An improved process and equipment for seed defiberization, for example cottonseed delinting, wherein the seed is defiberized by contact with particular abrasive surfaces. In one preferred embodiment, a conventional cotton-seed delinter is equipped with an abrasive faced cylinder instead of the conventional shaft mounted ginning saws. The abrasive cylinder comprises a shaft mounted cylinder of approximate gin saw diameter which cylinder has bonded or adhered to its facial surface an open pattern of about 40 to about 80 abrasive grit particles per square inch. The abrasive grit particles, preferably tungsten carbide grit, are sized to U.S. Sieve Series numbers of about 12 to about 40. Replacement of the ginning saws with the abrasive face cylinder requires modification to the delinter gratefall rake and seed seals to adapt their shape and clearance to the comparatively flat abrasive cylinder face. The abrasive cylinder embodiment provides means for convenient adaptation of conventional gin saw delinters to achieve increased cottonseed handling capacity, less power requirement and decreased, safer labor requirement benefits.
