当入磨生料的水分过大时,通常的窑尾热风已经不足以烘干原料,即使把窑头热风引入也不能满足,这就要增加额外的热源来满足要求,在线热风炉因此应运而生。我们在尼日利亚EWK项目上,使用了在线热风炉,较好地解决了高湿黏物料的烘干问题。1原料情况尼日利亚EWK是5000t/d生产线项目,位于拉各斯北部65公里。该地区雨量充沛,且雨季长,从四月份一直到十月份,如此大的雨量导致原材料含水量较高,如黏土平均含水量28%,入磨生料15%。只使用窑尾热风已不能满足烘干要求,即使是将窑头热风引
When the raw material into the water is too large, the usual kiln hot air is not enough to dry the raw material, even if the introduction of kiln hot air can not be met, it is necessary to increase the additional heat to meet the requirements, so the hot air oven should be transported Health. We use the online hot blast stove on the EWK project in Nigeria, which solves the problem of drying the high-viscous materials. 1 Raw material situation Nigeria EWK is 5000t / d production line project, located 65 kilometers north of Lagos. The region has abundant rainfall and long rains. From April until October, such heavy rainfall leads to high moisture content of raw materials, such as clay with an average moisture content of 28% and mill-in raw materials of 15%. Only use the kiln hot air can not meet the drying requirements, even if the kiln hot air lead
