Blast Room Systems

Kushal Udhyog has gained expertise in design, manufacturing, supplying and installation of complete Blast Room Systems. These consist of a blast room enclosure, which can be of sheet metal pre-fabricated modular construction. Suitable size sheet metal main door on one side or both the sides are provided with air louvers and vision window. The blast room inside wall surface including door surface is protected against abrasion of flying abrasives by hanging/pasting suitable abrasion resistant rubber sheets. Suitable arrangements for illumination is provided by fixing halogen/metal halide lamps with protection frame. Blast rooms are normally provided with portable abrasive blasters, which are installed just outside the blast room. Spent abrasive in the blast room can be recovered in multi ways. However, some of arrangements are more common which includes semi automatic recovery (pneumatic), semi automatic recovery (mechanical) and fully automatic recovery (mechanical). The media is then conveyed by the screw conveyor to the boot of bucket elevator unit. The Bucket elevator system consists of belt and pulley arrangement with buckets mounted on the belt. The arrangement is motorised. This lifts the media and pours it into the media separator unit. The abrasive media separator unit has vibratory screen, which separates the debris form abrasive. The usable abrasive is fed gravitationally to portable abrasive blaster for recycling. Suitable dust collector is connected with blast room through ducting. The main purpose is to remove dust and fine abrasive particles from the blast room environment and collect the dust and abrasives so that the environment outside the blast room also remains pollution free. The dust collectors are divided in three major categories, viz., cyclone type, fabric bag type, and cartridge filter type.
