Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding. Mine-to-mill optimisation: effect
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1 % per annum. The electrical energy consumed in cement production is approximately 110 kWh/tonne, and around 40 % of this energy is consumed for clinker grinding.

This paper explores the use of process integration techniques to improve the energy efficiency of cement plants, focusing on the dry route cement production and the integration of alternative fuels. Flow sheeting modeling, Pinch Analysis and mixed integer linear optimization techniques are applied to study an existing cement production facility.
Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding take place within the body of the mill. Normal VRM control strategies Product fineness

The paper presents the design procedure of a model-based control algorithm for the regulation of tailings and product flowrates in a cement mill. The control variables are the feeding rate and the classifier speed. Experimental results of a full-scale industrial application are reported and discussed with a view to the control of the fineness of the cement.
