Abstract
A pulverizing mill for particulate material such as coal, containing a plurality of roller units each pivotably attached to the mill casing. The roller units are each biased downwardly against a rotatable table and annular track by dual loading arms which are pressed downwardly by spring means located outside the casing. The spring means are provided either by coil type springs contacting the loading arms, or are provided by the loading arms being fixed at their outer ends to the casing so as to act as curved torsional spring arms to provide a downwardly force on the roller units. The roller unit pivot shaft is advantageously attached to the casing at a level below the roller axis.
