1. Gypsum powder quality standard: in compliance with GB/T 9776-2008 2. Main Technology(here take Nature gypsum rock as example) Gypsum rock - first crushing -second crushing - grinding - calcining - aging -finished products (CaSO4.1/2H2O) After being heated and calcined with certain temperature,natural dihydrate gypsum is dehydrated and decompounded,to get the product whose major component is semi-hydrated gypsum(CaSO4.1/2H2O),that is,calained gypsum(generally slaked gypsum).According to different temperatures and pressure conditions during dehydration decomposition,the obtained product is β-Type calcined gypsum.Basic process of mechanized prouduction includes five large systems:gypsum grinding,automatic measuring system,calcination system,heat supply system,and aging&packing system.According to client's requirement,gypsum crushing system can be added to crush large gypsum rock to be with size of 0-30mm,and then conveyed into grinding system. 3.Payment conditions: A. Payment terms: 30% T/T in advance; 70%L/C or T/T B. We can provide quality guarantee; C. Kunlun bank account available to make convenient for Iranian client National Standard of Calcined Gypsum Standard No.: GB/T 9776-2008 Scope of application: Gelled material made by dehydrating natural gypsum(raw material). Its main component isβ-GaSO4·1/2H2O, without any admixture or additive. The natural gypsum should be in conformity with requirements of "gypsum rock(JC/T700) for making cementing material" gypsum rock of Grade 3 or more higher grades. Classification: It is classified to be three grades: 3.0,2.0,and 1.6 according to its 2h strength(breaking strength). Composition: β-GaSO4·1/2H2O content(mass fraction) in Calcined gypsum should be not less than 60.0%.
Chemistry gypsum powder production line:ªG building gypsum powder. Chemistry gypsum is refers to the industrial production process, forms industrial products, such as desulphurization gypsum, phosphorus gypsum, fluorine gypsum, lemon gypsum and so on.Raw material characteristic:the surface water is more than 20%, the ingredient relative is unstable. Building gypsum powder production technology introduction: Uses raw material pre-drying , bolling stove calcine that two step calcine technique of production, use car loader to transport raw material from dump site to material basket, by beater, the belt conveyer to transport uniformly to the dryer(the heat source of this place is that burn coal the hot-blast stove), though collection powder equipment vertical transmisslon equipment brought into boilling stove calcined(that furnace heat is the htf stove), after calcination shipped goals mushroom grinding machine modified and cooling, and from promotion transportation to the warehouse, packaging warehouse.

When heating and calcining the dihydrate gypsum, the dihydrate gypsum will be decomposed, we can produce the semi-hydrated gypsum (CaSO4?/2H2O) , that is building gypsum, also called plaster of paris. Because of the different temperature and pressure when decompose the gypsum, we can get different product, a-type gypsum and b-type gypsum. a-type gypsum is high-strength gypsum,b-type gypsum is building gypsum. They are the same technology using mechanisation producing building gypsum. The process can be divided into three system, crashing system, calcining system and milling system. Wooden case & plaste
