AUTOMATIC OPERATIONAL CONTROL METHOD FOR SWINGABLE TYPE CRUSHING APPARATUS

摘要

An automatic operational control method for a swingable type crushing apparatus which adjusts a crushing clearance by increasing or decreasing it stepwisely by a hydraulic mechanism depending on crushing conditions of the massive furnace slag such as blast furnace slag, convertor slag and electric furnace slag or the like which generate in the processes of iron manufacture an steel manufacture and so forth, wherein a hydraulic pressure of a hydraulic mechanism is detected as variables of the crushing conditions and the hydraulic pressure is compared with set values for adjusting the crushing clearance.
