Indirectly heating type is mainly suitable for the material with long period of decreasing-speed drying and heat-sensitivity, such as phosphorus fertilizer, congruity clunch and phosphor plaster.

间接加热型主要适用于降速干燥阶段较长的物料和热敏性物料的干燥如：硫铵、有机晶粒、沥青土等。复合加热型主要适用于粉状及较轻物料的干燥如：磷肥、调和粘土、磷石膏等。

But the result of improvement soil translated alkaline soil into alkalier soil. Not onlu it is unavoidable and subsisted of stabilization in commix tier of gypsum, but also it destroyed direct improvement process. It is imported find what solved seepage problem of gypsum in the study. In configured duality structure of improvement soil, it needs abundance seepage gypsum in commix tier into noncommix tier in order to losing seepage capacity reduce in all deepness of improvement soil.

碱土改良过程中石膏渗漏损失最高可达到石膏施入量的40%以上，而改良结果碱土只转化为重碱化土；在石膏混合层内，它是一种不可避免的、稳定存在的且直接破坏土壤改良进程逆流；因此解决石膏渗漏问题亦是在本文研究工作中的重要发现：配置二元结构改良碱土中，正需要石膏混合层中大量石膏渗漏，以改良非石膏混合层，并使整个计划改良深度内的渗漏损失降为零。

Raymond Red Star machines widely used in production of barite, calcite, potash feldspar, talcum, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, swelling earth, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, etc. Mohs hardness is not greater than 9.3 and humidity below 6% of non-inflammable mineral, chemical and construction industries more than 280 kinds of materials of high fine flour processing, particle size 80-325 mesh finished products within the scope of arbitrary regulation, part of the material up to 600 mesh.

The results showed that under a given delayed coagulant , water retentiveness and cohesive strength of stucco gypsum mixed with modified bentonite were higher than that of methyl cellulose .

试验表明，在缓凝剂掺量一定时，单掺改性膨润土的粉刷石膏加水拌合后，其保水性，强度和黏聚性等各项性能指标，均优于掺有甲基纤维素的粉刷石膏，文中还对保水机理进行了分析。

Correlation analysis showed that: medicago sativa various physiological indicators and the application of gypsum both have a good correlation, so gypsum on the coastal saline soil in the development and use of a very important role and significance.

相关性分析表明：苜蓿各项生理指标与脱硫石膏的施入量均有很好的相关性，因此脱硫石膏对滨海盐渍土的开发和利用有很重要的作用和意义。

ABSTRACT Mechanical properties of soil stabilized cement made from kiln ash, which consists of clinkers made from kiln ash only or the kiln ash with CaSO4-CaF2 compound mineralizer and certain amount of gypsum are studied. Moreover, the effects of burning temperature and gypsum content on the strength of the stabilized soil with kiln ash cement have been researched.
