The utility model discloses a screened material return grinding device which comprises a pulverizer, a salt cooler and a fan. The pulverizer comprises a granule inlet, a granule outlet and a material return port. The material return port of the pulverizer is connected with the salt cooler. The granule outlet of the pulverizer is connected with a screening machine through a gas-solid separator. The gas-solid separator is connected with the screening machine through a star-shaped charging valve. The gas-solid separator is connected with the fan through a filter. The fan is connected with the salt cooler. The screening machine comprises a finished material outlet and a rough material discharge outlet. The rough material discharge outlet is connected with the material return port of the pulverizer. The screened material return grinding device greatly improves production capacity of the pulverizer and product quality, enhances stability and reliability of a styrene ethylene butylenes styrene (SEBS) postprocessing pulverizing system, is suitable of powders of SEBS, and optimizes systematic process of the pulverizer.
