Process overview

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

1. Feeding
1. Feeding
The TYRANNOSAURUS® process starts with the step feeder. Its moving floor continuously feeds an optimum amount of waste into the process while it communicates with the TYRANNOSAURUS® shredder. Once fully loaded it keeps the process automatically well fed, while the operator can focus on other tasks.
2. Pre-Shredding
2. Pre-Shredding
Pre-shredding is a solution for low quality waste. TYRANNOSAURUS® Pre-shredders are an ideal solution for rough shredding. They are especially designed to open plastic bags, to prepare waste for organics separation and to increase the capacity of the entire process.
3. Organics Separation
3. Organics Separation
Wet organic content would decrease the fuel quality. In order to ensure high calorific value the wet organics are separated from the material after pre-shredding with a specific screen.
4. Shredding
4. Shredding
The heart of the process is the main shredder. The TYRANNOSAURUS® Shredder cuts almost any solid waste to a size of a business card in one pass. Difficult materials such as carpets, plastic films and foils or tyres are no challenge to the shredder. It is able to process as much as 50 tons of waste per hour to 80 mm particle size. It is the most robust shredder of its kind and has patented features without comparison.

The Massive Impact Protection System (MIPS®) protects the shredder against any major damage caused by unshreddable items. The ZeroGap® technology ensures an optimal cutting profile even with worn knives. It is a semi-automatic system hydraulically maintaining the cutting gap in zero. As an outcome of these features, high capacity, low operational cost and the highest availability in the market are guaranteed.
5. Conveying
5. Conveying
The location and sites of cement kilns vary and therefore compact and reliable transportation solutions are needed. Belt Conveyors and Chain 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.
6. Screening
6. Screening
To assure the purity of the fuel, it needs to be screened. First a 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 larger inert particles such as pieces of brick, stones, residual metals and other heavy three-dimensional particles. This guarantees high quality fuel production.
7. Fine Shredding
7. 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 down to 20-25 mm, which makes sure that the fuel is fully prepared for maximum combustion result in the burner.
8. Fuel Storage
8. Fuel Storage
The storage systems of BMH Technology are designed not only for storing, but also for homogenizing the fuel to ensure uniform quality. The storage system consists of silo distributor, silos and TYRANNOSAURUS® Screw Reclaimers. All equipment work together to avoid clogging and to enable required fuel reclaiming.

The silo storage is an enclosed dust-free, first in - first out automatic storage with adjustable screw reclaimer.
Fuel Storage
9. Feeding and dosing
9. 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.

Key equipment
