Machine Learning for Soft Sensors and an Application in Cement
Soft Sensors are predictors for measurements that are difficult or impossible to obtain by means of a physical sensor. A soft sensor delivers virtual measurements based on several or many physical measurements and a mathematical or numerical model that Due to high energy consumption in cement grinding processes and unavailability of reliable hardware sensors for continuous monitoring, soft sensors have tremendous scope of application in cement mills. Modern cement plants are increasingly using vertical roller A hybrid soft sensing approach of a cement mill using

A soft sensor model based on long&short-term memory
A cement mill is an important industrial equipment for converting cement clinker into finished cement products. The cement mill system consists of two parts: a coarse grinding system based on roller presses and a fine grinding system based on ball mill. Fig. 1 shows a schematic diagram of the variable composition and production of a cement millIn 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 Ventilation Prediction for an Industrial Cement Raw Ball Mill

Developing a soft sensor for fineness in a cement ball mill
Abstract. One of the important requirements in finish milling is maintaining consistent product quality. Quality of cement is measured through blaine which is a measure of the specific surface area or the fineness of cement. Since process adjustments are made based on this quality measurement, infrequent sampling may result in production lossSpecifying a Vibration Sensor. Cement manufacturing is one of the most demanding industrial environments, with high concentrations of dust, extremes of temperature and severe mechanical stresses on operating Cement Industry Hansford Sensors
