A Szego Mill was used to wet grind Minto (New Brunswick) coal which was then subjected to laboratory agglomeration by the NRC procedure. A comparison with coal ground in a ball mill indicated superior ash rejection. The improved performance is attributed to better mineral liberation which is enhanced by the more flaky particles produced in the ...Web

Grinding with the cutting mill provided most of the particles with size 1–2 mm whereas with the Szego Mill TM size fractions 0.5–1 mm and 0.25–0.5 mm were dominant . The Szego Mill TM was more efficient for particle size reduction than the cutting mill, which can be seen also from Figure 4 where SEM pictures of biomass milled in different ...Web

Fine grinding mills can be categorized into five groups [48]: impact mills, ball media mills, air jet mills, roller mills, and those of some other type, including disc mills. Impact mills and air jet mills are based on single impacts, as presented in Fig. 4 a, while ball media mills utilize double impacts between metal surfaces ( Fig. 4 b).Web

The processing of fine coal is always more challenging and costly as compared to cleaning of coarse coal. The reduction in size of coal particles during grinding enhances the liberation of mineral matter and also improves the process of agglomeration (Garcia et al. 1995). Nevertheless, there is a fine line between sufficient grinding and …Web

Experiments with the Szego mill, which is able to handle the pasty agglomerates, have shown that ash removal from Minto (New Brunswick) coal is comparable to that obtained with the usual NRC process. The generally flaky products of the Szego mill allow better ash liberation, and the presence of oil enhances grinding performance.Web
