A crusher, which is simple in the construction and can serve for processing materials easily by, for example, shearing, crushing, blending, homogenizing and transference, with lower energy consumption while suffering scarcely from clogging, even for materials having different physicochemical properties together with different components and composition of the tissues thereof, the said crusher comprising a first pressing element having a first pressing face provided thereon with protrusions each in a form of an isolate island surrounded by depressed marginal spaces, the said protrusions being disposed not only in first parallel rows but also in second parallel rows which extend in a direction crossing the first parallel rows, and a second pressing element to be held in engagement with the first pressing element when being pressed thereonto, the said second pressing element having a second pressing face provided thereon with protrusions which are disposed in a pattern similar to that of the protrusions of the first pressing element, wherein the protrusions of the first and the second pressing elements are disposed in such a relation that the protrusions of the first or the second pressing element will engage with corresponding depresse dmarginal spaces on the second or the first pressing face of the second or the first pressing element, respectively, so as to permit crushing of the material supplied to the interspace therebetween.
