【摘要】 详尽介绍了气压过滤在压气吹干阶段的脱水机理。研究结果表明，压气吹干对降低滤饼水分是有效的，其降水机理主要有：空气置换作用、界面作用和压缩作用。不同粒度物料所需的最佳吹干条件不同，应根据实验确定。更多还原

【Abstract】 The paper gives a detail presentation of the dewatering mechanism of air-pressure filtration on air blowing stage. It shows that the air blowing is effcetive to lower the water content of cake.The dewatering mechanism includes air-displacement, evaporation and pressing. The best dewatering condition is depent on the size of meterials and should be determined by the tests.更多还原
