Secondary-shredding

Precision secondary shredding takes pre-processed and sorted materials and reduces them to the exact particle size required for downstream recovery or end-use markets. This step is critical for maximizing material value and improving overall system efficiency.

Secondary (fine) shredding also plays a key role in producing high-quality refuse-derived fuel (RDF) for waste-to-energy applications. In addition, it ensures secure, irreversible destruction of confidential documents, hard drives, and data storage devices.

Single-shaft shredder

The XR, equipped with the C or XC cutting systems, delivers consistent output sizes ranging from 1 to 5 inches (25–130 mm), making it ideal for efficient downstream processing.

For applications requiring finer particle sizes, the LRK series produces material in the 0.6 to 1.6 inch range (15–40 mm).
