Given the huge range of configurations and operating conditions used in cone crushers, this is a serious issue. Whiten (1972) developed a process model using multiple spline regression which described the effect of crusher geometry with a few parameters. Briggs (1997) developed a simple mathematical model for analysis of crusher geometry.

The most common crushers in crushing sites and industries are gyratory, jaw, roll, and cone crushers . The crushing force in jaw crushers is applied through the elliptical motion of the moving jaw, which crushes the particles against a fixed jaw plate . The charge material is fed into the crusher through the gape at the top of the crusher.

Impact crushers reduce mineral materials such as concrete, asphalt and natural rock in size to produce a valuable commodity product. A fast spinning rotor throws the material against a solid stationary impact wall. The striking and impacting causes the material to shatter into smaller pieces. The result is a very homogenous and cubical product ...

Methods for computational geometry analysis of a cone crusher shape are proposed. • These measures assist in understanding cone crusher geometry, flows and breakage. • They provide insight into the effect of variation in cone height and eccentric angle. • Throughput is related to changes in cross-sectional area and the choke point. •
Abstract. Wear in rock crushers causes great costs in the mining and aggregates industry. Change of the geometry of the crusher liners is a major reason for these costs. Being able to predict the geometry of a worn crusher will help designing the crusher liners for improved performance. A model for prediction of sliding wear was …
