Coal Mills in 1924

With the installation of rotary kilns from 1900 onwards, plants needed coal mills to produce the kiln fuel. This ocurred at a time when grinding equipment was still in rapid development. The first generation of coal mills therefore became rapidly obsolete, and later rotary kiln installations had better firing systems. The 1924 plant schedules for APCM and BPCM provide a snapshot of the early installations that were mostly on the point of replacement with newer equipment. There also exists fairly reliable information for most of the other companies in the industry for 1924.

A feature of the firing systems of the time is that they are almost entirely indirect in design. A few direct-firing high-speed mills had been installed in the early 1920s, but major expansion of direct-firing systems only began in the second half of the decade.

In the table, mills marked with an asterisk (*) are de-commissioned. The "duty" column shows the capacity throughput of the system in dry standard tonnes per day.
