The CEP is based on the self-inert coal grinding and drying process by Loesche. This process is well established for coal preparation in cement plants and iron works for pulverised coal injection Figure 1. However the main difference between this established process and the new CEP is that a fraction of the
grinding the dried material to the desired particle size. This chapter deals in some detail with the most generally practised method of large-scale production. A more cursory description is given of small-scale processing and plants designed to handle small and irregular landings of fish or to yield products with special properties.

Oct 21 2011 In the case of coal-grinding or storage as one might find in a cement plant it is not possible to remove the fuel coal or ignition source grinding energy heat static charges and so one has to concentrate on removing the third necessary component - O 2. This fact has given rise to inerting systems that rely on the use of inert gases.
