Description of the Szego Mill The Szego Mill is a planetary ring-roller mill shown schematically in Fig. 1. It consists principally of a stationary, cylindrical grinding surface inside which a number of helically grooved rollers rotate, being flexibly suspended between flanges connected to a central drive shaft.

A Szego mill is a continuous, wet mill currently used at commercial scale. The Szego mill, developed by researchers at the University of Toronto, Ontario, Canada, is a planetary ring-roller mill shown in Fig. 1 (Trass and Gandolfi, 1990). It consists of a stationary, cylindrical grinding surface known as a stator.

While the Szego Mill is a compact and efficient grinder for many applications, a special niche is wet grinding at high solids loadings. A toothpaste-like consistency appears to give the best grinding efficiency. Size reduction from 6 mm to below 10 microns can be achieved. Grinding can be combined in one step with high energy mixing, leaching ...

Compared with grinding with the Szego mill alone, the combined Szego mill-hydrocyclone unit produced a more uniform finely ground meal. The glucosinolate content of the meal was decreased to less than 1.8 μM/g dry meal, and the polyphenol content was reduced by as much as 88%. The polar filtrate (obtained from the ground …
