HIGH-CAPACITY
PRE-CRUSHING FOR MSW
For Unsorted Municipal Solid Waste
TYRANNOSAURUS® 6600 Pre-Crusher for waste is a slow-rotating, two-rotor crusher designed for industrial scale crushing of unsorted municipal solid waste (MSW). It's often used as a bag opener at the very beginning of the process.
The purpose of pre-crushing is to prepare the waste for further processing, which is why adding a 6600 pre-crusher in a waste refining process improves the waste separation efficiency.

Optimized Crushing Geometry
Knife geometry is a key factor in generating capacity. We have optimized the 6600 Pre-Crusher's knives from several aspects.
Direct Hydraulic Drive
The 6600 Pre-Crusher is powered by a direct hydraulic drive. It provides high torque, which is required to crush heterogeneous feedstock
Main Features and Applications
TYRANNOSAURUS 6600 Pre-Crusher for waste
1
Robust structure specifically designed for heavy-duty use. Works equally well for opening plastic bags before actual shredding or initial size reduction of bulky items.
2
Impressive throughput achieved with simple yet robust construction.
3
Effortless and inexpensive to operate and service.
4
The 6600 series is typically installed in:
- An RDF preparation plant for power boilers
- An SRF preparation plant for cement kilns
- A pre-treatment plant for anaerobic digestion plants
- A pre-treatment plant for waste to chemical plants
- A grate-fired plant as a coarse shredder
An Efficient Bag Opener for Unsorted MSW
The 6600 series pre-crusher for waste is a robust and reliable performer. Despite its simple design, the crusher is equipped with powerful technology, which creates high capacity.
The main contributors for 6600's high performance are the direct hydraulic drive and optimized crushing geometry.
The 6600 pre-crusher has a large feeding hopper that enables different loading options and crushing of large objects. It reduces the particle size down to 100-300 mm.

TYRANNOSAURUS 6600 Pre-Crusher in a waste refining process enables improving the waste separation efficiency.

crushing geometry

Maximized Throughput with Optimized Knife Geometry
Knife geometry is a key factor in generating capacity.
- A large cutting area: two long rotors enable a large number of knives.
- As the knives are positioned in a spiral shape, the power train is loaded evenly, which protects the drive unit.
- Paired knives prevent the material from bending and force it to be cut.
- The knife geometry prevents the particles from sticking to the knives. This generates real throughput as the particles don’t just circle with the rotor.
- The knife dimensions (length/width ratio) are optimized from a performance aspect.
- Exceptionally even particle size (quality) compared to other coarse shredders.

High Torque Enabled by Direct Hydraulic Drive
The 6600 Pre-Crusher is powered by a direct hydraulic drive. It provides high torque, which is required to crush heterogeneous feedstock
- TYRANNOSAURUS 6600 is a high-power (220–320 kW) crusher, which enables a large number of crushing events.
- It also maintains a power reserve in normal operation, which is occasionally needed for managing heterogeneous feedstock.
