By installing a combined roller press and ball mill grinding system in a 2400tpd cement production line, Tianjin Zhenxing Cement Co, Ltd. reduced specific energy consumption by 7.0 kWh/t-cement. For an annual production of 900 000 tons, this provides a saving of around 6.3 TWh/y (MIIT, 2012. p.25).
Furno Materials is working to re-envision the way we make cement. Unlike the large, fixed, capital-intensive plants of today, Furno is leveraging oxyfuel combustion and a novel design to develop plants that are more adaptable and energy-efficient, less capital-intensive and enable the production of zero-emission ordinary portland cement.
The Energy Use Plant Ranking (bar chart) helps cement plants compare their own energy use to that of other plants in the industry. Along the X axis, the chart ranks individual plants from the most efficient (1) to the least efficient (15) in terms of the number of gigajoules used per tonnes of clinker (GJ/T), ranging in single digit increments ...
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.

FCB has just developed a new mill, HOROMILL ®, for grinding cement, raw meal and mineralsThis new grinding process is designed for finish grinding and also for pregrinding The energy saving is similar to the roll press, roughly 30% to 50% better than the ball mill, but with …
In cement grinding, the principle of separate fine grinding will be used. This can be, for example, a vertical roller mill, a high-pressure grinding roll mill or a Horomill, which all produce medium fine products very energy efficiently. The ultra-fine intermediate products will be produced in a fine grinding unit such as a dry stirred. Get Price
