Process overview

TYRANNOSAURUS® Waste Refining Process turns waste in to high quality Solid Recovered Fuel.

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. Shredding
2. Shredding
The next step is to reduce the waste into suitable particle size with the TYRANNOSAURUS® 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 film rolls and foils 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.
3. Separation
After size reduction ferrous and non-ferrous metals, which have material value, are separated from the waste. Magnets and Eddy Current separators are used for sorting out these materials.

Magnet is often the very first separation equipment simply collecting ferrous metals with very strong magnet. Eddy Current uses a strong magnetic field that changes polarity with high frequency to separate non-magnetic metals such as aluminum and copper. After separation, these metals can be further refined into recycled raw materials.

Very fine non-combustible materials such as glass, sand, gravel, soil and organics are also often separated from the waste before moving further into the process. This increases the calorific value of the produced fuel while also removing components that might cause problems during incineration. This separation is done with TYRANNOSAURUS® Fines Screen.

Larger inert particles such as pieces of brick, stones, residual metals and other heavy three-dimensional particles are separated in the end of the process to guarantee high quality fuel production. TYRANNOSAURUS® Air Classifier finalizes the screening process by separating last heavy inert particles from the fuel.
4. Fine Shredding
4. Fine Shredding
The quality of the processed fuel can be further increased by fine shredding. TYRANNOSAURUS® Fine Shredders can reduce the particle size down to 20-25 mm. This increases the combustibility of the fuel especially for cement kilns.

Key equipment



TYRANNOSAURUS® Feeders enable optimal feeding to the shredder/crusher ensuring continuous maximum capacity.

TYRANNOSAURUS® Feeders are an excellent solution for optimizing feeding process to the shredder when continuous flow of material is needed. Feeder works as a buffer and a feeder for the process and lengthens the loading intervals. The feeding capacity of the Feeder is adjusted according to the level of measurement taken from the shredders hopper. TYRANNOSAURUS® Feeders are designed to have high reliability and low maintenance costs, in addition TYRANNOSAURUS® Feeders are easy to install and safe to use.
