6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.

Crushed Stone Processing Major rock types processed by the crushed stone industry include limestone, granite, dolomite, traprock, sandstone, quartz, and quartzite. Minor types include calcareous marl, marble, shell, and slate.
As a result, the forces acting in a double roll crusher could be much higher, at least locally, as one would expect for normal single particle comminution. This should be true even if the DRC is, as usual, starvation fed with just about 15 per cent of the crushing gap filled with solids. 3. Crushing and bearing forces.

Double-Roll-Crushers are used for the crushing or medium-hard rock as well as for sticky and soft materials, i.e. clay, marl, limestone and similar raw materials. Sticky and soft materials are reliably crushed in 2 or 3 stages down to the required product size. Find out more Roll Sizer
The crushing force F Zh and accordingly the horizontal bearing force F Lh are obtained from the equilibrium of moments in the roll center ( Fig. 5) ( Höffl, 1984 ): (9) F Lh = F Zh = M d R W · sin δ with the assumption of δ = α 4 for the angle of resulting crushing force acting on the rolls. For a nip angle α of 33.4° this would lead to δ = 8.3 °.
