Improvements in the refining for preparing pulp characterized by having two cutting plates arranged opposite each other, one of them being fixed and the other rotating and both having a series of front teeth of different lengths of each other interspersed with each other and having a shape such that the distance between the two plates decreases towards the periphery, achieving thanks to the described design a progressive cut and a lower power consumption.
