Aug. 14, 2017 - As the manufacturer of the only patented Grind & Color system, Rotochopper is excited to announce the launch of the Generation 2 Colorizer. “We set the bar for grinding and coloring efficiency with our patented colorizer,” said Art de St. Aubin, Rotochopper President & CEO. “Now we’re raising the bar with the Generation 2 Colorizer.”

The Generation 2 Colorizer builds on the success of the original Rotochopper patent by increasing throughput capacity without sacrificing single-pass coverage. The original colorizer patent gives Rotochopper grinders the exclusive advantage of injecting colorant directly in the grinding chamber, using the force of the grinding process to evenly coat all mulch particles.

The Generation 2 patent enhances this unique color application method by adding a secondary colorant atomization system directly behind the grinding chamber screen. The secondary spray manifold applies colorant to mulch particles while they are spaced apart and travelling at high speed, ensuring even coverage. By contrast, grind and color systems that spray onto the discharge conveyors apply colorant to only the uppermost particles. The ratio of primary and secondary colorant application can be easily adjusted to match different feedstocks and mulch specifications. The secondary spray bar allows for higher production rates without compromising color integrity, even with darker shades like black and brown.

In addition to increased production capacity, the Generation 2 Colorizer provides unparalleled monitoring and control capabilities to deliver consistent mulch quality with minimized operating costs. The Generation 2 Colorizer allows high-volume mulch producers to monitor and fine tune all critical parameters, including colorant usage (by volume and weight), water, throughput, engine or motor load, and infeed speeds.

“To maximize your margins in a premium mulch operation, you must not only optimize production rates and mulch quality on a day by day basis, but understand the numbers that drive your bottom line from year to year,” de St. Aubin stated. “Our Generation 2 Colorizer allows mulch producers to track and fine tune the important numbers from the control panel, your loader cab, or your office. This system delivers a holistic view of your operation, and provides the insight you need to proactively grow your colored mulch business.”

The Generation 2 Colorizer is available for select grinders in 2017, with broader availability in 2018. Some of the components and functions described above are optional.

Rotochopper designs, builds, and supports a complete line-up of horizontal grinders, slow-speed shredders, wood chip processors, asphalt shingle grinders, and mobile bagging systems from our state-of-the-art manufacturing facility in St. Martin, Minnesota.
