Description:
The CGS screw classifier system is a free-standing packaged classifier for the separation of mineral grit from other solids and water discharged by grit removal systems.
The unit can be sited adjacent to the point of collection. The screw classifier system is designed to receive a mixture of grit and water by a pump rising main or gravity feed. Pumps may be of the centrifugal, positive displacement or air lift type.
A receiving header box on top of the screw classifier unit ensures the correct pattern of feed. This water/solids mixture then enters the settlement bowl of the screw classifier unit, where water level is maintained by a series of weirs. A peripheral weir removes any floating solids, and a second weir is positioned within the trough wall to scalp off those other solids that are lighter than grit.
Alternatively, a hydro-cyclone can be used as a receiver for pumped flow. This reduces the proportion of liquid delivered to the classifier, yet retains mineral particles of the specified size range. A hydro-cyclone also enhances the classification of grit particles from lighter organic solids.
Set within the settlement bowl is the inclined Archimedean screw. As the screw is rotated, settled solids are transported up the incline to above water level. The grit product is dewatered as it is elevated by the screw to a high dewatered as it is elevated by the screw to&n
