The Raymond Bowl Mill is considered the finest vertical roller mill available for pulverizing coal. The typical Raymond bowl mill system is designed to simultaneously dry, pulverize, and classify solid fuels to 95% passing 200 mesh (<5%R75μ) with a wide range of capacities from 24 to 150 stph.

the pulverizer in adjusting the coal flow distribution." Elshabasy continues, "The laboratory tests were carried out in the Center's Coal Flow Laboratory, using a scale model of a pressurized vertical spindle mill. I modified the mill internals by adding flow control elements at strategic locations. These flow control elements were

 — Associated minerals in the raw coal increase the energy consumption and abrasion of grinding media of vertical spindle pulverizer (VSP). Moreover, the low separating efficiency of classifier in VSP leads to the return of fines to grinding table, worsens the grinding phenomenon and make the energy-size reduction of coal complex.

 — A one-third scale model of a vertical spindle coal mill static classifier was used in the present experiments, see Fig. 2. The geometry of this particular classifier design is based upon the 10E10 Mitsui Babcock mills used at AES Drax power station in Yorkshire.

Bilirgen explains, "Pressurized vertical spindle mills have anywhere from 2 to 10 coal pipes connected to the top of the pulverizer discharge turret. Imbalances in pipe-to-pipe coal flow rates may arise due to nonuniformities in the coal and air flow patterns within the pulverizer. With research funding from the Babcock &

optimization project was to first achieve optimum mill performance. Therefore, the purpose of this paper is to help further review this proven approach to vertical spindle mill optimization. First of all, let's discuss why "great" coal fineness is better than the typical industry accepted "good" coal fineness. The following figure ...
