The Rotochopper Difference

We launched the Rotochopper brand as a solution for transforming wood waste and other resources into profitable end products as efficiently as possible. Unlike the tub grinders and other equipment common at that time, a Rotochopper grinder could turn wood waste into animal bedding or boiler fuel in a single pass. Engineered for precision grinding capacity, Rotochopper grinders stood apart from other machines that were designed for volume reduction without any ability to control particle size.

For more than 25 years, Rotochopper has focused exclusively on equipment that releases the potential of resources like wood waste, agricultural residue, and food waste by efficiently grinding them to the required size and texture. As a factory-direct manufacturer with a focused product line, we channel customer feedback into exclusive features that result in higher finished product quality at lower operating costs.

“Perfect In One Pass”

Amazed by the game-changing simplicity of our colorizer, one of our customers coined the phrase “Perfect In One Pass” to describe the colored mulch he was able to produce with a single machine. Injecting colorant directly into the grinding chamber, our colorizer simultaneously colors the wood fiber while grinding it to final size and texture. This patented system allows a broad range of companies to capitalize on the premium mulch market. From the launch of this system, the ability to grind and color in a single pass has been a hallmark of the Rotochopper difference.

Engineered Fiber Products

Although “Perfect In One Pass” quickly became our trademark in the premium mulch market, it also describes our approach to a wide range of engineered fiber products. The same one-pass simplicity that maximizes profits for mulch producers can dramatically reduce costs for animal bedding wholesalers. The precision grinding capacity trusted by pellet fuel producers helps farmers optimize the palatability of livestock and poultry feed. The need to efficiently convert raw materials to premium products unites these diverse companies that trust the “Perfect In One Pass” advantage.

One Pass for Short Fiber Products

For companies that need to produce animal bedding or other short-length fibers, we offer multi-stage systems that combine horizontal grinders with hammermills to provide seamless fine grinding solutions. In a Rotochopper multi-stage fine grinding system, raw material enters the horizontal grinder, emerging from the hammermill at final size specifications.
