top

General Description

The ZTS and ZTTS single shaft shredders are specially designed for the processing of complete or pre shred tires.Both machines machines feature a 750 mm diameter rotor ranging in width from 1500 to 3000 mm with oversized outboard bearings and twin gear drives.The tangential infeed ensures a optimal feeding of the input materials while eliminating the need for a hydraulic feeding system.All tire shredders are equipped with a complete wear package including hard facing, special knives and wear plates made from highly wear resistant steel.The two model ranges differ in the amount of stator knives and the screen sizes used. The modular design makes it easy to integrate either machine into existing installations.

Applications

The ZTS with its single row of stator knives is used to pre shred complete car tires or large chunks of pre processed tires down to a size of about 150 mm.The twin rows of stator knives and screen in the ZTTS enable it to take the tire shreds down to a any required size > 20 mmThe unique machine design combined with the variable cutting gap create an optimal separation of rubber and steel fractions when the machine is used with a 20 mm screen. Therefore steel can be removed easily in the following process with magnetic separation equipment. Beside tires the machines are also used in the conditioning of RDF and other alternative fuel applications.

Advantages

Details

The ZTS and ZTTS shredders are equipped with a large diameter flat rotors with weld on hard facing. The knives are fixed in special knife holders fitted in machined pockets.
The ZERMA tyre shredders use special highly wear resistant tungsten carbide flat knives, these knives ensure a long lifetime working with abrasive and contaminated materials.
The oversized gearbox driving the rotor is supported by a very sturdy torque arm cushioning the shocks created while grinding.
