Binder+Co Double roll crusher. An optimum grain size of 10 to 50 mm is crucial for sensor-based sorting of cullet since a higher content of fines (0-10 mm) would have an unfavourable effect on sorting performance. In the form of the double roll crusher, Binder+Co has created the ideal prerequisite for the subsequent sorting of waste glass.
Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

Roll crushers can be configured with one, two or three pairs of rolls, depending on the application. Compared to hammermills, roll crushers can produce a more uniform grind at a much lower operational cost but cannot attain as fine a grind. Figure 3 shows a sieve analysis for a grind from a hammermill and a roll crusher.
The fixed roll is mounted in self-aligning roller bearings and is secured in the housing lower section. The floating roll is mounted in rocker arms, hydraulically supported against the housing lower section. In order to guarantee parallel retraction of the floating roll, the rocker arms are connected to one another by a torsion axle.
