<p>PROBLEM TO BE SOLVED: To provide a cullet manufacturing machine enhanced in the durability of its crusher roller. SOLUTION: A glass product help between a mesh mesh plate 13 and the outer peripheral surface of a crusher roller 14 is crushed by rotating and revolving the crusher roller 14 on the mesh plate 13. At this time, since the crusher roller 14 has a truncated cone shape having a predetermined taper angle, the angular speed at each point on the outer peripheral surface of the crusher roller 14 is same to or approaches a speed cable of smoothly holding such a state that the axial line of the roller 14 coincides with the radial direction of the mesh plate 13 during the revolution of the roller 14 as compared with a conventional cylindrical roller. As a result, the non-uniform wear degree of each part on the outer peripheral surface of the crusher roller 14 is reduced and the durability of the crusher roller 14 can be enhanced.</p> |
