The invention belongs to the field of natural rubber processing and particularly relates to a rubber-fragmentation-resistant natural scrap rubber processing process and device. The method comprises the following steps that a, scrap rubber is cut into small blocks; b, the cut scrap rubber is fed into a water pool with the water temperature being 50-60 DEG C to be soaked, salvaged until the temperature of the scrap rubber is increased to 39-45 DEG C and fed into a washing machine to be washed; c, washed scrap rubber is fed into the water pool with the water temperature being 50-60 DEG C to be soaked again, salvaged until the temperature of the scrap rubber is increased to 39-45 DEG C and fed into a creper to be creped; and d, the creped scrap rubber is pelleted and dried. Due to the fact that the scrap rubber is soaked in the hot water soaking environment before washing and creping, the original physical performance of the scrap rubber is restored to a certain degree, rubber blocks can be prevented from being fragmented in the steps of scrap rubber washing and creping, the cohesiveness of the rubber blocks is remarkably improved, effective processing and production are ensured, and the quality of processed products is improved.
