Abstract

1468649 Disc mills YHTYNEET PAPERITEHTAAT OY JYLHAVAARA 5 Dec 1975 [9 Sept 1975] 50070/75 Heading B2A A disc mill having a stator disc secured with three pins at least one of which is heatable, to adjust the discs for parallelism, includes means to sense axial force between the discs and adjust the length of the heatable pin to maintain parallelism. To do this a strain gauge 11 is secured on the main shaft 9 responsive to length changes in the shaft which in turn are due to the axial force. Continuous control may be exercised, the system may be applied to a double or multiple disc refiner, and a pressure transducer may be used in place of a strain gauge.
