In terms of mill type, the answer is almost always vertical roller mills (VRMs). Over the last few decades the industry has been gradually moving towards the use of VRMs for both raw and cement grinding, due largely to the reduced energy consumption compared to ball mills: a saving of between 30 and 50%.

Re: CLINKER FROM ROTARY OR VERTICAL SHAFT KILN. There are a number of reasons why the clinkers might differ, but buying clinker from a VSK would not be a completely wrong move. It would depend on the degree of combination of the clinker, the lime saturation and the silica modulus. There are at least 2 principle reasopns why the clinker from …

The vertical design allows engineers to place the turbines closer together. Groups of them don't have to be spaced far apart, so a wind farm does not have to take up as much ground area. The proximity of horizontal wind turbines to one another can create turbulence and reductions in wind speed that affects the output of neighboring units.

Therefore, we should pay more attention to the formation and shedding of kiln skin in the sintering zone, so as to prevent the bad effect caused by carelessness. Moreover, the coal circle should not be too thick. If we find it is difficult for clinker to pass through, we should clean up in time otherwise it will affect the production.
