BM515E is Benmarc’s mid-term dust suppressant, designed to have a longer lasting effect on the material being suppressed. BM515E combines BM210E with a binding agent. The binding agent essentially sticks the smaller dust particles to the bigger particles, and keeps that bond for an extended period of time. Primarily used for stockpile suppression, which covers the stacking AND reclamation processes for up to 14 days, other applications include:
Stockpile feed conveyor. Point of application is last transfer point / tail end of the staking conveyor, NOT multiple application points, and NOT at the head end;
Multiple transfer point suppression. BM515E is applied at the discharge from a crusher / stockpile, where multiple transfer points are encountered en-route to the next area of processing. Nkomati as an example – crusher outlet is treated with BM515E, covering the dust suppression requirements at that point, as well as FOUR transfer points over 5km of conveyor;
Train load-out (Assmang). Original intention was to treat the ore being loaded onto the train with BM515E, to determine whether or not there would be any benefit when offloaded 900km away at Saldanha, as well as suppressing at the source. Since installation, there have been no dust issues when offloading at Saldanha, further proving the versatility and longevity of the BM515E product.
