摘要： An apparatus and method for controlling the flow of a slurry is provided which includes using a constrictor valve on a mixing and dispensing apparatus. The constrictor valve includes a first guide plate and a second guide plate that are spaced a distance apart along the length of the conduit. Extending between the two guide plates, a plurality of elongate members have first and second ends engaged on the first and second guide plates. Upon rotation of at least one of the first and second guide plates, the elongate members are configured to impart pressure on, and constrict the conduit.

摘要： The present invention is an apparatus and process for cooling and de-steaming hot calcined stucco used in the production of gypsum boards or bagged plaster. The apparatus is a fluid bed stucco cooler and comprises a cooler housing having a plenum having a stucco inlet and stucco outlet. The stucco cooler includes a rotating disk in the plenum. The rotating disk includes nozzle for spraying fluid, and is attached to a rotable shaft extending from the side of the cooler also includes a fluidization pad and agitator to help to mix the air and the stucco powder to insure fluidization, prevent channeling, and prevent the stucco powder from building up on the various components. The air also forces steam from the hot calcined stucco out through an air outlet located at the top of the stucco cooler, thereby de-steaming the stucco. The stucco flows through the plenum and passes over the cooling coils, thereby cooling the stucco as it reaches the stucco outlet.
摘要翻译：本发明是用于生产石膏板或袋装石膏中的用于冷却和蒸发热煅烧灰泥的装置和方法。该设备是流化床灰泥冷却器，并且包括具有灰泥入口和灰泥出口的增压室的冷却器壳体。灰泥冷却器包括在气室中的旋转盘。旋转盘包括用于喷射流体的喷嘴，并且附接到从冷却器侧延伸的可旋转轴还包括流化垫和搅拌器，以帮助混合空气和灰泥粉末以确保流化，防止流动，并防止灰泥粉从各种组成部分组成。空气还强制来自热煅烧灰泥的蒸汽通过位于灰泥冷却器顶部的空气出口，从而使灰泥脱蒸。灰泥流经通风室并通过冷却盘管，从而当灰泥到达灰泥出口时冷却灰泥。

摘要： A gypsum slurry includes calcium sulfate hemihydrate, a set retarder in amounts of at least 0.15lb/MSF, a set accelerator, water and aqueous foam. The set accelerator is selected to provide nucleation sites for crystallization of calcium sulfate dihydrate and is present in amounts of at least 5 Ib/MSF. The water to calcium sulfate hemihydrate ratio is at least 0.95. Further, aqueous foam is added in amounts sufficient to create a gypsum board having a dry density of about 29 to about 35 lbs/ft 3 .
