Nevertheless, there is a fine line between sufficient grinding and doing it overly. Lin et al. and Chen et al. have shown that with increase in grinding time, the ash content of the agglomerates first decreased and then increased (Lin et al. 2012; Chen et al. 2013). The justification behind decrease in ash content of agglomerates is ...

Flow of dry particulates in the Szego mill

RTD studies in the Szego mill is a more difficult experimental task because of the very short mean residence time in the mill, when compared with that in tumbling mills. While the RTD in the Szego mill has been measured for wet grinding of coal [21, 22], only a few measurements [23] have been reported for dry grinding. This paper is concerned ...

One feature of the Szego mill is that the rollers rotate at 840 Fuel 1997 Volume 76 Number 9 high speed in grinding and cause intense agitation of the slurry, similar to an intense-shear mixing tank. It should therefore be possible to replace the stirred tank in the HFF process by the Szego mill.

Modified oil agglomeration process for coal beneficiation. iv.

Simultaneous grinding and agglomeration (SGA) in the novel Szego Mill allows significant simplifications and energy savings. The excess grinding energy is used for mixing and agglomerate formation. Results are reported over a range of operating conditions.

The Szego Mill excels in simultaneous grinding, beneficiation and production of coal-slurry fuels. A patent was granted for simultaneous grinding and beneficiation of coal with oil and water in the Szego Mill. In the mill, ash is liberated from coal and enters the water phase, and coal is reduced in size and forms agglomerates in the oil phase.

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).

Wet Grinding of Coal in the Szego Mill: Limiting Predictions …

Results from a systematic grinding study with the SM-320 Szego Mill are reported. A wide range of flow rates, from 750 to 5300 kg/h of coal, at 60–65% solids concentration has been covered, with both single and multiple passes through the mill. Particle size distributions and power consumption have been measured.
