    Cone Crusher - an overview | ScienceDirect Topics

    Cone crushers were originally designed and developed by Symons around 1920 and therefore are often described as Symons cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory

    Jul 21, 2020 A horncore feature was encountered during excavations at Border Cave, in Member 2 BSL, dated 60–49 ka. The basal half of the horncore lay towards the centre of a combustion feature and was calcined. The tip half lay on a mat of burnt grass bedding towards the edge of the fireplace. It was covered with a black shiny residue, which was also present on

    In the present study, mixed maghemite-magnetite nanoparticles have been used as adsorbents for Cr(VI), As and Cd(II) removal. From the study, it is apparent that the removal of Cr(VI ), Cd(II) and As(V) by mixed iron oxide nanoparticles depends on pH, temperature, contact time, solid/liquid ratio and initial concentration of heavy metals
