US 10,907,898 B2 · Aggregate dewatering device and method

Abstract

A dewatering device for aggregate product can be used to retro-fit existing aggregate product dewatering facilities in order to more efficiently capture product. The dewatering device can be movable to allow for the portability of the device relative to existing dewatering facilities. The device is adapted to receive a slurry of aggregate product and water and to vibrate to dry the aggregate product. A recycle system is included to receive any fines that may otherwise be lost by the system. The recycle system captures the fines and redirects them back towards the vibrating process of the vibrating device to direct them towards an exit of the vibrating device in order to use said fines as well as the other dewatered aggregate product. The portability of the device allows the device to be used with the existing facilities without the need to completely replace existing components for dewatering aggregate product.

Dependent claims

A dewatering device for aggregate product, comprising:

a vibrating screen for receiving aggregate product from a screw conveyor, the vibrating screen having an entrance disposed to receive aggregate product, said vibrating screen including a vibrating system to move said screen;
and
a recycle system positioned at least partially below the vibrating screen to receive fine materials passed through the screen and to aid in directing the fine materials back to the entrance of the vibrating screen, wherein the recycle system comprises:
a reservoir member disposed to receive fine materials passed through the screen;
and
a redirection apparatus comprising:
a first inlet, the first inlet disposed to receive fine materials from the reservoir member;
a second inlet, separate from the screw conveyor, the second inlet configured to receive a fluid from outside the reservoir member;
and
an outlet at or near the screw conveyor, wherein the fine materials from the first inlet and the fluid from the second inlet are combined in the redirection apparatus and dispensed via the outlet into the screw conveyor.
