AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training
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 °.

Forces in a Cone Crusher | SpringerLink
Abstract The literature on the design of cone crushers and analysis of the corresponding crushing processes is mainly based on empirical observations. As a result, it is generally accepted that the crushing action is due solely to compressive forces. Crushers are designed on that basis. Accordingly, many cone crushers today are characterized by …
