There has recently been a resurgence in research into brown coal upgrading by slurrying and/or grinding followed by drying, e.g. Bassler, 1974, Woskoboenko and Stacy, 1985, Woskoboenko et al., 1988 and Johns et al., 1989. However, densification of Victorian brown coal by drying colloidal suspensions was first reported by Thwaites (1927).
The grindability of coal is important for entrained-flow gasifiers, which require pulverized coal for dry feeding systems or coal with a wide range of particle size distribution for slurry feeding systems. Because grinding is an inefficient process, choosing coals that are easier to grind can increase the overall efficiency of the process.
