Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.

bins to the raw mill. An extremely important step in the cement process is to proportionally feed these materials to the raw mill to ensure the correct "blend" of these materials. The raw materials, now known as kiln feed, enter a raw mill that consists of a drying chamber and a grinding chamber.

The mills for grinding the raw materials are 2.4m in diameter and 11.0m long and are driven by 720kw (1000HP) electric motors producing 45t/h of slurry. The cement is ground in two mills: one 2.4m x 11.0m long producing 18t/h of cement; the other 3.8m x 11.4m, powered by 2300kw (3000 HP) electric motor and producing 60 t/h of cement.

dust-fired large-scale power plant in Berlin for coal grinding with a raw coal rate of approx. 12 t/h. 1934 Loesche mills are increasingly also used worldwide for limestone and cement raw material. 1937 400 Loesche mills have already been sold for coal, phosphate and cement raw material. 1939 The largest Loesche mill at this time is an LM 16

The study indicates that for a dry type cement production process, the carbon dioxide emission intensity for kiln feed preparation process is about 5.4 kg CO 2 per ton cement produced. In this study, the raw mill of a cement plant is considered and its performance based on the first and second laws of thermodynamics is investigated.

We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
