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

The successor model to the AK 635 K is characterised 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 version, which increases its off-road capability with even more ground clearance. The 3,500 mm wide feed hopper with a loading height of 2,220 mm and the 7.5 m long and 1.5 m wide discharge conveyor 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 the shredding of waste wood, wooden pallets, green waste, organic waste or trunk and root wood.

The separate drive for the scraper floor and the pendulum-mounted feed roller ensures optimised material feed. With its standard lowerable rear belt, high diagnostic capability and easy-to-replace components, the AK 640 K is extremely easy to maintain.
