Abstract
A chip crusher composed of a rotating disc and at least one crushing roller mounted to form a nip with a working face of the disc adjacent the periphery of the disc. The chips pass through an inlet and engage the rotating disc which flings them towards the periphery of the disc thereby to spread chips into a substantially single thickness layer. Each chip moves with the disc into the nip between the roller and disc wherein the chip is crushed. The crusher fissures the chip to a degree substantially proportional to the original chip thickness and thereby produces crushed chips having more uniform pulping qualities than regular chips.
