液相法工艺高强石膏粉线和蒸压法高强石膏粉线

high-strength gypsum powder production line with Liquid phase method and  high-strength gypsum powder production linewith autoclave technology

泰安杰普石膏科技有限公司，泰山石膏科技研究院，华能股份，武汉华电实业公司联合攻关项目--高强-α半水石膏中试项目经过近一年的开发研究，于2011年11月底调试完成，利用该工艺和装备生产的脱硫-α石膏，其抗折强度，抗压强度等各项指标符合2008年报批的α型高强石膏行业标准的高  级α50级别高要求。

该工艺具有如下特点：

1. 直接利用湿基脱硫石膏连续配料， 混合加热，结晶，离心脱水，干燥连续生产，配置简洁，工艺流畅，洁净化生产

2. 直接利用0.2-0.5兆帕的蒸汽，混合罐加热，反应罐加热，热水制备等环节，可以梯度利用蒸汽，节能高效

3. 设备及控制运行可靠

4. 产品质量稳定

High-strength-αhemihydrate gypsum is the brainstorm project of Tai’an Jiepu Gypsum Technology Co., Ltd, Tai Shan Gypsum Technology Research Institute, Hua Neng International, and WuHan Hua Dian Company. After one year’s research and development, the high-strength-αhemihydrate gypsum pilot project has been finished in November, 2011. The breaking strength and compressive strength of desulfurization- αgypsum produced by this production line fit for the highest standard 50-grade of the industrial standard of theαhigh-strength gypsum submitted in 2008.

The characteristics of the above technology:

1. It can achieve continuous dosing with the wet basis desulfurization gypsum directly. The contiluous production can be achieved by the dual firing, crystallization, centrilfugal dewatering and drying with simple configuration, fluent technology and clear  production.

2. The 0.2-0.5Mpa steam can achieve gradient usage with the following procedure which includes mixing tank heatin, reaction tank heating, preparation of the hot water and so on.

3. The reliable control and operation of the equipments

4. Stable production quality.
