摘要： A crusher for crushing cooked wood chips or the like finely. A raw material to be crushed such as the cooked wood chips is delivered into a housing and clamped between stationary blades attached to a stationary plate housed in the upper end of the housing and rotary blades attached to a rotary plate rotating in the housing, so that it is finely crushed by the stationary blades and the rotary blades by making use of the planer principle. The crushed products are carried in the air flow, which is generated around a guide vane disc, which rotates in a through hole formed in a substantially central portion of the stationary plate, and forcibly delivered from an exit in the housing side wall front portion inclined forward, to the outside of the housing.
