The poor grindability of untreated biomass [21,22] impedes the throughput of coal pulverisers. For example, when milling wood chips in an industrial vertical roller mill, the maximum capacity mass throughput is 0.25 t h −1 while that of coal is 2.2 t h −1 . This is a mass-flow difference of almost nine times.

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
