HD-6 Granulators

Above is an HD-6C with an extension and an air relief elbow in a regrind room in a blow molding plant. Trim scrap and scrap bottles are conveyed to the grinder through a scrap duct system utilizing scrap blowers and 10” square duct.

Granulators naturally produce dust, especially with dull knives and improper knife gap. Dust is greatly reduced with the HD-6C. A three-bladed rotor is used to "shear" material instead of "take a bite" out of the material.

Some of the major differences between the two are:

1) Three 16" hi-shear in place of two 18" hook knives
2) Rotary knives are substantially narrower than the cutting chamber to provide clearance to the sideplate so that the knives do not drag bottles against the chamber wall and generate dust.
3) The lower bed knife of the HD-6C was moved to the opposite side of the knife block to change the cutting arrangement with the rotary knives.

Standard Features - HD-6C

1. Large throat will accept oversize bottles.
2. Large cutting area for high thruputs.
3. Designed to reduce fines and streamers.
4. Knives designed to eliminate dragging bottle against chamber.
5. Screen design incorporating edge seals.
