Raw material sorting device for machining and process

The invention discloses a raw material sorting device for machining and a process. The raw material sorting device comprises a support, a concentrating hopper is arranged on the support, a material falling hole is formed in one side of the concentrating hopper, the position, located at the material falling hole, of the concentrating hopper is connected with a plurality of material sliding rails, a plurality of sorting mechanisms which are connected with one another are arranged between the material sliding rails and discharging rails, the steering device is arranged on the support, and a receiving groove is arranged on the support. According to the raw material sorting device for machining, the concentrating hopper is arranged on the support to concentrate steel balls with the size needing to be detected, then the steel balls fall down through the material falling hole, the falling speed is controlled through a speed control device, the falling steel balls enter the sorting mechanisms through the material sli
