Herbold EWS-R Single-Shaft Shredder

Recycling large-diameter plastic pipes and long profiles requires specialized shredding technology. Conventional shredders often struggle with the size, weight, and geometry of these materials.

Developed specifically for pipe and profile recycling, the Herbold EWS-R Single-Shaft Shredder combines robust construction, intelligent feeding technology, and optimized cutting performance. Designed for high-capacity operation, the EWS-R handles thick-walled pipes, thin-walled profiles, and extrusion scrap while delivering homogeneous output with minimal fines generation.

Built for Large Pipes and Challenging Geometries

The EWS-R is engineered specifically for the recycling of large-diameter plastic pipes and long profiles that cannot be handled efficiently by standard shredders. Available in different machine sizes, the system processes pipes with diameters of up to 1,200 mm and accommodates virtually all commonly encountered pipe lengths. Whether recycling HDPE, PP, or PVC materials, the EWS-R offers a reliable and economical size-reduction solution for both production scrap and post-industrial waste.

Intelligent Feeding for Continuous Productivity

A key feature of the EWS-R is its integrated feeding concept, which combines a large feeding trough, a hydraulic feeding ram, and the shredding unit into one highly efficient system.

Material is loaded into the feeding trough and automatically conveyed into the shredding chamber. The hydraulic ram continuously adjusts the feed rate according to machine load, ensuring controlled material intake and optimal cutting conditions at all times.

This intelligent process design delivers several important advantages:

• Consistent and high throughput
• Continuous material feeding to the rotor
• Reduced wear on cutting components
• Low fines generation
• Improved overall productivity

In addition, the feeding system allows operators to pre-load material while shredding is already in progress, minimizing downtime between operating cycles and maximizing plant utilization.

High Throughput Combined with Low Fines Generation

The EWS-R has been designed to achieve high throughput rates while maintaining excellent material quality. Depending on the machine configuration and application, capacities of up to 7.5 t/h can be achieved.

Its heavy-duty cutting rotor and optimized knife geometry ensure efficient size reduction and produce a homogeneous output with minimal fines content. This creates ideal conditions for downstream recycling processes.

Different rotor and knife configurations are available, allowing the shredder to be adapted to specific materials, throughput requirements, and operating conditions.
