Rotochopper launches slow speed shredder line

June 3, 2015 - Rotochopper recently launched a new line of industrial slow-speed shredders. The first model in this new line, the HTS-2, made its debut at Waste Expo in Las Vegas.


The HTS-2 is a dual shaft shredder designed to pre-process stumps, commingled C & D, railroad ties, and other forms of mixed or contaminated waste.

Maximizing the potential of waste materials
The HTS-2 shredder is designed to minimize the costs of turning challenging feedstocks into end products like compost, landscape mulch, and boiler fuel. 

“The introduction of the HTS-2 is the completion of a long-term Rotochopper plan and promise to provide our customers with a complete line of grinders from hammer-mill to hi-torque,” said Vince Hundt, Rotochopper’s co-founder and international sales manager. “To the continuing success of our high speed horizontal grinders and hammer mills we now add the HTS-2 high-torque grinder we have been talking about.”

Streamlined maintenance and rugged reliability
The HTS-2 offers a user-friendly design that is designed to keep shredders in sync with the rest of the user’s processing equipment. The open shredding table allows dirt, stones, and other abrasives to easily pass, reducing wear rates. Grease points and other routine maintenance areas are built to be easily accessible. The aggressive tooth design efficiently pulls in raw material for continuous throughput without a feed ram.

The teeth and counter teeth ensure active shredding in both directions. Weld-on shredding teeth stand-up to contaminants better than bolt-on inserts. 

Designed for extreme duty applications, the radial piston drive motors deliver over 1,000,000 inch-pounds of torque to each shaft in both directions. These radial piston drive motors offer better reliability and parts availability than gear boxes and other systems commonly used to generate the required torque levels.

Flexible for diverse work environments
The HTS-2 shredder is available with diesel or electric power units from 400 to 630 hp, in stationary, portable, or track-mounted configurations; and is designed for seamless integration with Rotochopper grinders.

The HTS-2 shredder integrates with the company’s horizontal grinders to provide effortless fibre sizing of challenging materials. With a Rotochopper multi-stage fibre sizing system, raw waste goes in and a finished product comes out. The shredder outputs a steady stream of material that is optimized for metal removal and grinding. An in-line Rotochopper grinder then refines the shredded material to finished specifications for landscape mulch, compost, biomass fuel, or other materials. With the addition of an in-line Rotochopper hammermill, a Rotochopper multi-stage system can even produce fine texture fibre for animal bedding, fuel pellets, and other short fibre applications.

25 years of Fibre sizing innovation
We launched the Rotochopper brand 25 years ago with a philosophy that waste materials should be viewed as opportunities instead of liabilities. That philosophy helped a broad range of companies transform the nuisance of waste materials into profit centres like coloured landscape mulch, compost, boiler fuel, animal bedding, and hot mix asphalt supplement (from shingles). The introduction of the Rotochopper shredder line helps bring this unique approach to a broader range of raw materials.
