Bauer attrition mill

Figure 9.11 Diagram of a Bauer attrition mill. Configuration shown is used for fine milling degerminated residue. With wider spacing of interlocking teeth and no impact ring, it is used for degermination (first-break) milling.

The Andritz-Sprout-Bauer attrition mill (Fig. 20-51) is available in single- and double-runner models with 30- to 91-cm- (12- to 36-in.-) diameter disks and with power ranging up to 750 kW (1000 hp). By the use of a variety of plates and shellconstructions these units are represented in such applications as coarse granulating, pulverizing, and shredding.
