BiG X 680 | 780 | 880 | 1180
The chopping assembly
- KRONE chopping drums with 20, 28, 36, 40 or 48 blades
- High inertia: enclosed 660 mm (2'2") diameter drums
- Bespoke 800 mm (2'7") wide drums for the BiG X 680, 780, 880 and 1180 models
- Extremely fuel-efficient courtesy of a high inertia and pulling cuts
Matching the drum dimensions to the forager model and choosing the optimum number of blades not only boosts machine power but also makes the forager more flexible to suit more applications. The wide range of OptiMaize drums that are available for BiG X deliver top-quality chops in versatile applications anywhere in the world.
The material is pulled over the blades: The blades on the KRONE chopping drums are arranged chevron-style and at an angle of 11° relative to the counterblade. This arrangement makes for a continuous crop flow, extremely quiet running and maximum efficiency.
Cutting Edge: To ensure a good quality cut, the blade and the counterblade must be set to the correct gap. The blades are quick and easy to align using the eccentric plate.
Body guard: The blade bar protects the closed drum body from wear.
40-blade drum for OptiMaize S: With its higher throughputs and lower fuel consumption per tonne of chopped maize, the 40-blade Biogas cylinder pays for itself in no time. The extremely short chops of 2.5 mm to 15 mm ferment at a higher rate and increase the gas yield, allowing farmers to produce more biogas from a smaller fi eld.
High frequency of cuts: 40 blades can achieve an impressively high cutting frequency. So the Biogas drum cuts harvesting time and increases throughput – even when producing short LOCs.
Chopping the crop to short lengths, the KRONE Biogas drum with 40 blades increases throughput by nearly 25% over what is achieved by a standard 28-blade drum. At the same time, fuel consumption drops by approx. 16% per tonne of chopped material.
48-blade drum for OptiMaize S: Delivering a 20% higher cutting frequency than the 40-blade drum and a theoretical LOC ranging from just 2 to 12 mm, this Super Biogas drum with 8 blades produces an even shorter chop, Boosting gas yields and throughput at the biogas plant even further and reducing fuel consumption per tonne of crop with the same LOC.
