The main difference to cement mill operation is the need to dry raw·feed and assure transport of stightly moist materialwithin a mill. Also, many raw materials are softer than clinker, and operations must avoid coarse residues in kiln feed that are difficult to combine in the kiln and would result in high clinkerfree-lime, and/or excessive ...

After crushing, the raw materials are transported to the plant by conveyor. Before homogenized, the plant stores the material. Too finely ground, the materials are transferred to the raw mill, to produce raw mix. The raw mix is preheated before it goes into the kiln, and by the flame, it can be heated to 2000 °c to produce clinker.

New technologies can be developed to reduce its energy consumption as sizeable energy is consumed in grinding operation of a cement manufacturing process. In another study [16], it was found that cement mill, raw mill, crusher and heater consume approximately 38%, 35%, 3% and 24% of total energy, respectively. Download : …

Raw coal is fed into feeding device of coal mill in cement plant, the hot air with temperature about 300 ℃ through the duct into the feeding device, there is a special lifting board in drying storehouse board will raise the raw coal, and helps the raw coal exchange heat and be dried, dried coal enter into the grinding storehouse.

The vertical mill's drying capacity is strong, and the waste heat of the kiln can be used to dry the raw materials with a moisture content of 8% or higher. The air ring area, the air ring angle, and the dam ring's height can be adjusted according to the working conditions. Detection devices are equipped for mechanical, electrical limit and ...
