IMPROVING THERMAL AND ELECTRIC ENERGY EFFICIENCY AT CEMENT

2.5.4 High-Pressure Roller Press as a Pre-grinding Step for Ball Mills .. 31 2.5.5 Improved Grinding Cement accounts for at least 5 percent of anthropogenic emissions of greenhouse gases, and, according to some estimates, this share may be even higher. At the same time, energy-related expenses in the cement sector, mostly on fossil fuels and electricity, account for

8 Proven Ways to Stop Machine Tool Chatter on a Lathe or

Chatter is the presence of vibrations that occur when tool pressure is too high, spindle speed is too high, or feed rate is too low. The cause of chatter can be located in either tool setup or work piece setup. Chatter is usually due to too high tool pressure or insufficient rigidity. It does not matter whether the tool is a parting tool, turning tool, or boring tool, every machine tool is

Roller presses, working together with dynamic or static separators, are equipped by a modern automatic pressure control system. In these cases, with the EF device, the pressure and the power of the roller will automatically be returned to the former level. Power consumption and semi-product quality do not change, but the capacity of the roller press increases by at least 10
