MK3 Tyre Baler: Container Optimisation and Advanced Processing

By:     Kieran Donnelly

Expert review by:     Conor Murphy

The MK3 Tyre Baler was developed for operations that can no longer afford inefficiency at the processing or dispatch stage. Tyre recycling facilities face real pressure to do more with the same resource base; processing volumes are rising, export logistics are growing more complex, and every hour spent on container loading is an hour not spent on throughput. Gradeall International designed the MK3 in direct response to these pressures, addressing the operational bottlenecks that high-volume recyclers and export-oriented facilities encounter most consistently.

The MK3 Tyre Baler builds on the proven foundation of the MKII whilst delivering measurable improvements in three areas: per-bale processing capacity, container loading efficiency, and structural durability under increased compression loads. This article covers what those improvements mean in practice, how the MK3 differs from its predecessor, and which operations are best placed to benefit.

Container Loading: From Bottleneck to Streamlined Operation

For operations exporting processed tyre bales, container loading has historically been one of the most labour-intensive stages of the workflow. Standard PAS 108-compliant bales, whilst meeting specification, were not dimensioned with container utilisation as a primary engineering consideration. Loading times often exceeded one hour per 40-foot container, with significant positioning effort required to achieve acceptable space utilisation.

This bottleneck had a compounding effect. Delays at the loading stage created knock-on inefficiencies in scheduling, labour allocation, and transport cost per tonne.

How the MK3 Solves the Problem

The MK3’s container-optimised compression system produces bales specifically dimensioned for efficient loading into standard 40-foot shipping containers. Standard loading with conventional PAS 108 bales typically achieves 18 to 20 bales per container. The MK3 achieves 20 to 22 bales per container whilst cutting loading time from over 60 minutes to approximately 20 minutes.

That 40-minute reduction per container is not a marginal improvement. For operations loading several containers per week, it translates directly into reduced labour costs and more predictable scheduling.

The MK3 applies 75 tonnes of hydraulic pressure to achieve this bale specification, meaningfully higher than standard baling equipment. The increased compression force required a full structural review, covering the compression chamber, hydraulic ratings, and wire binding systems, to ensure enhanced performance did not introduce reliability risks.

Processing Capacity: The 27% Increase

The MK3 processes up to 140 tyres per bale, compared to the MKII’s 110-tyre capacity. That 27% increase changes the arithmetic of running a processing facility.

Fewer bales per tonne of processed material means fewer handling cycles, reduced wire consumption per tonne, less storage space required for finished bales, and lower transportation cost per tonne exported. Each saving accumulates across every day of operation.

Hydraulic and Cycle Time Improvements

The increase in compression force required comprehensive improvements to the hydraulic system. The MK3 incorporates advanced pressure control and flow management that optimises compression cycles, protect equipment from overload, and reduces non-productive time between cycles.

These improvements may appear modest individually, but they accumulate significantly across extended processing sessions. A facility handling several hundred tyres per day will see the benefit of reduced cycle times consistently, shift after shift.

Single-operator capability is retained throughout. Enhanced capacity does not mean increased complexity. Operators familiar with the MKII will find the transition straightforward, with training focused on updated procedures rather than a fundamentally different operational model.

Structural Engineering for 75-Tonne Operation

Increasing the compression force to 75 tonnes cannot be accommodated by simply upgrading hydraulic components. The entire structural envelope requires analysis and reinforcement to distribute increased loads safely and maintain reliability across the equipment’s service life.

Gradeall’s in-house engineering team applied Finite Element Analysis to the MK3’s structural design, identifying stress concentration points and optimising material distribution. The result is a structure that handles enhanced operational loads reliably without unnecessary complexity or cost.

Bale Consistency and Quality

The combination of higher compression force and more precise hydraulic control produces bales with more consistent characteristics. Bale density, dimensions, and stability are more uniform from cycle to cycle.

Consistent bale characteristics simplify logistics planning and customer specification compliance. For operations supplying bales to end-users with specific material requirements, output consistency is a commercial advantage, not merely an operational convenience.

Which Operations Benefit Most

The MK3’s advantages, principally container optimisation and enhanced per-bale capacity, are most valuable to a defined set of operational profiles.

Export-oriented operations are the primary beneficiaries. If a facility regularly loads bales into shipping containers, the reduction in loading time and improvement in container utilisation create immediate, recurring cost savings. The economic case over a standard baler is clearest here.

High-volume regional processors benefit from the increase in per-bale capacity. For facilities that have reached the limits of their current baler without wanting to add a second machine, the MK3 offers a route to increased output from the same footprint.

Operations planning to expand volumes or enter export markets for the first time will find the MK3’s capacity headroom appropriate. Investing in equipment sized precisely for current needs, without allowance for growth, frequently results in a second capital investment within a few years.

For operations processing truck tyres or OTR tyres, pre-processing with a truck tyre sidewall cutter upstream of the baling stage improves material consolidation and supports PAS 108 compliance. The MK3 accommodates pre-processed material efficiently.

“The MK3 addresses real operational challenges that our customers face daily,” notes Conor Murphy, Director at Gradeall International. “It’s not just about processing more tyres. It’s about enabling efficient, profitable operations that support sustainable business growth whilst maintaining our commitment to reliability and operational simplicity.”

Installation and Gradeall Support

Installing the MK3 requires attention to foundation specifications that reflect the increased compression forces involved. A professional assessment of the installation site is recommended before equipment arrives, as standard baler foundations may not be adequate for a 75-tonne operation.

Gradeall provides comprehensive installation services covering commissioning, operator training, and performance verification. The equipment is designed and manufactured at Gradeall’s facility in Dungannon, Northern Ireland, where the company has been producing tyre recycling equipment for nearly 40 years. Equipment from the tyre recycling range has been exported to more than 100 countries, and the MK3’s design draws directly on operational feedback from that global install base.

Post-installation support includes OEM spare parts, a global service engineer network, and the option for prospective buyers to visit the Dungannon facility for a live equipment demonstration before purchase.
