某水泥厂生料车间有2台φ2.2m×6.5m生料球磨机,在运行中出现磨头漏料现象,使磨机的产量和质量大幅度下降,而且增加了工人的劳动强度。该厂先后采取了许多措施,效果都不理想。1原因分析采取逐一分析排除法进行检查,发现造成磨机磨头漏料的主要原因为:(1)物料水分大对进磨物料进行化验,粘土水分在10%左右,石灰石、煤、铜矿渣的水分均大大超过表1中的规定值。(2)通风不良磨机原采用自然通风方式,即靠磨尾排气筒两端自然压差排出磨内气体,因物料在出
A cement plant raw material workshop has 2 sets of φ2.2m × 6.5m raw material ball mill, the mill appeared in the leakage phenomenon, so that the mill output and quality dropped significantly, but also increased the labor intensity of workers. The factory has taken many measures, the effect is not satisfactory. 1 Analysis of the reasons to take one by one analysis exclusion method and found that the main cause of grinding mill head leakage is: (1) material moisture large on the grinding material testing, clay moisture is about 10%, limestone, coal, copper Slag water greatly exceeded the value specified in Table 1. (2) poor ventilation of the original natural ventilation mill, that is, by the tail gas exhaust at both ends of the natural pressure discharge mill gas, due to the material out
