TECHNICAL NOTES 5 CRUSHERS

The chief difference between cone and gyratory or jaw crushers is the nearly parallel arrangement of the mantle and the cone at the discharge end in the cone crusher. This is illustrated in Figure 5.2. Reduction ratios in the following ranges are common for cone crushers: 6:1 - 8:1 for secondaries 4:1 - 6:1 for tertiary and quaternary crushing.

Gyradisk Cone Crusher. For finer size products (e.g., -6 mm), a special cone crusher known as the Gyradisc is commonly used. Operation is similar to the Standard Cone Head; however, breakage is mostly by attrition rather than impact. Reduction ratio is around 8:1. Feed size is limited to less than 50 mm with a nip angle between 25 ° and 30 °.
