Proppant modification experimental device and application thereof

The invention relates to a proppant modification experimental device which comprises a roller, a power pump driving the roller to rotate and an injection pipeline for injecting an agent into the roller. The device is characterized in that the inner wall of the roller is a smooth continuous curved surface. A roller cover is arranged on one end of the roller and a roller shaft hole for the injection pipeline to extend into the roller is formed in the other end of the roller; the power pump drives the roller to rotate through a belt and the rotating speed of the roller can be specifically set according to basic properties of different materials and agents, thereby achieving the best mixing effect. The device provided by the invention has the effect that an aggregate proppant overturns in the experimental device, the aggregate proppant is stained with a modifying agent uniformly at a high temperature condition, and the agent is cured on the surface of the aggregate to form the modified proppant. The agent contain
