The invention discloses a mechanical type industrial particle raw material screening device. The mechanical type industrial particle raw material screening device has the advantages of being reasonable and simple in structure, low in production cost, convenient to install and capable of effectively removing impurities in industrial raw materials. The raw materials enter the mechanical type industrial particle raw material screening device from a first feeding opening, a drive motor drives a rotating shaft to rotate, upper blades and lower blades rotate, fine particles are sequentially filtered by a large-pitch filtering screen net and a small-pitch filtering screen net, large particles are discharged from an upper discharging opening and a small discharging opening, a circulating fan exhausts dust in a screening chamber, the raw materials enters a metal removing chamber for metal impurity removal, the raw materials are conveyed into a cleaning chamber for cleaning from a conveyance chamber, and finally the raw materials enter a spin-drying cylinder in a spin-drying chamber to be dried finally.
