What operating conditions have to be present in order to benefit from using the CONVAC system?
The operator must be able to maneuver the dredge to keep excess pumpable solids constantly available at the suction pipe inlet. In other words, there must be more pumpable solids available at the suction inlet than are needed to satisfy production requirements. This means that the dredge should have a cutterhead or chain ladder digger and the appropriate equipment needed to maneuver the suction inlet to keep it in contact with the solids bank.
