Rotochopper RG-1 Shingle Grinder

"Perfect in One Pass". You won't find anything like it on the market - a machine designed specifically to grind asphalt shingles. Typically, the machines used to process shingles are designed for wood waste. Several companies offer optional components to modify their horizontal grinders or tub grinders for grinding shingles, including special teeth and auxiliary water spray bars to reduce the heat generated by grinding shingles. But because of the vast differences between granite covered shingles and the materials horizontal grinders and tub grinders are designed to handle, Rotochopper started from the bottom up to build a unique match for this demanding application. The result is the efficient, high performance RG-1 shingle grinder.

With production rates of 40 to 50 tons per hour through a 5/8" screen, the RG-1 shingle grinder reliably delivers a uniformly ground product ideal for hot mix asphalt supplement and other recycling opportunities. Its throughput rates are made possible by unique infeed, rotor, and screen configurations. A load leveler and a high torque agitator prevent bridging and maintain a consistent flow of material toward the rotor. A rotating anvil (patent pending) forces the feed material into the rotor at a controlled rate for accurate sizing and reduced wear. The continuous movement of this rotating anvil increases the wear surface where this initial breakdown takes place, allowing heat to disperse and reducing the material buildup that might otherwise prevent active grinding.

With two radial cut AR35 screens wrapping 270 degrees around the rotor, material can escape the grinding chamber quickly, reducing wear and heat. A spray bar injects precise amounts of water directly into the grinding chamber for cooling, lubrication, and dust suppression. These features result in more production, more horsepower efficiency, less wear, and less operational maintenance.

Like every machine in our product line, the RG-1 shingle grinder was designed and developed through attention to customer needs. The RG-1 is easy to operate, with integrated PLC controls, a low load height, and automatic load regulated feed rates. The screens can be accessed and changed quickly and easily through two access doors that open at the ground level. The high wear cast carbide teeth have two useable faces. A complete set of 38 can be reversed or replaced in one hour by one person.

RG-1 shingle grinder is fully mobile and can be set up in minutes. It is available in diesel or electric configurations, ranging from 400 to 630 horsepower. And its performance is not limited to shingles. Because of its unique design, the RG-1 shingle grinder is also ideally suited for regrind and refinement of biofuel from wood, corn, and many other biomass materials. The RG-1 shingle grinder delivers high production rates as a primary or secondary grinder for many other materials that conform to its mill opening.

The RG-1: a breakthrough new machine for your high volume grinding, regrinding, and refining needs.

Processing asphalt shingles for reuse in hot mix road paving applications is considered by many to be one of the most exciting new profit centers in recycling. There are approximately 11 million tons of new reject and tear off asphalt shingles available for grinding each year. In response to the opportunities and challenges of grinding shingles, Rotochopper offers the RG 1, the only machine on the market designed specifically for this tough application.
