Waste to Flame

Waste to Flame solution is designed especially to meet the needs of Cement Kilns for recovered fuels production and handling. The turn-key solution includes the complete process from receiving waste to feeding it to the kiln. In Waste to Flame solution BMH Technology’s knowledge of fuel handling and technology of waste processing are combined together as efficient and reliable process solution.

Process overview

TYRANNOSAURUS® Waste Refining Process – the smartest and strongest waste-to-fuel process in the world.

1. Pre-shredding
Optional for low quality waste, Pre-shredding and organic separation
2. Shredding
The heart of the process is the shredder. TYRANNOSAURUS® shredder can handle even as much as 50 tons of waste in hour to as small as 80 mm particle size. TYRANNOSAURUS® shredder protects itself intelligently with MIPS® (Massive Impact Protection System), which automatically rejects unshreddable particles. ZeroCap® hydraulic knive adjustment guarantees right particle size and continuous maximum capacity.
3. Preparation

Separation of fines, metals and heavy fraction. Optionally size reduction to main burner size (<25mm)

4. Fuel Storage
Totally closed dust-free, first in - first out automatic storage with adjustable screw reclaimer.
Fuel Storage
5. Receiving


TYRANNOSAURUS® Step Feeder works together with the Shredder intelligently. Step Feeder works as both feeder and buffer - therefore it can feed TYRANNOSAURUS® Shredder optimal amount of waste to maximise capacity and shredding result.

6. Organics separation

Organics separation

Wet organic content would decrease the fuel quality. In order to ensure high calorific value the wet organics are separated with Drum Screen from the material after pre-shredding. 

7. Screening


To assure purity of the fuel it must be screened. First magnet separates ferrous metals from the material. After the magnet, incombustible fines are screened with TYRANNOSAURUS® Fines Screen. Aluminium and other non-ferrous metals are separated with Eddy Current Separator. TYRANNOSAURUS® Air Classifier finalizes the screening process by separating heavy inert material into two or three fractions. 

8. Fine shredding

Fine Shredding

The fuel must burn rapidly in the cement kiln and small particle size increases the flammability of the fuel. TYRANNOSAURUS® Fine Shredder can reduce the particle size of the fuel to 20-25 mm, which makes sure that the fuel is fully prepared for maximum combustion result in the burner.

9. Storages


The storage systems of BMH Technology are not designed only for storing, but also to homogenize the fuel to ensure uniform quality. Storage system consists of silo distributors, silos and TYRANNOSAURUS® Screw Reclaimers and all equipment work ​together to avoid clogging and enabling required fuel reclaiming.

10. Conveying


The location and sites of cement kilns vary and therefore compact and reliable transportation solutions are needed. Belt Conveyors and Tubular Belt Conveyors are used in the process to fit the layout and conveying needs of each plant. Bucker Elevators are available for vertical transportation. Each conveying solution is designed for safe and dust free material transportation.

11. Feeding and dosing

Feeding and dosing

Undisturbed and controlled flow of fuel is enabled by suitable dosing and feeding systems. BMH Technology offers both, pneumatic and mechanical solutions. The pneumatic feeding system includes a dosing hopper with accurate flow control. The fuel is fed into a Rotary Valve Feeder from where it is injected to into the pneumatic system and further into the burning process. The mechanical system includes receiving bunkers, silos, dosing and flow monitoring designed for wide range of alternative fuels.
