We are trying to reduce dust emissions at 50 mt/hr chain crushers discharge in fertilizer plant.
Presently crushers are fed directly from oversize screens discharge trough a 5-7 meters tall chute without any restriction.
we have already improved somewhat by installing seals at discharge end transfer point to belt conveyor.
However, we need to reduce air entrainment also.
I have read about installing a feedbox with a minimum number of openings and also choking the feed to reduce air entrainment.
Could anyone of you give me more details about the specific equipment used for this purpose?
Thanks in advance
