- Model HD-8 - Heavy Duty Granulators



The HD-8 scrap grinders are specifically designed and built to granulate either large parts or high volumes of scrap material. With its large throat size of 24' x 36', offset cutting chamber and rugged construction, large molded parts can be readily granulated without the need for pre-cutting.

  • It is an ideal machine for applications such as post consumer scrap recycling when equipped with our optional high throughput rotor and screen package.
