Cement production is one of the most energyintensive manufacturing industries, and the milling circuit of cement plants consumes around 4% of a year's global electrical energy production. It is
The cement plant of the future achieves considerably lower operating costs and higher asset value through higher energy efficiency, yield, and throughput. More targeted and effective maintenance lengthens the lifetime of equipment. Our reference plant is a fivestage preheatercalciner kiln with a vertical raw mill and two cement ball
For typical circuits that involve AG/SAG, HPGR or ball milling, the generation of 75 µm material (denoted as SSE75) is a suitable marker size with which to benchmark performance because it contains 80% of the surface area generation 1 and energy is proportional to surface area generation 2. As shown in Figure 1, whereas the

The direct CO2 intensity of cement production increased about 1.5% per year during . In contrast, 3% annual declines to 2030 are necessary to get on track with the Net Zero Emissions by 2050 Scenario. Sharper focus is needed in two key areas: reducing the clinkertocement ratio (including through greater uptake of blended

The grinding action in a ball mill is a purely random process. Ball mills are normally operated at around 65 75% of critical speed (Alsop, ; Gupta and Yan, ). Optimisation of electrical energy in cement ball mills helps in increasing mill efficiency and effectiveness. 2.2 Theoretical Background
Grinding of clinker is the last and most energyconsuming stage of the cement manufacturing process, drawing on average 40% of the total energy required to produce one ton of cement. During this stage, the clinker particles are substantially reduced in consisting of a tube ball mill and a high efficiency separator was introduced through
