Gypsum boards or plasterboards are typical materials used to build light walls. The production process is based on gypsum hydration technology. At the very beginning of the process dehydrated calcium sulfate (gypsum) is converted into CaSO 4 · 2 O by heating. Once dehydrated, gypsum is mixed with water, starch, a ing agent, and other additives.
A gypsum composition including gypsum, water, and a surfactant composition of alkyl sulfates of formula H(CH 2 ) n OSO 3 − M +, in which n is from 6 to 16, the mean number of carbon atoms in the alkyl sulfate composition n m being between 10 and 11, and M is a monovalent cation. A process for the preparation of the gypsum composition and a gypsum board obtainable from this composition.
Process description Gypsum boards are manufactured using 95 wt% waste gypsum board. The resulting 5 wt% comes from rejected gypsum boards from this process, because the boards did not met the requirements. Until now only up to 30 wt% of recycle material is used as feed for new gypsum .
Recycling Process. New West Gypsum Recycling receives preand postconsumer gypsum waste, reconstitutes the materials into useful products and provides the raw material for new manufacturing. Our successful business model incorporates agreements with wallboard manufacturers that secure a strong supply and demand for the gypsum material.

Gypsum Board production flow "Tiger Board" is produced in the factory automated production line. Let''s see the manufacturing process. 1. Calcination process "Gypsum" is baked in a furnace and made into "calcined plaster" which will solidify when it reacts with water.
While gypsum board is easy to recycle, finding recycling facilities for gypsum board can be difficult. The paper exteriors and gypsum cores of gypsum board can be made from high percentages of recycled material, but this results in limited to no energy savings because it must go through the manufacturing process .
Gypsum board is one of many gypsum panel products, defined in ASTM C11, Standard Terminology Relating to Gypsum and Related Building Materials and Systems, as "the general name for a family of sheet products consisting essentially of gypsum." This term includes gypsum board, glass mat gypsum panels, abuseresistant, and impactresistant ...
Manufacturing process: Gypsum is Disc Pulverized after drying. These are calcined in Rotary Drum Calciner at 140?C to 170?C for about two hours. After cooling the plaster of paris is pulverized again to a mesh of 150. The fine plaster is mixed with colouring material and then made into slurry by adding water.
With our own manufacturing facilities, Gyptech is capable of in house equipment fabrication. Close collaboration of highly experienced gypsum professionals working as a team from design through the entire manufacturing process, results in excellent quality assurance.
The process to produce gypsum board generally consists of calcining and or grinding gypsum powder, forming a gypsum panel product and drying off excess water. Innogyps has prepared a training presentation that introduces the gypsum board manufacturing process in detail including:
forming section of the manufacturing process Stucco – Wet End Manufacture Gypsum wallboards'' major ingredient is calcium sulfate hemihydrate, stucco. Stucco is manufactured from natural rock or from a synthetic source by: Drying The crude gypsum rock is put through a kiln to remove excess water that was common from the source
of the manufacturing process. The stucco is blended with water and other ingredients (depending on the type of wallboard being made) to make a "slurry," or paste. This stucco slurry will then be spread onto paper to form wallboard. The "Bread" That Makes the Wallboard Gypsum wallboard is frequently described as a "sandwich," with gyp
