  • the cooling of the two-roller mill described is of particular importance, since clogging of the profiling or corrugation can surprisingly be avoided by the cooling in this method.
  • This is of essential importance, because clogging of the profile means that the shearing effect in the gap is reduced and the material breaks into finer pieces. Furthermore, the open, central nip is reduced and this also leads to more fines being produced. After the next pass through the screen, both are returned to the roller press as fine returns and run through the process again. This unwanted fine material increases the circulating load in the plant and thus the output of product is reduced. Overall, clogging of the profiling consequently leads to a reduction in efficiency and thus to a reduction in the cost-effectiveness of the system. According to the invention, these disadvantages are avoided in a surprisingly simple manner by the described cooling of the rolls, specifically in a two-roll mill within the described method.
