Tryco has represented UNTHA wood grinders since 1984, initially offering the small four-shaft RS30 models for grinding wood to fuel a gasification system.
As the need increased for recycling, waste disposal and particle reduction, the market for grinding and shredding equipment grew, and UNTHA added larger models to its line.
UNTHA’s patented four-shaft ‘one pass’ system keeps the material in the machine until it is small enough to fall through the bottom outlet sizing screen, eliminating the need for trommels and conveyors to return oversize material.
UNTHA also developed single shaft LR and MR models. The innovation of replaceable tooth holders in the slow-turning cutter drum plus a double cylinder ‘banana-shaped’ feed ram distinguishes the UNTHA design.
The smallest model suitable for grinding hardwood pallet pieces has a 27-inch hopper and can produce 1,500 pounds of mulch per hour. The next size model has a 39-inch wide hopper and can accommodate a whole pallet. The LR grinder with a 55-inch wide hopper can produce up to 4,000 pounds of mulch per hour. For larger volumes up to 12 tons per hour, UNTHA offers the MR series of single shaft shredders with hoppers up to 100 inches wide by 70 inches deep.
