Abstract

1365204 Disc mills YHTYNEET PAPERITEHTAAT OY JYLHAVAARA 4 Aug 1972 [27 Aug 1971] 36454/72 Heading B2A. A disc mill includes a fixed disc 1, Fig. 1, secured to the mill body 13, Fig. 3, by three pins which provide for parallel adjustment relative to a rotatable disc 2. At least one of the pins 4 is heated independently of heat due to operation of the mill, to vary its length and maintain parallelism. As described the pin 4 is hollow and includes a heater element 24, Fig. 5. The discs 1, 2 include blades 9 which constitute the refining surfaces 10, 11. Heating of the pin may be effected alternatively by heating a liquid gas in the cavity in the pin, or by an induction coil therein, by conducting a fluid (which may be a coolant instead of a hot fluid) into the pin, or by vibrating the pin, e.g. ultrasonically. Parallelism, or alternatively stock quality, may be sensed and the heating of the pin may be automatically controlled.
