In this article, a delivery pipe for pulverized coal fines from a coal mill to a combustion chamber, a device for diffusing unevenly distributed coal flow evenly across the pipe is described.Abstract:
In a delivery pipe for pulverized coal fines from a coal mill to a combustion chamber, a device for diffusing unevenly distributed coal flow evenly across the pipe. In a first form, the invention comprises a plurality of static, lateral, linear diffuser elements comprising rows of protrusions or teeth spaced laterally across the coal flow path in the pipe, preferably in a staggered and overlapping relationship. In a second form, the diffuser elements are rotatably mounted across the coal flow path in the pipe, and may be rotated at different speeds and in different directions. The diffuser elements spaced across the coal flow path in the pipe may be supplemented by peripherally-mounted diffuser elements at the inlet of that portion of the pipe or housing to provide an angled pre-diffusion of the coal flow from the sides of the pipe toward the lateral elements extending across the interior of the pipe.read more

Impact-attrition mill utilizing air flow
TL;DR: In this article, an impact rotor was used to obtain the initial reduction of large ore chunks and particles by impaction against hammer bars mounted on the rotor and shatter bars, and a secondary reduction was obtained when the heavy particles are carried by the air flow into contact with breaker bars in a fine reduction chamber.
