Abstract According to Fourier's law, Newton's cooling law and the relevant parameters of the roller shaft of the roller crusher, the heat conduction model of the roller shaft was established, and the usage of the roller shaft under different working conditions was simulated and calculated. At 600 ℃ operating temperature, the roller shaft was air-cooled and 40Cr material could be used safely. At 850 ℃ operating temperature, the roller material was changed to 0Cr18Ni9, or the roller material remained unchanged, for the cause of safety, the cooling method must be changed to water cooling.
