Grinders with sensitive infeed

Grinders with sensitive infeed
ProGrind H-3060 horizontal grinders include a Caterpillar C-15, 565-hp diesel engine, and a large-diameter infeed roll that is sensitive enough to permit grass clippings, brush, limbs, pallets, slabs, logs and stumps to be fed at variable speeds for continuous rather than batch feeding.

This grinder is engineered with several cutting surfaces at varying depths, which virtually eliminates the frequent jamming characteristic of more conventional type grinders. Rotating downward, the double cut, 30-inch-diameter by 60-inch-long hammermill momentarily wedges the incoming heads and the cutter bar, limiting the depth of cut. This procedure will prevent wide items from lodging between the screen and the hammermill. Also, this system provides a more efficient cut with a self-adjusting hydraulic clutch. In contrast, shredders using an upward rotating hammermill are reported to be less efficient.

The large diameter feed wheel allows easy access to the hammermill and the changeable screens. The wheel has free-fall restrictors. When raised, the wheel is parked against dual safety stops with a hydraulically operated safety pin. The H-3060 is available on track or trailer mounts.
