About this site

Mar 01, 1990 · 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 ...

Characterization of Szego-milled Hemp Fibers

The Szego Mill used in this study is a planetary ring-roller mill which shown in Figure 2.2. It has a simple structure which consists principally of a stationary, cylindrical grinding surface inside which a number of helically grooved rollers rotate.

分享: The Szego Grinding Mill(grinding mill)

The Szego grinding 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. These radically mobile rollers are suspended from flanges connected to the central drive shaft; they are pushed outward by centrifugal force and roll on the grinding surface.
