The mill, however, could only be used where the current flow was suitable for grinding. The geared vertical-wheel mill was more versatile. Construction was relatively simple if the wheel was of the undershot kind, because the wheel paddles could be simply dipped in the stream flow, whether it was river, tide, or man-built millrace.

The process capability of a fluidized bed hammer mill was investigated with respect to four process variables, namely, rotational speeds of beater system and classifier wheel, airflow rates and length of grinding zones, as well as the particle size and flow property of the starting materials.

The beater wheel mills built by ALSTOM Power Stuttgart are designed for maximum productivity. In nearly all major atmospheric, -lignite-fired steam power plants, the crude lignite is dried and pulverised in ALSTOM beater wheel mills. The beater wheel mill sucks hot flue gases from the cumbustion chamber through the flue gas pipe to dry the coal ...

A Hollander beater design consists of a circular or ovoid water raceway with a beater wheel at a single point along the raceway. The beater wheel is a centrifugal compressor or radial impeller cylinder parallel to a grooved plate, similar to the construction of a water wheel or timing pulley. Under power, the blades rotate to beat the fiber into a usable pulp slurry.
