The ZTS and ZTTS single-shaft shredders are specially designed for the processing of complete and pre-shred tyres. Both machines feature a 750mm diameter rotor ranging in width from 1500-3000mm with oversized outboard bearings and twin gear drives. The tangential infeed ensures an optimal feeding of the input materials while eliminating the need for a hydraulic feeding system. All Zerma tyre shredders are equipped with a complete wear package including hard-facing, special knives and wear plates made from highly wear resistant steel. The modular design makes it easy to integrate either machine into existing installations. The twin rows of stator knives and screen in the ZTTS enable it to take tyre shreds down to any required size >20mm. The unique machine design combined with the variable cutting gap create an optimal separation of rubber and steel fractions. The ZTS series is also used in the conditioning of RDF and other alternative fuel applications.
