Abstract

A process and system for manufacturing gypsum wallboard that aerates, conditions, and cools a portion of the stucco used in the manufacturing process. This conditioning of the stucco reduces the amount of water needed to manufacture the gypsum wallboard which in turn reduces the amount of energy and cost needed to manufacture the wallboard. The stucco may also be pretreated with water. This process may be carried out using a conveyor that agitates a moving bed of stucco while the top surface of the bed is subject to a low pressure water spray.
