<p>A crushing roll blade secured to the circumferential surface of a roll and used to crush or grind hard industrial waste and agricultural and marine products, in which a prismatic body is disposed so that one acute angle part of the prismatic body faces in the rotational direction, grooves being formed in the prismatic body so as to extend from a front part thereof to a rear part thereof with respect to the rotational direction and in parallel with the left and right ridgelines of the upper surface of the prismatic body, whereby the blade consisting of front end edges, front edges and cutting edges is formed. The formation of the grooves, which will weaken the construction of the blade, is limited to the front part of the prismatic body to improve the strengh of the blade, while increasing the depth of the grooves to obtain crushed particles of a desired diameter.</p> |
