Abstract：For the study of mechanical friction and heat surface of ignition temperature of dust layer, the experimental study and theoretical analysis method was studied. The results show that the flour dust, polyamide, veterinary medicine powder by mechanical friction heat and light temperature are 310.5, 308.5, 400.3 ℃. The minimum ignition temp erature of dust layer at 298 ℃, 288 ℃and 288 ℃ respectively. Therefore, in the process of production of related companies, the above several dust caused by mechanical friction dust layer on fire accident risk is bigger, need to improve the production process of van measures to prevent dust explosion.
