Grinding apparatus especially for lignocellulose containing material

Abstract

Abstract A grinding aparatus especially for lignocellulose containing material having two pairs of cooperating grinding discs. In each pair of grinding discs one disc is fixed to a stationary casing and the other carried on a common shaft extending through the casing from end to end and mounted rotatably in bearings permitting axial self-adjustment of the shaft responsive to the pressure prevailing in the interspaces between each pair of cooperating grinding discs; the disc mounted on the rotatable shaft performing a rotational movement relative to the disc which is fixed to the stationary casing. Each pair of cooperating grinding discs has a supply channel for the material to be ground. A feeler member is provided to ascertain the axial position of the shaft and adapted to emit an impulse to a control or regulation member for distributing of the material to be ground to the supply channels in such a manner that divergences in the width of the interspaces within the two pairs of cooperating discs are compensated by increase of the supply of material to be ground to the channel communicating with the interspace having momentarily the smaller width.
