PROCESS FOR CRUSHING HARD MATERIALS WITH OSCILLATING JAW CRUSHER

摘要

An essential aspect of a process for crushing hard materials which results in a significant reduction in the investment and operating costs per ton produced is the curved, double-acting mobile crushing jaw (3) connected to an oscillating lever (1) which houses the hydraulic compression cylinder (2) or the known articulated lever arrangement which generates the crushing pressure and the unbalance motor (5) which generates the splitting pressure. Another major aspect of the invention is the arrangement of slit-shaped openings (7) arranged at approximately 40° in the fixed jaw (6) of the crusher, which sift the crushed materials ghfjg # dnsndmsn
