Magnum Force 8800 Horizontal Grinder
CBI has unveiled its biggest, most powerful, portable grinder ever produced. On portability, CBI president Anders Ragnarsson, says “It’s not as simple as just throwing wheels on a horizontal hog. For two decades, CBI has engineered equipment that is designed as much for the road (or off road, depending on the model) as it is for aggressively processing material. In this case, the tracks on the 8800 get this grinder to sites that can be difficult in terms of terrain so that it can perform a critical function.” The Magnum Force 8800 features over 1,200 hp, and is designed to process large amounts of full-length logs, brush, stumps, telephone poles, railroad ties, etc. A unique clamshell hogbox opens in seconds with the push of a button – giving full access to the rotor and quick-change screens, and extra-thick shear pins protect the screens and anvil. A large-capacity feed hopper easily handles full-length trees or large material surges with no problem, and the upper-feed roller system and chain-feed conveyor are powered by two heavy-duty planetary and high-torque motors. The 8800’s wide discharge conveyor facilitates high-volume throughput and folds for transport, and a proactive metal-detection and release system provide maximum protection for working parts. Impact measuring sensors on these units detect if a rotor tooth strikes tramp metal, and then communicate with the machine’s main control system which reverses the feed, throttles down the engine, and depending on the impact, hydraulically opens the anvil/grate frame assembly at an extremely high rate of speed, allowing the ejection of the tramp metal. Some other key features include: a forged steel rotor that features teeth that can be adjusted for efficient primary and secondary grinding; CBI’s Replace-A-Face system which allows for easy and inexpensive hammer repair; IntelliGrind technology which yields feed speeds that vary automatically based on engine load; and an optional modem communications system which provides for real-time system diagnostics, analysis and operating program adjustments.
