End-of-life tyres are a challenging type of waste since they are difficult to shred and are expensive to treat and get rid of. However, tyre derived fuel TDF is an extremely good alternative to the traditional fuels used in cement kilns, like oil, coal, and petroleum coke. The following blog presents a solution and explains how TDF can be used for heating cement kilns. 

The calorific value of tyre shred is high and it has nearly the same heat value as oil. But what other benefits are there in utilizing tyre shred as a fuel?

Utilizing TDF saves significantly in fuel cost as traditional fuels can be replaced with cheaper tyre shred that has almost equal heat value to oil and is even 25% more effective than coal.

Compared to the typically used refuse-derived fuel (RDF) or solid recovered fuel (SRF), there is less variability in tyre derived fuel (TDF), which makes the burning process easier to manage.

The number of end-of-life tyres is growing globally and at the same time many countries are banning the dumping of tyres in landfills. Thus, there is a huge amount of precious raw material—which many consider problematic waste—available basically everywhere.

Using TDF in cement kilns reduces emissions of nitrogen oxides NOx and costs since less urea is needed. In addition, emissions of particulate matter are lower.

Yes, tyre shred is a good alternative fuel in cement kilns. And there is a feasible solution for producing it. 

TANA Shark industrial waste shredder shredding end-of-life tyres

Why TANA Shark is an excellent machine for producing tyre derived fuel (TDF) from end-of-life tires

The high-torque TANA Shark shredder is perfect for processing end-of-life tyres and producing TDF suitable for use in cement kilns. These four characteristics make it the perfect choice for this task: 

Optimal particle size: You can easily adjust the particle size of the tire shred to the required size within a 50–500 mm range. The optimal particle size is dependent on the feeding method, mixture used, and the technology of your cement kiln. The particle size produced can be adjusted by changing the screen and adjusting the number of counter-knives. With the TANA Shark’s side door, this can be done in minutes.

Good shred constitution: TANA Shark removes steel from tyres very effectively and the small number of steel remnants is good since steel is a source of ferrous sulfide needed in cement production process.

Smoother shredding process: Typically, tyres are shredded in three phases and with several machines. With TANA Shark, you can do everything with one machine in only two phases.

Unique versatility: While TANA Shark is great at shredding tyres, it can also shred other waste materials.
