1. Brief introduction:

After being heated and calcined with certain temperature, natural di-hydrate gypsum is dehydrated    
 and decompounded, to get the product whose major component is semi-hydrated gypsum (CaSO₄ • ¹/₂ H₂O), that is, calcined 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 production includes five large systems: gypsum grinding system, automatic measuring system, calcination system, heat supply system, and aging& packing system. According to the client's requirement, gypsum crushing system can be added to crush large gypsum rock to be with size of 0-30 mm, and then conveyed into grinding system.

among them,the Gypsum powder ebullition furnace used in the calcining system has following advantages:
a; Small volume, large capacity
b; Simple structure, un-damageable
c; Compact structure, less land occupation, good de-dusting effect
d; Less energy consumption
e; Convenient to operate, easy to control
f; Good product quality, relatively ideal calcined gypsum phase composition, stable physical properties
g; Low capital construction investment& operation cost
 
And the This furnace uses electric energy or chemical energy generated by solid, liquid or gaseous fuels as main heat source and heat conductive oil as heat transfer medium. It adopts pipeline to connect boiler and thermal equipment into closed system. It also adopts new saving type heating way--- adopting forced circulation to heat thermal equipment. Compared with other heating equipment, it has the following obvious advantages:
a; Under low working pressure, it can obtain higher heating temperature. As a result, equipment investment cost is reduced and safety factor is intensified.
b; Heat uniformly and stably, accurately control heating temperature to avoid part heating to heated product, effectively improving product quality.
c; The heat conductive oil has no corrosion and scale, so investment for water treatment equipment which is necessary for heat transfer medium such as water or steam and pharmaceutical treatment cost is reduced.
d; The freezing point of heat conductive oil is relatively low and can be used in cold winter. Even if it is solidified, there is no expansion and no danger for cracking equipment.
e; One organic heat carrier boiler can supply heat for several users simultaneously with different temperatures. Thus the equipment investment for many heating equipments for many users is reduced.
f; Compared with steam boiler, organic heat carrier furnace can save over 40% energy, for it adopts liquid transmission to transfer energy, and circulated heating, without condensation emission to loss heat. It is the ideal energy-saving and environment-protecting products, easy to operate, safe and reliable.
