一、引言预加水成球是水泥工业近年来推广应用的新技术。该技术是将水泥混合生料粉与水预先在搅拌机内混合,再传送到成球盘内滚动成球,这项技术,在工业环境多变和存在无法预测的干扰条件下由人工直接操作很难驾驭。因此,应庆安县水泥厂要求,我们研 I. INTRODUCTION Pre-add water into the ball is the cement industry in recent years to promote the use of new technologies. The technology is the raw material of cement mixed raw meal mixed with water before mixing in the mixer, and then sent to the ball into a ball rolling into a ball, the technology, in the industrial environment and unpredictable interference with the environment by the direct manipulation of artificial Difficult to control. Therefore, Qing’an cement plant requirements, we research
