During the shot blasting process, dust is generated inside the blastroom (blast booth), which is in air. This impairs the visibility, moreover, the dust will fall in a used abrasive, that will lead to additional load on the recovery system. This problem is solved by a dust collector. The dust collector is designed for removing dust from a working zone of the blastroom.
Specification of dust collectors: by air capacity (up 1000 to 50000 cub m/h), number and type of filtering cartridges, the installation location of the fan.
The most popular and effective filters are dry, cartridge type dust collectors, in which the incoming air flow is from the bottom part of the dust collector, dust is collecting into cartridge elements and exhausting air flow are in top, “clear” part.
Due to the use of special cartridge - filters from polyester, ensures very low rates of residual dust in exhaust air. For example, typical blasting application with steel grit has volume of residual dust not more then 3 mg/m³.
