NuGyp™ Process
Process Overview
The process exposes the freshly calcined plaster to steam at pressures above atmospheric for specified times.
The equipment for the NuGyp LoCal Process is a pressure vessel into which a measured volume of freshly calcined plaster is fed. The chamber is sealed and live steam is injected. The time of exposure and the pressure used dictate the level of water reduction achieved.
At the end of the treatment time, the steam supply is closed, the pressure in the chamber is vented and the treated plaster discharged.
Typically, steam pressures of 40 psig to 80 psig and treatment times from 30 seconds to 3 minutes are used, depending on the reduction in water demand desired.
