The invention provides a process for producing highstrength alphagypsum from chemical gypsum by adopting a dry method. The process comprises the following specific steps of: placing a chemical gypsum as a raw material in a mixing machine, and spraying a mixed aqueous solution of a crystal modifier of sulfonate and maleic anhydride on the surface of the chemical gypsum raw material while ...
The largest gypsum quarry in the world, Gold Bond's Milford, Nova Scotia operation, produces four and a half to five million tons of ore per year. The quarry process begins by first removing the earth over the deposit. Then gypsum ore is drilled and blasted loose to be carried to the processing plant, where it is crushed and screened.
Hammer mills are used for crushing mediumhard and soft materials (coal, limestone, gypsum, clay, marl, salts, phosphates, etc.). The processing of feed material with increased moisture is also possible in CPC hammer mills. Grinding drying by feeding hot process gas ( flue gas from a combustion) into the hammer mill.

A gypsum board includes a set gypsum core and front and rear paper facers adhered thereto. At least the front paper facer has substantially isotropic tensile strength, thereby providing the gypsum board with enhanced nail pull resistance. A process for manufacturing such gypsum board is further provided.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and massive finegrained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including ...
