Tub Grinder Wear Parts & Screens

What are Tub Grinders & Wear Parts

Tub grinders are a type of equipment used in forestry, landscaping, and agricultural industries to process organic material such as wood, brush, and cornstalks into smaller pieces.
Most commonly, the tub grinders we provide wear parts for are for hay grinding. Tub grinders used for hay typically have a drum that feeds the material into the free-swinging hammers and then goes through a grinder screen. The result is then used as livestock feed or bedding.
