Abstract

The invention relates to a pulping machine millstone. The pulping machine millstone is installed on the rotor or the stator of a pulping machine, and a disc surface grinding edge angle formed by at least part of grinding edges of the millstone and the rotation direction of the rotor of the pulping machine is in an angle range of 105-150 degrees. The invention also relates to the rotor comprising the pulping machine millstone, a pulping machine and a double-disc pulping machine.

Description

technical field [0001] The invention relates to a refiner plate, a refiner and a rotor. Furthermore, the invention also relates to any type of refiner. Background technique [0002] Low consistency refining of fiber stock suspensions (chemical pulping / physical pulping / recycled fibers) is a routine practice to improve fiber properties and strength. There are various disc pattern styles on the market, especially for the most commonly used type of double disc refiner. However, there are also conical refiners as well as cylindrical refiners on the market. Regardless of shape, all refiners are equipped with grinding discs with sharpened edges and grooves. Loading (reduction of the gap between the refining discs) is used to provide the required refining energy to achieve specific fiber properties. The fiber suspension, typically with a concentration between 4-5%, is pumped through the refining disc and due to the fact that there is at least one rotor and at least one stator, t...
