The Breakage of Shape-Anisotropic Particles under Normal Contact with Different Particle Shape Parameters

This paper elaborates the cone–hemispherical gypsum particle breakages under normal contact with different shape parameters (contact diameter d, cone angle θ and sphere D) proposes a simple quantitative approach to discriminate breakage modes. The effects of on are investigated through analyzing processes, modes force–displacement curves. Three formed during experiments: peeling, peeling–splitting splitting, corresponding three formation conical core is deemed as precondition for splitting. mode transfers from peeling splitting increase in d θ, but decrease D. critical force Fcr positively linearly related relationship between D heavily depends mode. Furthermore, dcr described by proposed particles.
