The present invention has the function of breaking coconuts, nuts, tnacadamia nuts, an similar by increasing compression using wedge and rolling compression, having pins and fins on the roll surface, it favors less energy consume, more yield, and productivity qualitative gain of the whole macadamia nut (with higher aggregated value) and quantitative utilization of broken coconuts, nuts, macadamia nuts, and similar of 100%, continuous work, installation, maintenance and training costs extremely low, and consequently low final cost of the finished product. The said equipment is constituted of a roll (3) that rotates having on it, conveniently spaced, a cylinder segment (4), being the space existent between them in a wedge shape in such a way that once penetrating in this section, a coconut, nut or similar (10) is compelled to dislocate inside it, rotating and being continuously compressed until the shell rupture, without suffering shock.
