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.
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.
Single big diameter rotor (750 mm)
Proprietary knife design and material
Variable knife gap to improve separation of steel and rubber
Compact Heavy Duty design+ High throughput rates
Fast and easy tool change and maintenance
Leider gibt es für diesen Aussteller kein deutsches Firmenprofil.
The name ZERMA comes from the German word zerkleinerungsmaschinen, meaning crushing machine. Since the company was founded in 1943, this has remained our mission.
ZERMA has traditionally focused on the development and production of size reduction machinery for the plastics industry. However, today ZERMA has expanded into related industries such as tire recycling, e-waste and wood recycling. Our core strength lies as a machinery and component producer. As such we are an ideal partner for systems integrators and OEM projects.
We remain committed to the improvement and development of size reduction machinery. The ZERMA product consists of three main machine types; granulators, shredders and pulverizers.
Our granulator product lines cover a full range of sizes and applications. We start from the slow speed, beside the press models of the GSL Series, and the compact soundproofed granulators of the GSC Series. These machines are commonly used in injection, blow molding, and extrusion applications. The large GSH Heavy Duty Granulators are also used in these applications as well as high throughput operations and demanding post consumer recycling.
Our second machine category is the Zerma Single Shaft Shredders. Again, we are able to cover a wide range of applications. We offer the small ZBS Series for purgings, the ZSS and ZIS Series for general applications, and the ZXS Series to achieve high throughputs. Our shredder offering also includes the ZWS Series for wood and regenerative fuels.
An important milestone was the development of the ZRS Pipe Shredder Series. These machines allow the processing of pipes with up to 1200 mm diameter and 6 m length without the need for pre-cutting. There is no comparable product available on the market today.
The ZERMA PM Series pulverizers are produced for extrusion and rotational molding applications. We offer a complete range of machines as well as evacuation and screening equipment to insure quality of the finished product.
ZERMA also offers machines for specialized markets. This includes ZHM Series hammer-mills and GRF Series compact granulators fitted with roller feeding devices.
The most recent addition to the ZERMA family of products is the ZTS Tire Shredding System. These machines are designed to process used car and truck tires. We offer complete systems to produce separated crumb or powder.
In order to better service our customers in different markets, we have established ZERMA-Europe, ZERMA-UK, ZERMA-Thailand, ZERMA-North America, ZERMA-Latin America and ZERMA Australasia. These subsidiaries work with more than 100 agencies world wide to ensure quick delivery, optimal service, and timely support. We call it the ZERMA family.
