Tub Grinder Information Sheet

Roto Grind uses hardened steel hammers and adjustable shear plates to break materials down by hammer mill instead of expensive screens. No clogged or blown-out screens to service or replace. Roto Grind's reliable tub rotation governing system adjusts for variations in material density and feed rate. Water can be sprayed into the mill area to control dust.

The uncomplicated rugged design makes Roto-Grind dependable, it's ready to work when you are. Down time is minimal and normal service is limited to normal greasing, and occasionally rotating the hammers (or hard face the hammer tips which on Roto Grind can be done with the hammers in place).

Roto-Grind uses your 80 to 200+ H.P. tractor PTO at 1000 RPM, and regular tractor hydraulics. It's easy to move with your tractor's draw bar or even on the highway attached to your pickup hitch. Some rare applications require 540 RPM.

Stationary self-powered models, either electric or diesel, are available for applications that don't require mobility.

The tub is large enough (9 feet wide at the top of the tub or 11 feet wide with a flare kit) to handle round or big square bales. A lower profile tub is also available. The flare kit is needed if you have a very wide loader.

If you have never used a tub grinder and seen it get into the work, you owe it to yourself to see a demonstration. Even if you intend to use it as a simple chipper shredder or to replace wood chippers, our tubs are tops.

Why grind? Give me some examples.

• HAY: Mill any hay, wet or dry, into your mixer wagon or straight into feed bunks.
  • Save wear and tear on your mixer wagon
  • Better feed acceptance
  • Less hay wasted
  • Grind to proper length for good rumen health and cud chewing
• GRAINS:Break hard grains to improve digestibility, lessen pass-through.
  • Corn: ROTO-GRINDing is cheaper than rolling
  • Bearded grains: Use grain cultivars that would otherwise cause lump jaw
• ALTERNATIVE FEED: Use nutritious unconventional feeds that would otherwise be considered agricultural waste, or that are better ground and mixed with hay.
  • Prune pits
  • Carrots
• GREEN WASTE: Turn a waste problem into valuable mulch, compost, or soil amendment.
  • Vineyard and Orchard prunings
  • Municipal green waste
  • Bean and rice straw
  • Nursery waste
• WOOD WASTE: Turn a cartage problem into valuable wood chips for landscape mulch or co-generation fuel
  • Broken Pallets - our tubs make excellent grinders for pallet waste.
  • Orchard limbs and small stumps
  • Construction debris

No. 1 Alfalfa Even expensive, quality feeds can be improved by grinding, and can extend the service life of the augers and chains on your feed wagon. Properly ground hay has better acceptance and digestibility, and that means more milk or beef for your feed dollar!

Wet Hay Once it's wet the clock is ticking, the longer it sits the worse it gets. Grind that wet hay and improve the palatability so your stock can turn that "wreck" into dollars.

Carrots Carrots can be ground and mixed with other forage to make a custom ration. Using seasonally available alternative feeds to augment your ration can be economical with good palatability and acceptance.

Wood Chips Turn orchard waste into a profitable second crop! Wood chips for mulch or sale to power co-generation plants can save the expense of disposal or even generate a profit when the costs of conversion are as low as Roto-Grind can help them be.
