Blue Diamond's line of drum mulchers features models heavy-, extreme-, and severe duty, with cutting widths ranging from 30 to 50 inches. Mulchers are compatible with compact, mid-sized and full-sized excavators ranging from 4 to 20 metric tons
Cutting capacities range from 4 to 7 inches, and models are available to work with excavator auxiliary hydraulic flows from 9 to 45 gpm.
Many components, including the frame, are made with high-strength structural steel, and the frame of each model has been reinforced for added rigidity and strength, according to the company. Parts exposed to wear, like the skids and counterblades, are built from wear-resistant steel.
Counterblades on the heavy and extreme duty models are heat treated and reversible. The severe duty model features rigid counterblades more suited for aggressive working conditions.
All mulchers feature an adjustable input counterblade that can be brought closer or moved away from the rotor depending on the finish operators require.
A manual door is available on the heavy duty model, while the extreme and severe duty models feature a hydraulic door. A closed gate results in finer mulch, while and open gate cuts faster. The extreme and severe duty models also feature and extra counterblade on the hydraulic gate that can produce an even finer finish.
Mulchers also feature a rotor design that equally distributes material to the teeth to promote even wear, according to the company. Only one tooth hits the material at a time in this design, resulting in lower power consumption and faster motor recovery.
The heavy and extreme duty models come with one and two rows of chains each, while the severe duty model comes with four chain curtain rows and rubber side shields for extra protection.
