Features & Advantages
For over fifteen years, we’ve been recognized as innovators in the grinding equipment industry with several unique machines and patented features. These innovations form the “Perfect In One Pass” difference that defines our customers’ success stories.
This patented system allows operators to grind and color virtually any clean wood fiber virtually any color. The power application system injects water and colorant directly into the grinding chamber to offer the most efficient means of producing colored landscape mulch. Utilizing the force of the grinding process to mix colorant into mulch ensures thorough color application without hassle and waste.
Bale Pre-Processing System
Our unique bale pre-processor separates round or square bales into an even flow of loose material to the grinding chamber, optimizing efficiency and throughput. Fully integrated into the grinder’s control system, the bale pre-processor automatically adjusts its operating parameters according to bale consistency and will actually unroll round bales rather than simply tearing them apart unevenly.
This Rotochopper exclusive allows our horizontal grinders to efficiently process pliable feedstocks that can plug other grinders, like green slab wood, palm fronds, tomato vines, and various forms of agricultural residue. Simple and reliable, with no moving parts to break down, this patented feature lets operators quickly adjust the angle and speed at which feedstock enters the grinding chamber, creating an aggressive feeding angle appropriate for solid materials, and a less aggressive angle for pliable feedstocks.
StopWatch Monitor and Control System
Designed to reduce downtime and damage from severe rotor impacts, our patented StopWatch system stops and reverses the infeed when it detects excessive vibration. Integrated into the electronic control system, the StopWatch system monitors vibration directly from a rotor bearing and records an operating log of vibration levels to help operators manage maintenance and operating practices.
Replaceable Mount Rotor
Simple yet solid, this rotor (patent pending) allows operators to quickly change rotor mounts using only two bolts—no bushings, lock collars, or pins. Its unique design minimizes impact stress experienced by the mounting bolts. If one mount becomes damaged, only one needs to be replaced.
Unequal-length Powerfeed Linkage Arms
This innovative powerfeed lift system (patent pending) keeps the powerfeed close to the rotor throughout its lift path, in contrast to traditional powerfeed arms that widen the distance as the powerfeed rises. This lift assembly can generate remarkable downward pressure with little effort and applies this force close to the rotor, where it is most effective at controlling the feed rate.
90-degree Side Loading Conveyor
When equipped with this option, our horizontal grinders can fill parallel open top semi trailers. The 90-degree side loading conveyor reduces downtime required to position the grinder and trailer in cramped operating environments like forestry landings.
A key advantage of our asphalt shingle grinders, the rotating anvil (patent pending) force feeds a steady flow of raw material to the rotor to allow rapid, yet smooth, grinding. Designed for the abrasiveness and pliability of asphalt shingles, the rotating anvil experiences significantly less wear than typical anvils and enhance grinding efficiency.
Screen Installation System
All of our grinders and chip processors allow fast, convenient rotor access and screen changes with our unique screen installation system. Screens can be changed in as little as fifteen minutes without additional tools.
Each of our horizontal grinders features an aggressive powerfeed drum with deep serrated teeth. Combined with a steel slat infeed conveyor, the powerfeed drum provides controlled feed rates for vastly different feedstocks: whole trees, pallets, wood chips, tomato vines, green slab wood, corn stover, yard waste, and much more.
Steel Slat Infeed Conveyor
Smooth steel slat infeed conveyors give our grinders the capacity to efficiently feed diverse feedstocks with less spillage and wear than drag chain conveyors. Our unique infeed transition system allows raw materials to flow smoothly from the infeed conveyor to the grinding chamber, preventing loose particles from falling directly onto the collection conveyor and decreasing finished product value.
Rotor, Tooth, & Screen Designs
A key to our “Perfect In One Pass” advantage is our focus on screen and tooth design. The right screens and teeth are essential to finished product control, and we offer a wide selection to maximize the versatility of our grinding equipment.
Advanced Electronic Control Systems
We use state of the art control systems to provide superior equipment control, monitoring, and diagnostic capabilities. User-friendly and reliable, our controllers take the guess work out of equipment settings, allowing operators to quickly make accurate adjustments to infeed speed and other settings.
Each of our grinders comes standard with a grinding chamber water injection manifold for suppressing dust. Injecting a small amount of water directly into the grinding chamber provides effective dust control. Our colorizer system provides the same dust control benefits. We offer several additional dust control options for sensitive environments; please call for details.
We use OEM components from industry leaders like CAT, PT Tech, and Flexxaire to guarantee the best combination of performance, reliability, and customer support. These OEM solutions allow us to suit the unique challenges of each customer with practical technology that is backed by world-wide service.
