Industries that require this process include :

Steel Fabricators
Trailers
Construction Equipment
Railcars
Oil Field Equipment
Ship Building
Wind Mill Structure
Steel Tanks

Essentially and efficient Blast Room System consists of :

Enclosure
Blasting Media Recovery & Separation System
Abrasive Blasting Machine
Operator Safety Wears
Dust Collector (Fabric/Pleated/Cartridge/Cyclone)
Optional Equipment

The modular blast room is specially ventilated and illuminated for enclosed abrasive blasting, and is a full sealed, dust tight, all steel structure. The components are prefabricated for simple bolt-together erection, with little or not job site welding required. The ENCLOSURE stands by it's own structural support without connections to the surrounding facilities. The size of the enclosure depends on
a) The size of the job
b) Number of operators
c) Adequate working space around the job.
It also influences size of the dust collector and reclaimer installation costs.

Several additional equipments are available to increase efficiency of Blast Room System. A few are:
#  WORK CAR OR TROLLEY FOR LOADING OF JOB.
#  OVERHEAD BEAM OR CRANE.
#  MORE No. OF BLAST NOZZLES TO INCREASE PRODUCTION OUTPUT.
#  AUTOMATIC MOVEMENT OF BLAST NOZZLE OR JOB OR BOTH (FOR SMALL BLAST ROOM).
#  VACUUM RECOVERY UNIT FOR COLLECTION OF ABRASIVE FROM INTRICATE PARTS / PORTION OF THE JOB.

Choice of the correct model of dust collector is integral to any closed environment blasting system. It is very essential to remove dust and fine abrasive particles from the environment of the blast chamber to maintain the efficient operation.
The Dust Collectors are broadly classified into three types.
1. Cyclone Type
2. Fabric Bag Type (Plain Bags/Pleated Bags)
3. Cartridge Filter Type

In operation, the exhauster fan on the clean air side of the collector draws dust laden air from the blast room through the fabular filter bags. Dust collects on the inner side of the bags and when the exhauster fan is turned off the bag shaker mechanism reconditions the filters by shaking most of the caked dust from inside of the bags into a dust collecting hopper.

Dust Collector / Extractor Unit

All abrasive recovery system include Three basic functions :
  01 Delivering the abrasive which rebounds off the workpiece to a central recovery point.
  02 Tranporting the abrasive from that central point to an abrasive cleaner.
  03 Removing dust, fines & other unwanted material from the abrasive before it enters the blast machine to re-use.

MECHANICAL RECOVERY SYSTEM
Consists of Bucket Elevator, Abrasive Cleaner & Screw Conveyor System

PNEUMATIC RECOVERY SYSTEM
Consists of Mini Hopper, Plenum, Reclaimer & Dust Collector

The blasting is accomplished manually by holding the gun against the work surface, which is fairly straight. The equipment being closed circuit, the spent abrasive is sucked due to vacuum created and cycled into pressure generator after passing through the reclaimer unit. Thus, the used abrasive and dust created is contained within the equipment, keeping the blasting operation dust free.
