Dust control & emissions
Baghouse and dust control
Bag filters and local extraction that keep dryer exhaust and plant dust under control.
The dryer exhaust carries fine dust. A primary separator removes the coarse part, then bag filters capture the fines before the exhaust fan sends clean gas to the stack. Collected dust can return to the mix as filler.
Dust from the screen, scales and filler transfer is captured by local hoods and ducts. Bitumen fumes are a different problem: a baghouse removes particles, not fumes or odour.
How it works
- 01
Primary separation
Coarse dust drops out of the exhaust stream.
- 02
Bag filtration
Filter bags capture fine particles.
- 03
Bag cleaning
Pulses of air knock the dust off the bags.
- 04
Exhaust
The fan draws gas through the system and out of the stack.
- 05
Dust handling
Collected fines go to the reclaimed dust silo.
Common configurations
Stationary baghouse
Beside the tower for fixed plants.
Trailer-mounted baghouse
For mobile plants.
Local extraction
Hoods and ducts at screens, scales and filler transfer.

Questions
Does a baghouse remove bitumen fumes?
No. It removes dust particles. Fumes from tanks, the mixer and truck loading need their own capture and treatment if your permit requires it.
