The feed material is continuously fed to the crusher. Large material blocks are first precrushed between the rotos. Subsequent reduction takes place on the anvil before the finished product is produced on the discharge grate. This mode of operation without fixed impact walls also permits the handling of comparatively moist and sticky material.
