FIELD: textile, cotton.
SUBSTANCE: intended to be used in pulp and paper industry. Offers the plate-shaped elements, the construction of plates and related thereto the installation for the thermal mechanic refining of the arboreal refuse wood where the grinded and partly grained refuse wood is delivered to the first refiner with rolling discs where each of the opposite discs has the knife and groove tracery of the internal wheel and knife and groove tracery of the peripheral wheel. Essentially, the refuse wood reaches its full grained condition within internal wheel and the grain is fibrillated within peripheral wheel. One version of the realisation are two opposite interacting refining element as the plates for refiner with flat discs where the knives and grooves of each of the internal wheels form the internal area of delivery whereafter there is a peripheral operation area. Knives and grooves of each of the peripheral wheels form the internal area of delivery whereafter there is a peripheral operation area, and the gap and/or space for the material flow passage formed during the installation of the plates one after another increases between internal operation area and peripheral operation area.
EFFECT: provides high-quality thermal mechanic arboreal mass at the low energy consumption.
