Abstract
Slag crusher having a shaft extending through a pressure housing which shaft is provided with inlet baffle plates in a funnel-shaped arrangement, stationary cutting knives and cutting knives rotating on the shaft. The shaft is offset with respect to the vertical center line of the pressure housing, so that the crushing area is concentrated in the middle of the slag crusher. The rotating cutting knives are angularly offset on the periphery of the shaft, so that only one rotating knife and two stationary knives are in engagement at a time.
