ABSTRACT:
A dewatering method and apparatus is disclosed which uses a ramp at one end of a perforate conveyor in which the incline of the ramp may be adjusted while the dewatering operation is taking place. The ramp receives material to be further dewatered after the material has moved along the length of the perforate conveyor. The ramp causes the material to roll back upon itself as the material tends to move up the ramp, which rolling back action enhances dewatering. An actuator is coupled with said ramp for effecting movement of said ramp with respect to the conveyor to adjust the incline of the ramp with respect to the upper surface of the conveyor. In this way, the operator may readily optimize the rolling back action of the material to be dewatered to, in turn, thereby provide optimum dewatering. The ramp is also capable of being completely lifted out of the flow of material to be dewatered while the apparatus is in operation and while the dewatering process is being carried out.
