The processing of the tyres into rubber granule is carried out by cold mechanical grinding , which guarantees that the final product is of a high quality and easy to sell. It also reduces the fire risk considerably.
In this plant it is designed to process a mixture of 50% car tyres and 50% truck tyres.

BEAD EXTRACTION

It is only necessary to debead truck tyres not car tyres.
A Debeader removes the steel wire or bead from the internal rim of the tyre for easy recycling and to prolong the life of the blades.

FIRST STAGE: PRIMARY SHREDDING

The tyres go through a rough shredding process first in a primary shredder with 100 mm width blades then afterwards through a secondary shredder 50 mm blades.
The final result is a “rough cut shred” which eases the workload of the first granulator, increasing its productivity and blade life.

GRANULATION

The rough-cut shreds are then loaded, on twin conveyor belts, into the two granulators.
The output is a rubber granule of a maximum 15 mm size, which is separated from the steel wire.

MAGNETIC SEPARATION

The granules then go under the magnetic separator where the 95 % of the steel is removed and carried away on conveyor belt into a skip or similar collection point.

FINE GRANULATION

Three granulators, with rotating blades, reduce the granule from 15 mm to 4 mm.

FLUFF REMOVING OPERATION

Rotary Fluff Screen is used to remove the nylon fluff from the rubber granules. The screen is a fully enclosed rotating drum screen. This is used in conjunction with all the air filters from the granulators and the fine granulators to remove at least 97% of the nylon content in passenger tyres.

GRANULOMETRY SEPARATION – Size Separation

Using vacuum system the granules are transferred onto a vibrating screen where the first two sizes of granules are separated.
Then, the remaining granules go onto a flat screen, which quickly removes all the remaining textile or fluff. Then it is carried onto the last vibrating screen for the separation and storage of the smallest granules.
