The Process of Tire to Rubber Granules

Times:2017-02-23   Author:zhengyangtire

The Process of Tire to Rubber Granules is a three-stage processing primarily shredding, after that granulation and lastly fine grinding through which high-quality materials for recycling are ultimately produced.

Shredding:

The very first step involved in the recycling of tyres is shredding. Shredding means separation of wire and mesh from tyre and breaking them into pieces. This can be obtained by a machine with moving parts in which used tyres are put and steel or iron made wires are separated out from the tyre after this tyre is torn to pieces. The machine is very versatile which can also be used for shredding of all kinds of input materials and is well suited for different industries. The diameter of rotors ranges from 457 mm -850mm to 2000 mm width which are driven by either one or two oversized gearboxes. There is a well integrated hydraulic power pack into the machine housing which is used to save space and protect it from damage but is still easy to access or remove for maintenance.

Granulation:

The granulators are used in the next step of this recycling process in which pieces of waste tyres are grinded in the large sized granulators to produce large quantity of granules. Granulators are developed as slow-running grinders for applications in the injection and blow molding sector. The material which has to be granulated is fed via a sound-absorbing feed hopper which is available in a wide range to suit the application. The slow-speed granulators which are designed of this range are commonly mounted on either low or high level base frames. With these numerous options, the slow speed granulators can be tailored to an extremely wide range of applications.

Pulverizer:

The last step involved in the production of rubber powder from tyre waste is to convert the granulated material into the fine powder. This is done by means of pulverizes. Pulverizes are high speed, precision grinders which are used for the processing of medium hard, impact resistant and friable materials. The granulated material is introduced through the centre of a vertically fixed grinding disc which is mounted concentrically with an identical high speed rotating disc to make the fine powder of it.
