▎ 摘　　要

NOVELTY - High heat-conducting wear-resistant material involves (i) grinding nano aluminum nitride, graphene, silicon carbide, carbon black, titanium nitride and zirconium dioxide into powder in the crushing and grinding device to obtain mixed powder A, (ii) uniformly mixing and stirring the zirconium corundum fine powder, zirconium oxide fine powder, pure calcium aluminate cement and aluminum oxide fine powder to obtain the mixed material B; (iii) uniformly stirring the mixed powder A and the mixed material B in step (i) and (ii), adding bonding agent to make form, and drying to obtain the blank C; and (iv) placing the blank C in the step (iii) in a vacuum atmosphere sintering furnace, under the temperature of 1500-1900℃, sintering for 40-50 minutes, and cooling to room temperature to obtain the composite wear-resistant material. USE - The high heat-conducting wear-resistant material for use in a mine. ADVANTAGE - The material aiming at the problems in the prior art that only one grinding can be performed, the grinding accuracy is insufficient, and the raw materials of large and small particles cannot be sieved and repeatedly ground. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for a crushing and grinding device of high heat-conducting wear-resistant material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a three-dimensional section view structure of crushing and grinding device of high heat-conducting wear-resistant material. 1Shell 2Fixing shaft 3First rotating plate 5Rotating shaft 6Second rotating plate 8Second grinding wheel 13First grinding groove 14Through hole 15First sieve plate 16Inclined hole 17Second sieve plate 18Return flow passage 19Clapboard 20Rotating rod 24Driving motor 28Circular sieve plate 30Flow guiding plate 32Second grinding groove 33Protective cover 38Feeding port 39Discharge hole 40Guide groove
