Sand recovery
Making its debut in Canada, a portable sand recovery unit is delivering increased asphalt blend sand output and other improvements for an Ontario aggregate producer.
The new unit went into production last August at the Norwood, Ontario, sand and gravel pit of Drain Bros. Excavating. The pit supplies significant aggregate volumes to the company’s construction, asphalt and utility divisions as well as the Peterborough market 35 km to the west. The new wash plant was acquired to increase the recovery of asphalt blend sand fine fractions, previously being lost to the pit’s settling ponds. The improved material recovery translates into increased output of asphalt blend sand for the company’s pit-based hot-mix asphalt plant, an overall increase in wash plant capacity and reduced settling pond maintenance costs.
The Finesmaster 120 sand recovery unit from Powerscreen, Louisville, Ky., combines twin bucket wheels, twin hydro cyclones, a collection tank, a dewatering screen and a centrifugal slurry pump on a single chassis.
