JUST HAMMER IT WITH A BANDIT HM6420!
Since 1983, Bandit has manufactured equipment for a multitude of wood waste and recycling markets. The vision, from the beginning, is to build quality, highly productive, easy to maintain equipment providing years of dependable service. The commitment for quality, innovation, and dedication is instilled in every employee and is one of the main reasons why Bandit became an Employee-Owned Company (ESOP) in 2018. These core values ensure each Bandit machine will leave the factory ready to exceed your expectations.
Bandit introduced its first horizontal grinder, the Model 3680, in 1995. Since then, multiple models have been engineered and manufactured featuring a unique cuttermill for processing a diverse range of material. Expanding the horizontal grinder line in 2024, Bandit introduced its first hammermill grinder (Model HM420) further enhancing Bandit鈥檚 already expansive line of horizontal grinders.
The Bandit team was excited to bring this highly productive 40鈥� capacity grinder to market. This machine was designed and manufactured to accommodate those grinding applications that may contain contaminants. A Caterpillar C32, 1,200 horsepower engine provides ample torque and horsepower for optimal machine performance and productivity.
The heart of the HM6420 is a 50鈥� diameter x 66鈥� wide hammermill. The heavy-duty mill features 1.75鈥� drum skin custom formed from rolled plate. The drum is supported by a 7鈥� main shaft constructed of alloy steel that has been ultrasonic tested. Each pocket within the drum is manufactured from high strength A-514 steel. These combinations create a structural sound mill for added durability and integrity. The mill is equipped with twenty carbide infused hammer inserts built to withstand the toughest material fed into the machine. Each holder is securely attached to the mill via a patented quick change pocket system. Each holder recesses into the mill pocket, increasing durability. A top plate covers the pocket and held in place by six hex bolts. The hammer insert is attached to each holder utilizing two bolts. With this set-up, the mill hardware is easier and quicker to replace.
An impact detection system is standard and designed to limit damage if a contaminant is struck inside the grinding chamber. Once an impact event is detected, the grinder will idle down, open the gate, disengage the clutch, and reverse the feed.
A heavy-duty slat-style infeed conveyor is standard and is extremely durable and easy to maintain. It features an impressive feed rate of up to 132 FPM! The conveyor is direct drive generating over 18,000 of pulling power. The large diameter feed wheel is also direct drive and capable of producing over 17,000 pounds of down pressure. These combinations empower the HM6420 to grind massive quantities of material efficiently and effectively at once.
Three screens are utilized to achieve the desired end product size. Available size ranges include from 1鈥� to 10鈥� hole sizes and are available in modified diamond, round, and hex configurations. The HM6420 can be ordered with an optional screen cradle simplifying the screen changing process. The screens cradle will hold the replacement screens, and the existing cradle can be pulled from the machine and swapped with a new cradle holding the new desired screens.
Proportional feed is standard and regulates the feed system. As the engine begins to lose RPM, the feed system will slow down based on various settings in the Bandit control system. This system gives adequate adjustments to effectively process material of varied sizes allowing each unit to create a more consistent end product.
A wireless radio remote control system is standard on each grinder and will control all grinding functions. On track units, the remote will control all track functions and feature an LCD screen that will display engine coolant temperature, engine oil pressure, engine load %, engine RPM and battery voltage.
