ABSTRACT:
An apparatus for controlling the flow of water to a pug mill. A water supply system is connected to the pug mill for providing a flow of water to the pug mill. The water supply system includes an inlet line connected to a supply of water; a pump connected to the inlet line; an outlet line connected between the pump and the pug mill; a return loop connected between the outlet line and the inlet line; and bypass means for selectively controlling the flow of water between the pug mill and the return loop. The invention also includes a control system having a moisture sensor for providing a signal representative of the moisture level of the clay feed material. A flow transmitter is located between the water supply and the pug mill for providing a signal representative of the water flow to the pug mill. A control valve is located between the water supply and the pug mill for controlling the flow of water to the pug mill. A controller is connected between the moisture sensor, the flow transmitter and the control valve for receiving the signal representative of the moisture level of the clay feed material and the signal representative of the water flow to the pug mill and providing a control signal to the control valve to control the flow of water to the pug mill.
