Let''s be clear about this: Most coal mill system designs are 30 or so years old, when realised. ... Unfortunately, as indicated, almost no coal grinding system is really good, in this respect. This is the 1st page of a report with 64 pages and 119 illustrations, which isn''t an uncommon volume. ...
The situation is further complicated by the ''mill reject'' streams that reject undesirable material (tramp metal and noncoal bearing rock) from the mill. Generally, the following steps illustrate the path through a VSM: • The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; •

The models are regulated on the basis of available data from grinding mills of the Greek lignite power stations. The numerical code is capable of predicting the locations of significant erosion and to estimate the amount of particle mass that circulates through the mill via the classifying chamber.
within the mill body, coal drying, transport, classification and grinding. For coal pulverizers the capacity of a mill is normally specified as tonnes output when grinding coal with a HGI of 50, with a particle size of 70 less than 75 micron and 1 greater than 300 micron and with a moisture in coal of less than 10.
Analysis of experimental data on aerodynamic resistance of a balltube mill is given. It is shown that this resistance has two components brought about by the pressure losses resulting from the injection of dust particles into the main flow after coal grinding and from the .
With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to % or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of .
