Lindner Komet 2200HP: High-Performance Secondary Shredding for SRF

When a waste processing operation needs to produce a consistent, high-quality Solid Recovered Fuel (SRF), the performance of the secondary shredder can have a major impact on the final product.

For Shanks Waste Management at its Locharmoss site in Dumfries, Scotland, replacing an established Lindner Komet 2200 with a Lindner Komet 2200HP delivered increased throughput, improved particle quality and greater flexibility across the operation.

The original Komet 2200 had already demonstrated impressive longevity, operating for approximately 37,000 hours over 10 years with 30mm screens and producing high-quality SRF without major mechanical issues.

When the machine reached the end of its planned lifecycle, Shanks chose to replace it with the higher-performance Komet 2200HP.

The results exceeded expectations.

A Proven Komet 2200 Replacement

Shanks Waste Management had already been using a Lindner Komet 2200 at its Locharmoss facility.

The machine had been operating for approximately:

37,000 hours

over a period of around 10 years.

During this time, it was producing high-quality SRF using 30mm screens and had experienced no major mechanical issues.

That’s an important part of this case study.

The decision to move to the Komet 2200HP wasn’t driven by a failure of the existing technology.

Instead, the original machine was being replaced as part of a planned lifecycle project.

This gave Shanks the opportunity to upgrade its secondary shredding performance rather than simply replace like-for-like.

---

Why Upgrade to the Komet 2200HP?

The main reason for choosing the Lindner Komet 2200HP was increased performance.

The Komet HP is designed with additional cutter rows compared with the standard Komet, increasing the number of cutting actions available during operation.

Lindner’s Komet HP documentation describes the machine as delivering up to 60% higher output than the standard Komet series, with two additional cutter rows.

The HP configuration is therefore particularly suited to applications where the operator needs more throughput without compromising the quality of the finished material.

For Shanks, the upgrade delivered exactly that.

---

Producing High-Quality -30mm SRF

One of the most important requirements at the Locharmoss site was producing high-quality Solid Recovered Fuel.

SRF requires controlled material sizing and consistent processing to meet the requirements of downstream users.

The Komet 2200HP was configured with the cutting technology required to produce a fraction well below 30mm.

Shanks reported that the new machine exceeded expectations in terms of throughput while producing high-quality SRF with a particle size significantly below the 30mm target.

This combination of throughput and particle quality is one of the key benefits of using a dedicated secondary shredder for SRF production.

---

Seven Rows of Cutters

One of the defining features of the Komet 2200HP is its high-performance cutting system.

The HP model uses seven rows of cutters, compared with the standard Komet configuration.

Lindner states that the seven-row configuration enables more than 5,000 cuts per minute.

The additional cutting actions help the machine process material efficiently while maintaining the controlled particle size required for applications such as SRF production.

---

High-Performance Belt Drive

The Komet HP uses a high-performance gearless belt drive system.

The system combines high-performance ABB motors with precise electronic control to deliver the power required for demanding secondary shredding applications.

The belt-drive design also helps keep the machine mechanically straightforward.

Benefits include:

• Efficient power transmission
• Robust operation
• Reduced mechanical complexity
• Lower maintenance requirements
• Readily available standard components

This focus on reliability is particularly important for plants where the shredder operates for long production periods.

---

Internal Pusher System

The Komet’s internal pusher system provides controlled feeding of material into the cutting chamber.

Because the pusher is integrated within the machine, material can be fed smoothly and consistently towards the rotor.

Lindner describes the system as providing continuous shredding through smooth feeding, while eliminating external guide elements that can create additional wear points.

Consistent feeding is essential to maintaining stable throughput and preventing unnecessary interruptions.

---

Controlled Particle Size

Producing SRF isn’t simply about shredding material as quickly as possible.

The final particle size matters.

The Lindner Komet 2200HP incorporates a high-precision shear cutting system with an adjustable cutting gap.

This allows the cutting system to be fine-tuned according to the material and desired output.

The machine also uses interchangeable screen units with different mesh sizes, allowing operators to adjust the final output specification.

For SRF producers, this provides greater control over the finished fuel.

---

Plug & Go Screen System

The Komet HP features a hydraulically operated, swivel-mounted screen unit.

This makes screen changes and maintenance access considerably easier.

Different screen apertures can be used to help achieve the required output particle size.

The system is designed so that screen changes can be carried out efficiently, reducing unnecessary maintenance downtime.

For high-volume waste processing facilities, reducing the time required for maintenance can make a significant difference to overall machine availability.

---

Protecting the Shredder from Contaminants

Waste streams can contain unexpected materials that aren’t suitable for the cutting system.

The Komet HP incorporates a torque-limiting safety clutch designed to protect the drive system when blockages or foreign objects cause excessive loads.

The system can rapidly disengage the drive and bring the machine to a controlled stop.

This helps protect critical components and reduce the risk of costly damage.

---

21-Day Installation Project

Installing a new secondary shredder into an existing waste processing plant isn’t always straightforward.

The Komet 2200HP had a different footprint to the previous Komet 2200, which meant modifications were required to accommodate the new machine.

Mach Tech worked with the project team and main contractor through the planning process.

The shredder was also lowered by approximately 1,100mm as part of the project to make future maintenance easier.

The complete removal and installation process took approximately:

21 days

from start to finish.

This highlights the importance of experienced installation and engineering support when upgrading industrial shredding equipment within an existing plant.

---

Commissioning the Komet 2200HP

Once installed, the machine was commissioned by Mach Tech Services.

The customer reported that the Komet 2200HP ran trouble-free after commissioning.

The additional two rows of rotor knives also contributed to the improved SRF quality required by Shanks’ customers.

Correct commissioning is an important stage of any new shredder installation.

A machine needs to be configured around:

• Feedstock
• Throughput
• Output requirements
• Screen specification
• Cutting gap
• Downstream equipment

Getting these settings right from the beginning can help maximise machine performance.

---

Increased Throughput Created More Production Flexibility

One of the biggest benefits of the Komet 2200HP installation was increased throughput.

The additional production capacity meant Shanks could make up processing time more effectively.

This had a direct impact on maintenance planning.

The increased throughput allowed the plant to:

Carry out planned maintenance
The additional production capacity created enough spare time to shut the plant down for planned maintenance without falling behind on customer requirements.

Reduce weekend shifts
The increased throughput also meant the site no longer needed to run additional weekend shifts simply to meet customer demand.

This is an important reminder that shredder performance isn’t just about tonnes per hour.

Higher throughput can create operational flexibility across an entire plant.

---

Planned Maintenance Instead of Reactive Maintenance

One of the most effective ways to improve shredder reliability is to move away from reactive maintenance.

Reactive maintenance happens when something fails.

Planned maintenance allows operators to schedule inspections, wear-part replacement and repairs around production requirements.

The increased throughput delivered by the Komet 2200HP gave Shanks more flexibility to carry out planned maintenance while still meeting customer demand.

This can help reduce:

• Unplanned downtime
• Emergency repair costs
• Production disruption
• Overtime
• Missed customer commitments

---

Mach Tech’s Service & Spares Package

The Komet 2200HP installation was supported by a service and spares package developed by Mach Tech.

The first inspection was completed as part of the package, while wear parts were supplied throughout the year at an agreed discounted rate.

The package included components such as:

• Knives
• Screens
• Seals
• Other wear components

This helped ensure the site had access to the parts required to keep the shredder operating reliably.

---

Why Genuine Shredder Parts Matter

Secondary shredders operate under demanding conditions.

Cutting components and screens are exposed to significant wear, particularly when processing mixed waste.

Using the correct replacement components can help maintain:

• Cutting performance
• Particle consistency
• Throughput
• Energy efficiency
• Machine reliability

Mach Tech also maintains over £1 million worth of spare and wear parts in stock, helping customers access components quickly when they are required.

Many parts can be dispatched the same day, helping reduce unnecessary downtime.

The Komet 2200HP for SRF Production

The Lindner Komet 2200HP is particularly well suited to applications where consistent, high-quality alternative fuel is required.

A typical SRF processing system may involve:

Waste Reception → Primary Shredding → Separation → Secondary Shredding → Screening → SRF

The secondary shredder is responsible for producing the controlled final fraction required by the fuel specification.

The Komet HP’s combination of high throughput, precision cutting and adjustable screens makes it a strong option for this stage of the process.

Mach Tech has extensive experience supplying Komet shredders for SRF applications across the UK.

---

SRF vs RDF

The terms SRF and RDF are often used interchangeably, but they are not exactly the same.

Refuse Derived Fuel (RDF) generally refers to fuel produced from waste after processing and preparation.

Solid Recovered Fuel (SRF) is produced to a more defined specification, with characteristics such as particle size, calorific value and contaminant levels controlled according to the intended application and relevant standards.

This means the shredding process becomes particularly important when producing a consistent SRF product.

---
