Forces in a Cone Crusher SpringerLink

Mar 21, 2019 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 common operating principles.
