In Blast Cleaning Technology Air or Pneumatic Sand blasting Machine is used in Foundries for Primary fettling of as cast jobs , Surface preparation in Fabrication Industries , Surface Cleaning of various other components in Aeronautical and Defense Industries including Ships after sailing in dry docks.
The power pack unit will consists blast generator. The abrasive will be filled at the top of machine when machine is not working and blast generator is not pressurized. At the top a vibrating sieve will be provided to sieve the abrasive filled. The oversize abrasive and debris will be retained on the screen, thus prevent the choking of blast line. When mushroom valve is opened the abrasive will get transferred to blast generator for recycling. The mushroom valve gets closed when compressed air is switched on and abrasive storage tank gets pressurized, for free fall of abrasive into mixing tube. From mixing tube the TheBlast Generator will be fabricated from MS Steel plate of thickness not lessthan 6 mm as per IS- 2825 and it will be hydraulically tested for 250 PSI.
