Step 2: Granulation

After the shredder has cut the tyres into big chips, they continue through an intermediate storage to the first granulator, which steps them further down to approx. 1.5 cm Already at this point 80-90% of the steel has been separated by the use of a magnetic system.
 

The main material, which now predominantly consists of rubber containing small amounts of steel and textile, is transported further on and separated into two fractions. The smallest particles are transported directly to step 3, where they are sieved and rinsed. The biggest particles go through a new granulation until they are small enough.
