How do agglomerates break? | Request PDF
As a consequence, DEM simulations have been widely used to investigate the breakage of agglomerates, particularly in identifying broken interparticle contacts induced by impact (Kafui and Thornton ...
The Crushing Distribution Morphology of a Single Particle …
In a vertical shaft impact crusher, the particle crushing process is extraordinarily complex, and the particle shape significantly influences the size distribution of the crushed product. To quantify the crushing behavior of particles more accurately and thus reveal the crushing mechanism of the crusher, an analytical approach is suggested for characterizing …

Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less.
Prediction of attrition in agitated particle beds
Neil and Bridgwater (1994) and Ghadiri et al. (2000) found that the relative influence of strain and stress is better described by (7) W = k N ⋅ [(σ σ S C S) ⋅ Γ φ] β where σ SCS is the side-crushing strength of the material, k N is the proportionality constant, β is the power index and φ expresses the relative influence of strain ...
