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.

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.
Simulation. This section presents a dynamic simulation example of the LT300GPB tertiary mobile cone crushing plant. The simulated plant layout is given in Fig. 5. The plant consists of a GP300 tertiary cone crusher (medium chamber, 32-mm stroke length, 330-rpm ES and 16-mm CSS), a B2100T two-deck screen …
Every jaw crusher diagram is a window to the soul of this rugged machine, providing vital insights to the components that make up its robust design. At the heart lies two pivotal plates: the fixed jaw and the movable jaw. The fixed jaw, as the name suggests, remains stationary and serves as the backbone for the crushing process.
