Dust suppression is a key environmental consideration at Hunter Quarries as we continually seek a better work environment for our staff, and cleaner air for our neighbours.
Barmac Manufactured Sand (BMS) is a natural sand alternative often utilised for asphalt and concrete purposes. A coarse sand, BMS is heavily utilised in the production of asphalt, with as much as 45% of each asphalt tonne made up of BMS. It is a product in high demand.
Produced through a Vertical Shaft Impactor (VSI), the quarry rock is graded to produce the appropriately shaped angular particles.
BMS is also preferred by our concrete customers due to its reduced water absorption capacity. For this reason, Hunter Quarries prefers to supply BMS with its improved results in decreasing plastic shrinkage cracking when compared to the CMS alternative.
