DOPPSTADT AK 640 K Mobile Waste Grinder

MADE FOR BIG TASKS
With a new, even more powerful main drive, the robust chain drive and the 7.5 m long rear conveyor with a discharge height of over 5 m, the AK 640 K is designed to meet the highest demands.

APPLICATION
- Old wood
- Green waste
- Compost
- Commercial waste
- Substitue fuels – EBS
- Agricultural residues

SPECIAL FEATURES
The AK 640 K fine shredder is equipped with completely new stainless steel piping for the exhaust system. The exhaust aftertreatment system is optimally thermally shielded by means of integral insulation. The optimized diesel engine from MTU offers an increase in performance (20 kW and 200 Nm). It has a rated output of 480 kW and fully meets the latest Stage V emissions standard for non-road vehicles.

The successor model to the AK 635 K is characterized by its maximum shredding performance. The AK 640 K can also process very large input material and is moved by a chain drive. If required, it is available in an off-road chassis variant, which increases off-road capability with even more ground clearance. The 3,500 mm wide filling hopper with a loading height of 2,220 m and the 7.5 m long and 1.5 m wide discharge belt with a discharge height of over 5 m make the AK 640 K the perfect solution for a wide range of requirements.

The Doppstadt AK 640 K can be used for a very wide range of materials, such as shredding old wood, wooden pallets, green waste, organic waste or logs and roots.

The separate drive of the scraper floor and the pendulum-mounted feed roller ensures optimized material feed. The AK 640 K is extremely easy to maintain thanks to the lowerable rear conveyor as standard, the high diagnostic capability and the easy exchangeability of the components.

ADVANTAGES
- One-man operation (radio remote control of all functions), machine movement via crawler chassis, high mobility in off-road conditions (*optionally also with 200 mm higher off-road chassis)
- Continuous shredding through load-controlled material feed, insensitive to contaminants due to freely swinging flails, latest engine and exhaust technology, compliance with exhaust emission standard Stage V
- Exhaust system made entirely of stainless steel
- Standard lowerable 7.5 m long rear conveyor (discharge height over 5 m) enables shortest set-up times and maximum accessibility and ease of maintenance to the flail drum, tools or rear basket
- Separate drive of scraper floor and pendulum-mounted feed roller for optimal material feed and high throughput
- Free-swinging flails of the flail drum, with a flywheel mass of approx. 2.5 t, have quickly individually exchangeable flail tips that are adapted to the material (e.g. hard metal or armored tips)
- Special baskets* with 3D technology for the use of old wood for more structure in the final product (*optional)
