PURPOSE: Provided is a waste treating machine which crushes a lump of concrete with large granularity two times continuously within a selection net tub so that it accelerates speed in separating concrete particles and lump. CONSTITUTION: In the waste treating machine which consists of the selection net tub(22) to rotate by a motor, a conveyer belt to transfer the separated concrete particles falling from the selection net tub and a conveyer belt to transfer concrete particles with large granularity passed through the selection net tub, the waste treating machine is characterized by including a crushing bar(24) in a length direction wherein the selection net tub is projected inward at the internal circumference wall.
