Dynamics in double roll crushers

Rolls were easy to manufacture, to install and to operate in a wide range of applications. A robust and reliable design, low machine height and an excellent ratio of capacity versus machine mass make double-roll crushers (DRC) still today the preferred choice for many soft to medium-hard rock applications in quarries and ore mines.

New insights into double roll crushing

In coarse comminution, double roll crushers (DRC) are used for the size reduction of blasted materials and in secondary comminution. In the primary crushing stage, DRC with toothed rolls are of particular importance. In contrast to smooth rolls, these offer improved nip conditions so that larger particles can be nipped, and crushed.
