Doppstadt combines modern recycling technology
The stationary processing plant combines modern Doppstadt technology in order to transform unprocessed garbage, industrial, bulky and residual waste into a combustible substitute fuel.

The final product of this plant – a fluff – can be used in cement works, waste incinerating plants and waste to energy (WTE) plants.

A decisive advantage of the Doppstadt processing plant is the economic efficiency. Depending on the components and the desired grain sized, it is possible to achieve throughput capacities of 5-15 tons per hour and per processing line.

Efficient pre-shredding –
A decisive advantage of the Doppstadt technology
The unprocessed input material consisting of industrial waste and garbage is pre-sorted during the first step of operation. Coarse foreign bodies such as electric motors, oil barrels, large iron pieces, tires and reinforced concrete lumps are separated.

Then a Doppstadt single-shaft high-torque shredder is used. This robust shredder pre-shreds the separated input material. During a second phase of operation, a strong over band magnet separates the iron pieces from the material.

Note: For incineration procedures with blowing-in systems, an oversize separation can be used as a precaution against obstructions

Precise grain size production
With Doppstadt technology – a decisive advantage

The pre-shredded material is screened by the Doppstadt Trommel screen and transported to the hard material separation. Non-iron metals, stones, bulky plastic and similar materials belong to the undesirable hard material fraction. The hard materials and the minerals are separated from the pre-shredded material by the ballistic separator. Depending on the quantity, another separation can be carried out. Furthermore, the mineral fraction containing organic material can be after treated by an aerobic process.

The resulting light fraction is shredded by the Doppstadt fine shredder DW 2860 to the required grain size. The DW 2860 Duplex equipped with a aggressive hard metal tools is ideally suited for shredding soft and elastic materials. The precisely regulated material reduction cutting of the fine shredder enables the production of a very small grain size.
