FIELD: biofuels.
SUBSTANCE: group of inventions relates to the processing of lignocellulose material. The segment of the refiner plate contains a base having radial length, inner and outer diameter, side surfaces, a rear surface. The front surface additionally contains an area having a plurality of alternating grinding knives and grinding grooves, in which the grinding knives contact the base, and adjacent grinding knives and the base form a grinding groove between adjacent grinding knives. The area of alternating grinding knives and grinding grooves is known as the grinding section, which contains the areas forming the feeding grooves. Each feeding groove extends from the area adjacent to the inner diameter of the base in the direction of the outer diameter of the base. Each feeding groove has a first width closer to the inner diameter and a second width closer to the outer diameter, with the first width larger than the second width. The feeding groove is positioned at the feed angle on the first width and at the retention angle on the second width. The material is pumped into the refiner and ground using a segment of the refiner plate with a feed groove.
EFFECT: grinding efficiency increases.
