cement mill ball charge and cement fineness

Soft Sensor for Online Cement Fineness Predicting in Ball ...

Keywords: Cement fineness, artificial neural network, ball mill, product quality. 1. INTRODUCTION Cement is a powder material, forming a paste with water, that hardens due to hydration reactions, creating strength and durability. The cement fineness is monitored and controlled during the grinding process to obtain the desired
