NOVELTY - The utility model claims a graphite material circulating crushing device for graphene floor heating, comprising a crushing box; the inner part of the crushing box is provided with a clapboard one and a clapboard two; the clapboard one and the clapboard two are divided into a crushing cavity one from up to down; a crushing cavity two and a collecting cavity; the inner part of the crushing cavity I is provided with a fixing roller and a rotating roller; the fixing roller is installed on the upper surface of the clapboard one; the rotating roller is set in the fixing roller; the upper surface of the crushing box is installed with a motor and a feeding pipe. The utility model is provided with a fixing roller; a rotating roller and a crushing cutter; using the rotating shaft I to drive the rotating roller and the crushing cutter to rotate; when the rotating roller rotates in the fixing roller, the graphite material can be effectively crushed by the gradually reduced distance from top to bottom; at the same time, the crushing cutter is synchronously rotated with the rotating shaft to further crush the graphite material; reaching the double crushing effect; the crushing precision is high.
