Single shaft shredder ZERMA ZRS

ZERMA ZRS series shredders have been developed for the size reduction of pipes up to 1,300mm diameter from materials such as UPVC, PE and PP.

General description

The ZRS shredder is the world’s first single shaft shredder capable of handling large diameter pipes (up to 1200mm dia ) without the need for pre cutting. 

Since their introduction they have become the per se standard for pipe shredding and are used world-wide by leading pipe manufacturers. 

More than 200 installations demonstrate our technological leadership in this market and our continuing innovation is based on market demands and customer feedback. 

Dependent on pipe diameter, the ZRS rotor diameters and widths range from 800mm up to 1500 mm. 

The standard hopper accepts pipe lengths of up to 6 m. 

The combination of advanced controls, low rotor speed and smooth hydraulics create a reliable and easy to use system.


The main focus of the ZRS shredders is the shredding of large diameter pipes or bundles of smaller pipes and profiles made from HDPE, PP and PVC.

The machines can also be used for recycling of other plastic materials such as large lumps, stacked wheelie bins and pallets etc.

In combination with other ZERMA size reduction equipment such as granulators and pulverizers we are able to provide a complete turn-key recycling solution.
