RECYCLING OF CONCRETE RAILWAY SLEEPERS

Ready for any challenge

RESOURCE-EFFICIENT AND ECONOMICAL

In order to maintain the load-bearing capacity of the railway network, several million concrete railway sleepers are replaced annually across Germany and Europe.

The sleepers are made of high-quality concrete, which, depending on the country and design, contains reinforcement steel, L-steel, pipes, etc. In addition, from a recycling perspective, “foreign materials” such as wood and metal may be present.

Challenges in Railway Sleeper Crushing

WE HAVE THE SOLUTIONS

Recycling concrete railway sleepers presents various challenges, for which our double roll crushers provide refined and economical solutions.

EFFICIENT HANDLING OF LONG SLEEPERS

Despite their length, the sleepers can be fed whole or 2-3 at a time using a grab into our double roll crusher. The labor-intensive cutting of the sleepers is no longer required.

LOW WEAR

The high iron content in and around the sleepers poses significant wear potential to the crushing technology. Our double roll crushers rotate at low speed but with high torque, resulting in very low wear compared to other crushing techniques.

NO MACHINE DAMAGE OR INTERRUPTIONS

Large iron components can cause machine damage and interruptions. The built-in overload protection through hydraulic gap adjustment ensures smooth and continuous operation.

GENTLE CRUSHING – HIGH-QUALITY AGGREGATES

A high content of filler and sand complicates the reuse of concrete and reduces the economic efficiency of recycling the sleepers. Our double roll crushers gently crush the material, ensuring a high percentage of valuable aggregates in the recycled concrete granulate with minimal fine and sand content.

EASY SEPARATION OF FOREIGN MATERIALS

Crushing techniques operating at high rotational speeds shred foreign materials like plastic or wood to the point where they become difficult to remove from the recycled material. The gentle crushing action of our double roll crusher preserves the size of foreign materials, allowing for easy separation.

CLEAN SEPARATION OF CONCRETE AND STEEL

Our double roll crushers achieve nearly 100% exposure of the tension wires, allowing for a clean separation of materials.

High-Quality Secondary Raw Material

FROM CONCRETE RAILWAY SLEEPERS

Our double roll crushers from the DRC series are used in the recycling of railway sleepers. Equipped with hydraulic gap adjustment and overload protection, they are ideally suited for the production of high-quality secondary raw materials from discarded sleepers.

Final grain sizes of less than 80 mm can be achieved. For high-quality processing into granules <16 mm as a concrete aggregate, our SGC series is used.

A throughput of 150 t/h and more is realistically achievable, depending heavily on the operator’s ability to quickly feed the concrete railway sleepers into the crusher using a grab.
The double roll crusher can be offered both as a stationary and mobile solution.
