The Lindner Micromat 1500: Next-Generation Plastic Recycling Technology

The plastics recycling industry is constantly evolving.

As recyclers face increasing demands for higher throughput, improved efficiency and greater flexibility, shredding technology needs to evolve with it.

That’s exactly what Lindner set out to achieve with the Lindner Micromat 1500.

Introduced at K 2019, the next generation of the Micromat series brought together a new entry-level machine size, an innovative Multiplex cutting system, redesigned controls and new software capabilities.

The result is a highly adaptable plastic recycling shredder designed to process a wide range of plastic materials efficiently and consistently.

Introducing the Lindner Micromat 1500

The Micromat has been developed using Lindner’s established shredding technology, but the latest generation introduced a number of important improvements.

The Micromat 1500 gets its name from its 1,500 mm rotor length, making it the entry-level model in the Micromat range at the time of its introduction.

However, entry-level doesn’t mean basic.

The machine was developed to provide recyclers with a flexible and efficient solution for processing different types of plastic.

Its biggest technological development was the introduction of the new Multiplex cutting system.

The new Multiplex cutting system

One of the standout features of the Lindner Micromat 1500 is its Multiplex rotor and cutting system.

Traditional shredding systems can be limited by the way material is presented to the cutting tools.

Lindner approached the problem differently.

The Multiplex system uses a three-dimensional arrangement of rotor knives, designed to actively pull plastic material into the cutting chamber.

This creates a more aggressive and efficient cutting action.

According to Lindner’s development testing, the system can increase throughput by approximately 40% on average compared with previous technologies, with some materials delivering even greater increases.

For a plastics recycling operation, that can make a significant difference.

More material processed per hour can mean:

• Increased production capacity
• Better utilisation of downstream equipment
• Improved plant efficiency
• Potentially lower processing costs per tonne
• Greater overall productivity

Actual throughput will depend on the material, configuration, screen, feed method and required output size.

Designed to process a wide range of plastics

Plastic waste isn’t one uniform material.

A recycling facility may handle:

• Plastic packaging
• Film
• Rigid plastics
• Production waste
• Industrial plastics
• Mixed plastic waste
• Post-consumer plastics
• Post-industrial plastics

Each material can behave differently during shredding.

Some plastics are rigid and brittle.

Others are flexible, lightweight or difficult to feed.

The Multiplex cutting system was developed specifically to provide greater flexibility across different types of plastic.

During development, Lindner tested the cutting system with customers across a wide range of plastic materials before optimising the geometry of the rotor knives.

Why throughput matters in plastics recycling

For a recycling business, throughput is one of the most important performance measurements.

The more material that can be processed effectively, the greater the potential production capacity.

But throughput shouldn’t be considered in isolation.

A high-performing plastic shredder also needs to deliver:

• Consistent output
• Reliable operation
• Controlled particle size
• Efficient energy use
• Manageable wear
• Straightforward maintenance

The Micromat 1500 was designed around this combination of performance and flexibility.

New generation controls

The mechanical technology wasn’t the only area Lindner improved.

The software and controls were redeveloped from the ground up for the new generation Micromat.

The machine introduced the Lindner Mobile HMI, providing operators with a touchscreen interface designed around simple and intuitive operation.

The mobile control panel can be positioned at either the front or rear of the shredder depending on what the operator needs to do.

For example, the position can be changed to make tasks such as screen replacement easier.

Simplifying shredder operation

Industrial recycling plants increasingly rely on sophisticated equipment and automation.

However, sophisticated technology doesn’t necessarily need to mean complicated operation.

Lindner’s redesigned HMI was developed with ease of use in mind.

The touchscreen focuses on displaying the functions relevant to the task being performed.

This can make the machine easier for operators to understand while helping simplify everyday operation.

This is particularly relevant as recycling businesses face challenges around recruiting and retaining experienced technical staff.

Intelligent communication with downstream equipment

Another major development was the Micromat’s ability to communicate with equipment further down the recycling process.

The new software allows the shredder to exchange information with downstream machinery.

For example, the Micromat can operate as a dosing unit within the wider processing system.

It can also pass material-quality data to an extruder.

This moves the shredder beyond simply being a size-reduction machine.

Instead, it becomes part of a more integrated recycling process.

The Micromat as part of a complete recycling system

Modern plastics recycling facilities often contain several stages.

Depending on the application, the process could include:

Feeding → Shredding → Sorting → Washing → Separation → Extrusion → Pelletising

The shredder plays an important role at the beginning of this process.

The quality and consistency of the shredded material can influence the performance of downstream equipment.

That’s why selecting the right plastic recycling shredder is about more than simply finding a machine capable of reducing material in size.

It needs to be considered as part of the complete processing system.

Why choose a single-shaft shredder for plastics?

The Lindner Micromat is a single-shaft shredder, making it particularly versatile for recycling applications.

Single-shaft technology provides controlled size reduction through the interaction between the rotor knives and screen.

The screen helps determine the final material size, while the cutting system influences throughput and the way material is processed.

This configuration can be adapted to suit different plastic recycling applications.

The importance of the cutting system

The cutting system is one of the most important components of an industrial shredder.

It directly affects:

• Cutting efficiency
• Throughput
• Output size
• Energy requirements
• Wear rates
• Material feeding

Lindner’s Multiplex system was designed to improve the interaction between the rotor and incoming material.

By arranging the knives three-dimensionally, the system actively pulls material into the cutting chamber rather than relying solely on the material being pushed into the rotor.

This is one of the key technologies behind the Micromat 1500’s performance.

A flexible solution for plastics recycling

One of the biggest challenges facing plastics recyclers is the sheer variety of material they may need to process.

A machine that performs well on one plastic may not necessarily perform as well on another.

The Micromat 1500 was developed to address this challenge.

Its cutting system can be configured around different materials and applications, providing recyclers with a flexible platform rather than a machine designed around a single waste stream.

The evolution of the Lindner Micromat

The Micromat 1500 represents another stage in the development of Lindner’s established Micromat technology.

The fundamental objective remains the same:

Reliable size reduction for demanding recycling applications.

But the technology has continued to evolve.

The introduction of the Multiplex cutting system, redesigned controls and greater connectivity demonstrates how modern shredders are becoming increasingly integrated into automated recycling facilities.

The result is a machine that combines mechanical shredding technology with increasingly sophisticated digital control.

Why invest in modern plastic shredding technology?

As plastic recycling becomes increasingly important, recyclers need machinery that can deliver consistent performance while keeping processing costs under control.

Modern shredders can contribute to this by improving:

• Throughput
• Material consistency
• Automation
• Process control
• Energy efficiency
• Overall plant productivity

The Lindner Micromat 1500 demonstrates how developments in both mechanical engineering and software can combine to improve the recycling process.
