1.Production scale:

10,000--200,000 MT/Year

2.Raw Material:

Content of CaSO4. 1/2 H2O in gypsum mine 80%

The grade of mine and the crystal configuration will influence the quality of semi-hydrated gypsum

3,Working principle

The main working principle for calcining system, of calciner

The main body of calciner consists of fine diameter intensive radiator pipes. Thermal oil fed into the coil pipes. The heat releases into power by heat exchanger. Roots blow installed at bottom of calciner for putting the cooling air into furnace by grid plate. the cooling air blows gypsum power in furnace for reaching boiling state. at certain temperature , the calcined gypsum power will lighten, and flow automatically to outlet. this type gypsum power is state in quality. it is easier to control the content of free water ,initial and final setting times.

Moreover, our equipments adopt dry electric precipitator, dust collection efficiency is over 95%
