Usually, the grinding process in the cement industry (and in the steel and other industries) is combined with coal drying. Hot, exhaust air low in O 2content from the kiln process and/or its preheating stage, along with air from other sources, enters the mill in order to contribute to the drying process with its thermal energy and to dilute the O
The mobile coal grinding plant can process different types of coal under almost all environmental and physical conditions and make it available to a downstream thermal process. Loesche is certi˜ ed according to EN ISO 9001, our grinding plants meet all national and international safety requirements.
Prior to the coal grinding plant a raw coal pre- drying plant will be installed. In a first step the pre-crushed coal (< 25 mm) will be pre-dried using higher temperatures than allowed for pulverized coal at a reasonable airflow and a low pressure drop. In a second step the coal will be ground to the requested fineness and further dried, if ...
The coal was crushed in the Coke Department of Cze-stochowa Plant. The numerical determination of grain size distribution of crushed coal was made, and the re-sults obtained in this way were compared with the re-sults of laboratory analyzes of grain made. In this pur-pose, the results of the grinding process in a hammer crusher (Figure 1).
The layout of your coal grinding system must take into account the available heat sources for drying the raw coal as well as the fire and explosion hazards of coal and coal dust. The entire grinding plant must therefore be shock-resistant and equipped with a number of explo-sion relief valves. From the raw coal silo, the feed is
