Waste wallboard and gypsum goes through the following general processing stages: The raw material gypsum waste is loaded into a large feed hopper, which feeds the waste onto a sorting belt where a quality control agent can sort through the material to ensure suitability for the manufacturers feedstock. A conveyor belt then moves the material under an electromagnet which removes minute

Processing Gypsum into a Soil Amendment. When applying gypsum to soil, a pelletized form is ideal. Pelletized gypsum is easy to apply, mixes well with other inputs, and delivers nutrients effectively. The uniform sizing of pelletized gypsum also prevents gaps in application coverage. Gypsum Processing for Wallboard Schenck Process. Gypsum Processing for Wallboard Gypsum is a soft sulfate
Gypsum Processing for Wallboard Gypsum is a soft sulfate mineral composed of calcium sulfate dehydrate, with the chemical formula CaSO#183;2HO. It is widely used in a variety of applications and is the main ingredient in many forms of wallboard, block, and plaster products.
Throughout various stages of a gypsum wallboard processing system, drying can be attributed as a leading element in the overall quality of a final gypsum product. Considering that gypsum wallboard sales exceeded 3 billion in 2013 alone, with sales estimates projecting rising demand, it comes as no surprise that every stage of gypsum processing must be efficient in order to ensure consistent
Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard. To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 #189;H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and
Basic Steps when Processing Gypsum into Gypsum Wallboard. Gypsum wallboard, commonly referred to as drywall or gypsum board, is a specific building board material containing a gypsum core and paper exterior. While typical gypsum processing produces crude and finished products throughout the various processes, the following outline highlights stages performed during the manufacture of gypsum

Raw gypsum ore is processed into a variety of products such as a portland cement additive, soil conditioner, industrial and building plasters, and gypsum wallboard
Gypsum waste can be turned into recycled gypsum by processing the gypsum waste in such a way that the contaminants are removed and the paper facing of the plasterboard is separated from the gypsum core through mechanical processes including grinding and sieving in specialised equipment. Gypsum waste such as gypsum blocks and plaster do not require the removal of paper, as they are
Gypsum can be a difficult material to process, from its variability, to its tendency to harden into a cementlike form, and its abrasive nature. For this reason, choosing processing solutions that are heavyduty and designed around the unique characteristics of the gypsum

to becoming gypsum wallboard paper. The process begins when the waste paper is fed by conveyor into a pulper. The pulper is like a giant blender that dissolves the old paper into a soup, or slurry, of paper fiber called pulp. From the pulper, the slurry goes through a cleaning system where contaminantssuch as bailing wire, staples, glue and inkare removed before the pulp goes into the
