These impressive machines are used in the recycling business to process stumps, logs, yard waste, tires, solid waste and C&D debris into sizes as small as one inch at unparalleled production rates.

Manufactured at our facility in southwestern Idaho, our innovative grinders and metal recycling equipment are shipped throughout the world.  Diamond Z continues to grow and innovate as a leader in the green waste industry.
