The objective of this study was to investigate the breakage characteristics of LRC by swing hammer mills for use in clean coal technology. Generally, the appropriate range of particle size distribution for the brown coal upgrading process is 100–3,000 μm, and thus, the process considered in this work is designed for this range. To design the ...

Hammer mill is one of the machines used in size reduction. Hammer mills reduce particle size by breaking due to the impact of the hammers, shearing by the edge of the hammers and screen, and collision among the product and in between the product and machine. The impact is the primary force to reduce particle size in a hammer mill.
