Sorting machine

The invention relates to a sorting machine. The sorting machine comprises a shell which is provided with a feeding port for making materials enter an inner cavity of the shell, a particle material outlet and a powder material outlet, and the particle material outlet and the powder material outlet are used for guiding sorted materials out of the inner cavity of the shell; the position of the feeding port is provided with an air blowing port used for spraying out gas flow to change the material moving direction; and a material baffle used for preventing particle materials from being guided out of the powder material outlet and guiding the particle materials to the particle material outlet is arranged above the particle material outlet. Due to the fact that the material baffle is arranged above the particle material outlet, the material baffle collides with materials located above the particle material outlet, and a very good blocking effect is achieved for the particle materials being about to be guided out of
