PROBLEM TO BE SOLVED: To provide a crushed matter sorting machine capable of making recycling of wastes easier than before by strengthening and stabilizing a fixation solution of heavy metals in the crushed matter of wastes. SOLUTION: The crushed matter sorting machine is provided, on its conveyer portion, with a device for spraying a heavy metal immobilizing solution using a stainless steel pump. The device sprays the solution onto a treated matter sorted by the machine, and the solution efficiently reduces the heavy metal contained in the waste to convert it into an insoluble compound and at the same time enclose it in the inside of high strength solidified body.
