In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)".

However, strongly nonlinear, dynamic timevarying, and multirate data characteristics are major causes of poor soft sensor performance. To address this problem, a strategy of building a soft sensor model based on local semisupervised ensemble learning of least squares support vector regression (LSELLSSVR) is proposed in this paper.

1. Introduction. A realistic simulation of charge motion in autogenous (AG), semiautogenous (SAG) and ball mills is desirable since such a study would shed light on shell wear, ball wear and mill capacity besides the much sought after power draft. Measurement of charge motion with sensor has yielded very little information and sophisticated ...
