The invention relates to a recycled silicon material selection device, belongs to the technical field of photovoltaic, and aims to solve the problem of low silicon material selection purity in the prior art. The recycled silicon material selection device comprises a rack and a tank body, wherein a feeding hopper is arranged on the tank body; the tank body is internally provided with a first magnetic roller and a power device for driving the first magnetic roller to rotate; the first magnetic roller is rotated counterclockwise; the first magnetic roller comprises a first barrel and a first magnetic system which is arranged inside the first magnetic roller and is arranged in a circular eccentric manner; a silicon material collection bucket is arranged on the left side below the first magnetic roller; a first impurity collection bucket is arranged on the right side below the first magnetic roller; a scraping plate is arranged above the first impurity collection bucket on the right side ofthe first magnetic roller; an impurity collection roller is arranged above the right side of the first magnetic roller; a fixed magnetic system is arranged inside the impurity collection roller; a rotating device for driving the impurity collection roller to rotate is arranged inside the tank body. By adopting the recycled silicon material selection device, primary magnetic selection is carried out through the first magnetic roller, secondary magnetic selection is carried out through a falling plate, then a recycled silicon material after selection has the lest magnetic impurities, and the purity of the silicon material can be effectively improved.
