New sand-recovery unit from Powerscreen
Powerscreen’s Fines Master 120 has been designed to produce one or two grades of sand up to a maximum of 120 tonnes/h. The unit combines a twin bucket-wheel, a centrifugal slurry pump, twin hydrocyclones, a collection tank, and a 12m x 5m dewatering screen, all on a single-carrier chassis.
The recovery unit’s high-capacity twin bucket-wheel has variable-speed controls, recovering 80% of the product to the dewatering screen. The specially designed inlet boxes reduce turbulence at entry to the bucket-wheel tank while the weir discharge system reduces the volume of fines entering the cyclone collection tank.
The twin 380mm rubber-lined hydrocyclones discharge via an adjustable chute which allocates the recovered materials to either the coarse or fine product split on the dewatering screen. The 12m x 5m high-frequency dewatering screen is fitted with 500µm polyurethane modular mats. The underflow slurry pump is rubber lined.
