Description

ABSTRACT:
A wetting apparatus and method for mixing water with a powdery dust generated from a foundry or other operation. In order to prevent dust from becoming airborne, and thus an environmental nuisance, it must be wetted before disposal. The wetting apparatus includes an elongated housing, a mixing screw, and a spray system in addition to inlet and outlet gates for metering the dust. The mixing screw load may be used to control water, while the weight of the dust itself may be used to meter its input into the housing. Alternatively, a moisture sensor or indicator for automatically controlling the quantities of dust and water may be used.
