Ball mills have been used for the preparation of coaloil and conventional coalwater slurry fuels, also in large sizes up to a capacity of 50 tonnes of coal per hour (Austin et al., 1984). The Szego Mill has not yet been scaled up to large sizes, but its further development includes combining coal beneficiation with the grinding task.

The Szego mill is a planetary ringroller mill which is limited to continuous grinding operations and has a fast rate of material breakage. Hence, breakage parameters, S the selection function and B the cumulative breakage function for Pittsburgh coal, were determined utilizing new experimental techniques.

The shapes of particles produced by comminution in the Szego Mill, a planetary ringroller mill, in different coal grinding operations show that particle shape is dependent on the type of operation, and help explain the breakage mechanisms. Dry grinding produces particles with a low aspect ratio due to interparticle attrition; significant briquetting of fine particles may occur. In slurry ...

Introduction. In a magnetic separation system, the force on a particle toward increasing field intensity (F) is expressed by (Svoboda, 1987) F∝V(S p −S o)H d H d l, where V is the volume of the particle; S p and S o are the magnetic susceptibility of the particle and surrounding media, respectively; H is the magnetic field intensity; and dH/dl is the magnetic field gradient.

This mill is known to give typically flaky particles in wet grinding (Koka and Trass, 1985). Also, regrinding of a proprietary, formulated CWF with the Szego Mill caused slurry rheology to change from dilatant to pseudoplastic. Better homogenization may have helped, or a change in particle shape may have improved particle orientation at high shear.
