— However application of the DEM to the impact crushers was rare in the literature Over years the Julius Kruttschnitt Mineral Research Centre JKMRC has successfully modelled two types of impact crushers the vertical shaft impact crusher Napier Munn et al 1996 and the horizontal shaft swing hammer mill Shi 2002; Shi et
The cone crusher is a modified gyratory crusher and accordingly many of the same terms including gape set and throw apply The essential difference is that the shorter spindle of the cone crusher is not suspended as in the gyratory but is supported in a curved universal bearing below the gyratory head or cone Figure Major suppliers of cone crushers
