一、问题的提出临安膨润土矿建矿几十年以来,一直采用在雷蒙机粉碎室直接加热风干燥的工艺。从1983年来的质量检验证明:同样的原矿,经加工成品后,质量相应地有所下降,特别是湿压强度下降0.04～0.1kg/cm~2,热湿拉强度一般下降1～5g/cm~2,见表1。表1中系钠基土,每组对应相同原矿。原

First, the issue put forward Lin’an bentonite mine construction for decades, has been used in the Raymond crushing chamber directly heated air drying process. The quality inspection from 1983 shows that the same raw ore has a corresponding decrease in quality after finished products, especially the wet compressive strength is reduced by 0.04 ~ 0.1kg / cm ~ 2, the hot wet tensile strength is generally reduced by 1 ~ 5g / cm ~ 2, see Table 1. Table 1 Department of sodium-based soil, each group corresponds to the same ore. original
