Another Successful Lindner Installation

Finding the right shredding equipment can make a significant difference to the efficiency, reliability and quality of a waste processing operation.

For SB Waste, choosing the right technology meant finding a shredding solution capable of handling demanding waste streams while producing a consistent SRF fraction.

Following an on-site demonstration of the Lindner Urraco 75DK mobile shredder, SB Waste selected Mach Tech Services to supply and support its shredding equipment. The company subsequently invested in a fully refurbished Lindner Komet 2200 secondary shredder, creating a two-stage shredding system designed to produce a high-quality, homogeneous SRF output.

A Growing Waste Management Business

SB Waste was established in 1992 by Steve Broadley and has grown from a family business into an established waste management company operating across the UK.

At the time of the original case study, SB Waste operated sites in Cannock, Birmingham and Wolverhampton, employed around 80 people and operated a fleet of approximately 40 trucks. The business also provided nationwide services for specialist hazardous products.

As the company continued to expand its recycling operations, investment in reliable processing equipment became increasingly important.

Choosing the Right Mobile Shredder

Mach Tech Services first became involved with SB Waste when the company was looking for a mobile shredder.

After investigating the market, SB Waste agreed to a demonstration of the Lindner Urraco 75DK.

The machine remained on site for two days, but the response from the operators was immediate.

According to the original case study, staff described the Urraco as:

“The best we’ve had.”

Following the successful demonstration, SB Waste placed an order for the Urraco 75DK.

This is a great example of why on-site shredder demonstrations can be so valuable. Waste streams vary considerably from site to site, and seeing a machine process the actual material provides a much clearer indication of its suitability than simply comparing specifications on paper.

The Lindner Urraco 75DK

The Lindner Urraco 75DK is a mobile twin-shaft shredder designed for demanding waste processing applications.

Its mobile configuration provides flexibility for operators that need to process material in different locations or integrate mobile shredding into an existing recycling operation.

For SB Waste, the Urraco became the primary shredder within its SRF processing system.

The machine was selected because it could provide the robust primary shredding performance required to prepare material for the next stage of processing.

From Primary Shredding to SRF Production

SB Waste had also invested heavily in a complete recycling line supplied by M&K.

The company needed a secondary shredder capable of producing a good-quality homogeneous SRF fraction.

This was where Mach Tech’s experience in SRF production became particularly important.

Rather than simply supplying another machine, Mach Tech could draw on its experience of installing and supporting Lindner technology across the SRF and RDF sector.

The resulting process uses:

Homogeneous SRF Fraction

This two-stage approach allows each shredder to perform a specific role within the overall processing system.

Why Secondary Shredding Matters for SRF

Producing high-quality Solid Recovered Fuel (SRF) requires more than simply reducing waste in size.

The material needs to be processed to achieve a consistent output suitable for its intended end application.

A secondary shredder can help refine the material following primary shredding and downstream separation.

The objective is to produce a more consistent fraction in terms of particle size and composition.

For businesses producing SRF, this can be an important factor when supplying fuel to industrial end users.

The Lindner Komet 2200

Following the successful installation of the Urraco 75DK, SB Waste returned to Mach Tech when it needed a secondary shredder.

The company invested in a fully refurbished Lindner Komet 2200, which was installed to work in line with the Urraco 75DK.

The Komet 2200 provides high-performance secondary shredding for applications where consistent output and high throughput are essential.

Combined with the Urraco 75DK, the system gives SB Waste a dedicated primary and secondary shredding solution.

Lindner Technology for SRF Production

Lindner has a long history of developing shredding technology for RDF and SRF production.

Mach Tech’s experience in this market has allowed the company to support customers looking to improve their fuel production systems and achieve reliable, consistent output.

The original case study stated that Mach Tech had installed equipment capable of processing 778 tonnes per hour of SRF in a one-shift operation, representing approximately 1.5 million tonnes of sub-30mm SRF production.

This experience is particularly valuable when selecting equipment for an SRF application because the shredder needs to be considered as part of the wider processing system.

Why Choose a Two-Stage Shredding System?

Using a primary and secondary shredder provides greater control over the material reduction process.

Primary Shredding

The primary shredder handles the initial reduction of the incoming waste.

The Urraco 75DK is designed to deal with demanding and variable feedstock, preparing the material for downstream processing.

Secondary Shredding

The Komet 2200 then further reduces and refines the material to produce a more consistent output.

This staged approach can provide several benefits:

• Improved control over particle size
• Consistent SRF production
• Better preparation for downstream processes
• High throughput
• Reduced stress on individual machines
• Greater flexibility across different waste streams

Reliability Matters in Waste Processing

For a busy waste management operation, equipment reliability is critical.

Every hour of unplanned downtime can affect:

• Throughput
• Labour utilisation
• Transport schedules
• Customer commitments
• Fuel production
• Overall operating costs

This is why the choice of shredding equipment needs to consider more than initial purchase price.

Reliability, maintenance requirements, spare-parts availability and technical support can all have a significant impact on the long-term cost of ownership.

Customer Confidence in Mach Tech

One of the key reasons SB Waste selected Mach Tech was the company’s experience and approach to the sales process.

Steve Broadley explained that Mach Tech gave the company confidence because the team was prepared to answer difficult questions and demonstrated a strong understanding of its requirements.

He also highlighted the opportunity to visit existing customer sites and speak directly with other operators.

According to the original case study, SB Waste was particularly impressed with the performance of the Lindner machines, their maintenance requirements and fuel consumption, as well as the level of after-sales support provided by Mach Tech.

For Mach Tech, this is exactly what a successful customer relationship should look like.

The job doesn’t finish when the machine is delivered.
