Abstract
A single-roll crusher has a crushing roll formed with a plurality of hammers and disposed above an anvil or breaker plate which can form the bottom of a trough through which a conveyor passes to carry the material to be crushed into the breaker and the crushed product therefrom. The height of the central portion of the roll above the anvil plate defines the maximum size of the material which can be comminuted. To stabilize the rotation of the roll and yet permit this distance to be relatively great, a pair of massive circular spinning disks are mounted on the roll shaft coaxial with the roll. The disks flank the channel through which the material passes.
