Abstract
A control method for crushing massive furnace slag using a swingable type crushing apparatus in which a crushing clearance is increased or decreased in a stepwise manner by a hydraulic mechanism depending on crushing conditions of the massive furnace slag, which may be blast furnace slag, convertor slag, and electric furnace slag. A hydraulic pressure of a hydraulic mechanism is detected as a variable of the crushing conditions and is compared with a set value so as to adjust the crushing clearance.
