  • Coal comminution and sizing - ScienceDirect

    2013-1-1 · The lump coal is convenient for shipping, and is typically ground further at the point where the coal is combusted. Sizing of lump coal is carried out by sieving, which is the most effective sizing process at coarse sizes. In the case of rotary breakers, the breaker itself is a rotating sieve that provides positive control of the coal topsize.

    Comminution is used to reduce the particle size of biomass and increase accessible surface area, reducing crystallinity and degree of polymerization (DP), thus increasing the biomass biodegradability [4]. Typical mechanical comminution includes chipping and milling as shown in Table 2.1. Chipping is usually necessary to reduce the size of raw lignocellulosic biomass for further processing, for example, to …
