摘要：
A material reduction machine includes a frame, an arm assembly coupled to the frame, and a bearing assembly coupled to the arm assembly adjacent a distal end. A shaft is rotatably coupled to the bearing assembly and has an axis. A comminution wheel is coupled to the shaft for rotation therewith. The comminution wheel is configured to be driven by a drive system and extends outward from the shaft in a radial direction that is perpendicular to the axis. A gap is defined between a portion of the shaft, the bearing assembly, and the comminution wheel, and a guard plate is attached to the bearing assembly or the arm assembly. The guard plate has an axial extent extending along the axis and a radial extent extending radially relative to the axis to at least partially fill the gap. The axial extent and the radial extent lie in a plane.
