Simulation of open circuit clinker grinding - ScienceDirect

A mathematical model has been developed for an open circuit two-compartment tube mill grinding cement clinker. Samples were collected of the feed and product, and inside the mill. In the laboratory, sizings were done between the top size and 2 μm, and the breakage distribution function of the clinker was obtained by using a twin pendulum apparatus.

[PDF] Cement grinding optimisation Semantic Scholar

Abstract 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. There is potential to optimise conventional cement clinker grinding circuits and in the last decade significant ...
