The abrasiveness, pliability, and cohesiveness of asphalt shingles make it one of the most challenging materials to recycle efficiently—unless you have the controlled wear and consistent uptime of a Rotochopper shingle grinder.

Asphalt Shingle Recycling

Rotochopper shingle grinders are packed with exclusive features that add up to one simple difference—a lower cost per ton of finely ground shingles. Before we engineered our first shingle grinder, we worked directly with customers to develop the features that make Rotochopper shingle grinders more user-friendly and cost-effective for recycling reject and tear-off shingles than any other grinding or shredding equipment.

Lower Wear Costs

For companies that need to grind more than just asphalt shingles, our multi-purpose shingle grinders bring advantages to companies grinding asphalt shingles in addition to yard waste, wood waste, and other feedstocks. A Rotochopper grinder with high abrasion package offers lower wear costs and more uptime than the wood grinders typically used to recycle shingle waste.

End Product Challenges

State and provincial DOTs typically specify a maximum particle size of 1/2″ (12 mm) or 3/8” (11 mm) minus for RAS used in public road surfaces. Fine grinding an abrasive feedstock can quickly CAUSE significant wear and downtime —unless you have the controlled wear and simplified maintenance of Rotochopper shingle grinders.

Rotochopper Advantage

Once you have experienced the challenges of shingle recycling, you’ll understand why we developed an extensive line-up of shingle grinding equipment with exclusive features. Once you see the Rotochopper advantage in action, you’ll understand why Rotochopper is the most trusted name in asphalt shingle recycling
