The fine particles generated in polishing and grinding is hardly to avoid even with the most advanced technologies.
In addition to polishing dust, paste, materials such as scrubbing fleece (cotton, other), and by-products of abrasion are siphoned off. Due to these dust are flammable and explosive, fire and explosion protection design must be contained.
Dust removing can be designed dry or wet separation based on your actual requirements.
For dry separation processes units in the Pulse Jet cartridge de-duster series are recommended.
Cartridge filters and additional secondary filters are utilized if purified air is recycled back to the workparts. The lifespan of a fliter can be extended if using cyclone system for pre-separating of coarse dust particles.
A dosing unit adds limestone powder to decrease the fire and explosion danger during dry separation. Further explosion protection measures can be cut out, however the mixing ratio should remain at 9:1.
Nevertheless, investment for wet separators in the wet scrubber series are most valuable.
The majority of customers utilize wet scrubber to solve metal polishing dusts, which results in an ideal emission, as the fine dust with particular gravity the water to be a filteration plays an economical role who can collect the dust sufficiently.
