Soft Sensor for Online Cement Fineness Predicting in Ball Mills
This paper describes the design and implementation of a soft sensor based on a backpropagation neural network model to predict the cement fineness online in a ball mill. The input variables of these models were selected by studying the cement grinding process, applying Spearman's rank correlation, and the mutual information (MI) algorithm.

Mill control using millScan g4
Fixed position sensors are able to detect changes to 1/10th of a per cent in fill level accuracy which then equate to +/- 0.01 mA on the 4-20 mA fill level output signal fed back to the control room. The shell based sensors are typically not as accurate but still far superior for mill control than a microphone based system.
