Side Surface can be cleaned within a short Span of time by keeping the job on the Table and closing the Door.The machine is designed for automatic efficient shot blasting to de-scale and remove rust from job rotating on Rotating Turn Table. The Job is loaded on Door mounted Turn Table & fed in the Blasting Cabinet where they are blasted inside the chamber. The Job is loaded on the rotating table where they are blasted inside the work chamber (blast cabinet).

Once the machine is started, the blast wheel will come into rotation. No sooner the wheel attains its maximum speed, the shots will be fed automatically through a Soundabrator Valve operated by asolenoid valve and pneumatic cylinder opening mechanism. These shots are propelled on the rotating components at high velocity thereby blasting them. Repeat the operation on second Turn Table.

After blasting, the shots fall down inside the hopper of the cabinet and are gravity fed to the lower screw conveyor. The screw conveyor conveys the shots from the cabinet to the boot of the bucket elevator, which in turns lifts the shots and feed them to a Separator Drum. The usable shots, unusable shots (fine) and heavy dust will be filtered through the screen and unusable shots (bigger size) and other big particles will separate and should be removed through refuse pipe time to time. The shots, which have passed form screen, are subjected to an air wash system, which drains all the dust and broken shots. Only usable shots come in to storage hopper, which are re-cycled. The Fines and broken shots come to a refuse hopper and are rejected from the system through a refuse pipe. The dust collector absorbs the fine dust produced in the blast chamber.

The Dust particles generated in the system are collected in a number of filter bags in a dust collector. Clean air is exhausted through an exhaust fan. The Filter Bags are clean through by shaking Handle and the trapped dust particles falls in a dust bin and taken out for disposal from time to time. The machine has ample of safety measures to avoid any problem. Limit switches are provided at outer of cabinet, which does not permit any operation of the blast wheel unless the working door is properly closed. An emergency OFF switch is provided on the control panel, which when pressed, brings the complete system to stop during any emergency.
