Apr 15, 2004· Prior to compounding, air‐dried sawdust was ground to evaluate the grinding effect in the mill. As the feed rate and the mill speed increased, the particle size increased and decreased, respectively. Sawdust particles were successfully compounded in linear low‐density polyethylene using the Szego mill without any major heat application.


Size reduction is an unavoidable operation for preparing biomass for biofuels and bioproduct conversion. Yet, there is considerable uncertainty in power input requirement and the uniformity of ground biomass. Considerable gains are possible if the

This successful trial with the compression-type Szego Mill refining was expounded upon and evaluated in a multistage deacetylation pretreated corn stover with high solids Szego milling (Chen et al. 2015b). Combining the Szego Mill compression refining (128 kWh/t disk refiner, 68 kWh/t 10% Szego pass 1, 85 kWh/t 10% Szego pass 2; 281 kWh/t total ...


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 ...
