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.

The Szego Mill™ is a planetary ring-roller mill consisting of a stationary, cylindrical grinding surface inside which a number of helically grooved rollers rotate. The biomass is fed by gravity or pumped into the mill from top, and then discharged at the bottom of the mill.
Abstract Performance data for the wet grinding of coal have been obtained in this novel, planetary ring-roller mill over a wide range of operating conditions. Results from mills of different sizes are presented, with rotational speed, feed rate, coal loading in oil and water, type of coal and residence time in the mill as the main variables. Combining empirical results with insight …

The simultaneous grinding/agglormeration process has been used to beneficiate Minto coal. Experiments with the Szego Mill, a planetary ring-roller mill with grooved rollers, have given good results. Different roller ridge/groove sizes have been tested and favourable oil-coal-water ratios established. Ash removal is closely related to grinding performance.
The Szego Grinding Mill. The Szego Grinding Mill. The szego mill is the worlds most cost-effective and maintainable modular grinderefined and proven over 40 years, it has a unique ability to produce ultra-fine particulates smaller and more efficiently than other mills while using less power and taking less space.
Wet grinding of coal in the Szego Mill (Conference) @article{osti_45146, title = {Wet grinding of coal in the Szego Mill}, author = {Gandolfi, E A.J. and Leszczyniecki, R and Trass, O}, abstractNote = {New results from a systematic grinding study with the larger, SM 320 Szego Mill are reported.
Abstract. 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.
The Szego Mill is a planetary ring-roller mill with radially mobile, helically grooved rollers. It has a high capacity for its size and is suitable for continuous dry or wet grinding, including pastes with high solids concentration. It reduces size rapidly, and with a relatively low power consumption. In this paper, results for mica grinding ...
Nano Grinding Mills: Tiny Particles Can Be a Big Deal. Nanonization refers to the creation or manipulation of particles ranging in size from 1 nanometer (nm) to 100 nm. Much of biology happens at nanoscale. Nanoparticles can be fabricated using bottom-up or top-down methods. Bottom-up nanofabrication refers to building particles using chemistry ...

The Szego Mill is a patented industrial grinding mill with huge ROI benefits to Cleantech, backed by 40 years of R&D and more than 100 research papers. It doubles biogas output, creates clean fuel...
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 ways have been …
Results from an investigation of the mechanical size reduction with the Szego Mill™ as a pretreatment method for lignocellulosic biomass are presented. Pretreatment is a highly expensive and energy-consuming step in lignocellulosic biomass processing. Therefore, it is vital to study and optimize different pretreatment methods to find a most efficient production process.

The Szego Grinding Mill. A dynamic wet-grinding model recently developed for the szego mill is reviewed. use of this model allows a priori predictions of limiting performance for all design and operating variables in the "paste grinding" regime, i.e., at relatively high solids concentrations which are optimal for wet grinding in the szego mill. limiting size predictions for the sm-320 …
