Pre-Crusher: The Critical Pre-Treatment Step for Enhancing Production Line Efficiency and Throughput
In waste treatment plants, RDF/SRF production facilities, and waste-to-energy operations, the pre-treatment stage plays a decisive role in determining the overall performance of the processing line. Efficient size reduction of incoming materials not only optimizes downstream sorting, conveying, and processing operations, but also helps increase throughput while reducing overall operating costs.
Designed to meet the processing demands of mixed waste streams with complex compositions, the BMH Technology TYRANNOSAURUS 6600 Pre-Crusher delivers powerful pre-shredding performance, producing a consistent and uniform material size. As a reliable pre-treatment solution, it helps businesses establish an efficient operational foundation for modern waste management systems.
Tailored-designed for processing unsorted waste
TYRANNOSAURUS® 6600 pre-crusher is a low-speed, dual-shaft primary shredder designed for the industrial-scale processing of unsorted municipal solid waste (MSW). The machine is commonly used as a bag opener at the first stage of waste treatment lines. The primary shredding process is intended to prepare waste materials for subsequent processing stages. Therefore, integrating the TYRANNOSAURUS® 6600 pre-crusher into waste refining and sorting operations enhances separation efficiency, improves material recovery and classification, and enables downstream processes to achieve optimal performance.

01
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
Outstanding Technical Advantages of the Hydraulic Drive System:
High Torque & Powerful Shredding Performance:
Delivers exceptional shredding force across the low-speed range, allowing the machine to easily handle large, tough, and high-density waste materials.
Anti-Jamming & Automatic Protection:
Instant rotor reversal is activated when overloads or uncrushable objects are detected. Together with impact load dampening, the system ensures maximum protection of the machine structure and minimizes the risk of damage.
Infinitely Variable Speed Control:
Rotor speed is automatically regulated based on material properties and processing load, ensuring optimal performance, improved throughput, and enhanced energy efficiency.
Durable Construction & Lower Lifecycle Costs:
The elimination of wear-prone mechanical drive components, including gearboxes and couplings, significantly reduces breakdown risks, extends equipment lifespan, and minimizes maintenance expenses.
02
High Torque Enabled by Direct Hydraulic Drive
The TYRANNOSAURUS® 6600 Pre-Crusher is equipped with a direct hydraulic drive system that delivers high torque, enabling efficient processing and shredding of heterogeneous input materials with varying compositions.
TYRANNOSAURUS® 6600 is a high-capacity shredder (220 – 320 kW), capable of performing a large number of shredding cycles to achieve high throughput and processing efficiency.
During normal operation, the machine maintains a substantial power reserve, allowing it to handle difficult-to-shred materials and fluctuations in waste composition with ease, ensuring stable and continuous performance.
03
Optimized Crushing Geometry
Knife geometry is a key factor in generating capacity. BMH Technology have optimized the 6600 pre-crusher’s knives from several aspects. 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.

An Efficient Bag Opener for Unsorted MSW
The Tyrannosaurus® 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 direct hydraulic drive and optimized crushing geometry.
The Tyrannosaurus® 6600 pre-crusher has a large feed hopper that enables different loading options and crushing of large objects. It reduces the particle size down to 100 – 300 mm.
