Tandem Mixer technology:

HF takes it to the next level

HF Mixing Group is supplying Tandem Mixers for more than 15 years and has kicked off a revolution in mixing since then. The concept appears to be simple, but all those years of experience have shown that the highest degree of machine engineering has to be combined with extensive process know how to make a Tandem Mixer successful. And a mixing line is only successful if the calculated output and productivity is achieved – combined with a reliability which enables stable production for years.

As matter of fact to develop the process to mix on a Tandem Mixer takes some time and efforts – not to forget the technological know-how of the mixing process itself. HF offers the possibility to accompany this development by offering extensive trials and engineering studies – to shorten the time from ordering a machine up to the point of running in full production.

The goal of a Tandem Mixer is to reduce the specific cost of mixing a compound – on many occasions, HF has proven that overall cost reductions of 15% can be achieved compared to standard lines with a single mixer. This, in between other, is achieved by reducing the mixing steps for a PCR compound from 2,5 to 1,5 steps.

But productivity is not the only driving factor to invest in a Tandem Line – the quality of the compound overall and specifically constant and repeatable mixing of modern compounds is to be ensured. To optimise dispersion, distribution, temperature control and process stability makes a significant difference in today’s production of more complex compound recipes. The intermeshing mixers produced by HF and used in a Tandem Line guarantee to meet these requirements more than any other mixers on the market.

Experiences have shown that no compromise on quality can be made – and HF is supporting this approach with delivering a control system for Tandem Lines which enables their customers to not only run the machine efficiently but also uses online condition monitoring to always reflect on a reliable compound quality which is repeatable.

HF emphasises on result driven production concepts for its customers – further innovations in terms of integrating industry 4.0 solutions to the mixing process are on its way and the focus is clear: Intelligent machines will integrate new digital solutions into the mixing process and will ensure to meet the expectations of the future.

Brownfield projects

The COVID pandemic put a stronger focus on replacing existing machines instead of adding new capacities to a production plant. Also, productivity as well as sustainability aspects are driving many tyre companies to have a closer look to the installed base.

But inspecting a mixing line which has run for more than 15 years (or sometimes even 25 years) brings to light what challenges may come up if this line will be replaced by a new one. Output values need to be increased, a new mixer technology should improve the quality of compounds, modern automation solutions should support the daily production procedures and increase process stability – many more requirements should be met. One of the largest challenges is limited space when looking at an upgrade of machinery.

Not only the pure space but also intralogistics within a mixing line can create headache – from upstream equipment feeding a mixer all the way to downstream machinery processing the batch further – many modern solutions can be used today but looking at the available space installing them is the challenge.

With a clear focus on such brownfield projects, HF has managed several conversions from old to new with unmatched success. A key in such projects is the planning and pre-engineering process. Starting with an inspection of not only the mixer but all surrounding factors in the building – considering also the material flow – and then continuing with a 3D- scan of the existing equipment including pipe and cabling routing the basis for planning can be laid. Supported by this 3D-scan HF engineers plan and design with 3D models the complete mixing mill room.

By keeping the existing machinery as the base layer and inserting new equipment in an over-lay collisions of steel constructions, limitations in space and optimised pipe and cable routing can be identified. Furthermore, an improved process flow chart is the basis of planning material flow, work processes and even manpower to operate the new mixing line. Finally, new controls and automation solutions – on the basis of industry 4.0 – will improve operating and monitoring the equipment.

One of the largest benefits using HF’s Pre-Engineering is shortening the planning and execution time – and last but not least the reduction of financial funds is possible by starting up the new line much quicker compared to the conversion of lines in earlier years.

Safety first

Supporting all major tyre manufacturers with mixing technology HF constantly strives for improving operational procedures in the mixing mill room. When it came apparent that the variety of compounds increased more and more – driven by many more types and technologies in tyres today – the changeover times from one recipe to the other was put in the focus of operational optimisation. Not only flexible automation solutions are required but also quick availability of the mechanical equipment after the last batch of the current recipe was dispatched. In between other HF identified the cleaning of the mixing chamber as a critical action during changeover in two aspects: First it needs to be safe for the maintenance personal to enter the mixing chamber and secondly time can be saved if the access to the chamber can be optimized.

In order to meet both requirements HF’s engineers designed a maintenance box, the so-called mBox©, which is mechanically integrated directly underneath the mixer – combining the mixer with the chute of a dump extruder for example.

In the moment the mixing line is switched to cleaning mode and all movements of parts are blocked a moveable platform – the floor of the maintenance box – is inserted horizontally underneath the mixer. A door of the box can be opened, and maintenance personnel can enter the box safe and secure, standing underneath the mixer with easy access to the mixing chamber.

Besides the safe working environment customers from HF have noticed saving time and having the opportunity of even inspecting the mixing chamber easier and more frequent during a changeover.

Especially in new installations of a mixing line the mBox© can be integrated in the design of the line easily and right from the start – benefitting the safety and operation of the line daily.

HF Screw Presses

The production of screw presses is one of HF`s core competences for decades. The screw press has gained recognition during its affiliation with KRUPP. Thus, the presses operate all over the world and more than 2.500 presses are installed in various industries for example the edible oil industry, biomass technology and rendering. And, most interesting for the tyre industry, the presses accomplish benchmarking results in the dewatering of natural and synthetic caoutchouc. As a more efficient and space saving solution instead of band dryer systems or similar the screw press has its strong eligibility in dewatering process.

HF Curemaster

HF brought the first hydraulic column type curing press to the tyre industry in 1997. Since then, it continued to develop this product to meet the demanding requirements of its customers.

The HF Curemaster was launched two years ago and since then the patented truck tyre curing press has been successfully installed in multiple locations and in efficient operation. The press provides a flexible and compact footprint, making it possible to replace older presses with potentially more presses per existing trench.

The HF Curemaster also focuses on optimising energy efficiency to ensure the lowest total cost of ownership in the curing plant. The HF Curemaster´s hood design incorporates insulation inside the hood to provides the best insulation effect. In addition, the HF Curemaster provides an extremely fast cycle time to minimise the overall amount of heat loss during the open and close sequence of the press.

HF PCR Design

Delivering for a new greenfield plant is relatively straightforward. However, HF understands the important need of the replacement market as well. It is important to be flexible to meet all the varying trench layouts (pit, shelf, pitless, and so on). Equally important is the need to be able to replace existing 42” – 45” old mechanical presses with 48” – 52” modern presses in order to meet the growing demand for larger tyre sizes.

All replacement projects are analysed carefully together with customers. Attention is paid closely to all details related to operation, maintenance access, mould & bladder change requirements as well as all local safety regulations. HF´s long experience with curing presses provides a large variety of modular options to be used for finding the optimised fit for each specific request.

HF Stack Passenger Car Inflator (PCI)

The requirement for post cured tyres continues to grow in the market and HF has designed a simple and compact solution that can be incorporated in all HF presses as well as behind most all existing older presses.

The patented HF Stack PCI design allows for the PCI to be integrated into even the tightest footprints. This solution eliminates any movement or rotations of the PCI body itself and greatly reduces the amount of moving mechanical components and maintenance.

HF Digitalisation

HF recognises the important trend of digitalisation for the tyre manufacturers and has developed reliable, customised software solutions for machine data communication between machine control and customer IT systems. The main steps were to focus on MES, SCADA and Recipe Management interfaces.

HF Smart Curing enables customers to get started quickly and effectively with a future-oriented digitisation solution. The main advantage in this case is that software for machine data acquisition is supplied directly by the supplier and not by IT service providers.

OPC server technology and efficient network solutions are tailored to the machine enable secure data acquisition. This software can provide feedback in regard to condition monitoring, diagnostic function, machine services, energy monitoring and remote service.

The benefit of connecting your equipment with digitalised solutions clearly accelerates a target-oriented development and improves the Total Cost of Ownership of the equipment.

The Alliance for the Future of Tires (AZuR) is preparing a major presence at THE TIRE COLOGNE 2026, the world’s leading tyre industry trade fair running from 9 to 11 June 2026. Building on its successful collaborative model, AZuR will return with an even larger network of partners representing all facets of the sustainable tyre circular economy. At the joint exhibition stand located in Hall 7.1, nineteen AZuR members from across the tyre and recycling sectors will showcase their work while the alliance takes on an intensive role within the fair’s event programme.

By bringing together industry, small businesses, trade and recycling specialists once again, AZuR demonstrates the full circular value chain under one roof. Visitors to the stand can explore sustainable new tyre production alongside repair, retreading, and both mechanical and chemical recycling processes.

The 2026 fair will place a special emphasis on promoting tyre retreading as a proven method to save resources, slash CO₂ emissions and reduce costs through multiple reuse of quality casings. To help retreading gain wider traction, AZuR is inviting European retreaders to attend and is integrating the topic into dedicated events and new dialogue formats spanning the entire value chain.

Among the fresh initiatives is a municipal dialogue connecting city decision-makers with experts to showcase retreaded tyres for public fleets, waste management and transit systems, highlighting CO₂ savings and up to 30 percent lower operating costs. An educational project called Retreading Goes to School will train tyre dealers, auto shops and their staff on the safety, quality and economic benefits of this technology.

THE TIRE COLOGNE 2026 thus offers AZuR and its partners an unmatched platform for presenting innovations, best practices and concrete solutions. The joint stand will also serve as a meeting hub for policymakers, scientists and business leaders to discuss advancing retreading, new uses for recycled materials, chemical recycling progress like pyrolysis and better political frameworks.

AZuR network coordinator Anna-Maria Guth said, “Our joint stand demonstrates the strength of the industry when it works together on solutions. The increasing number of partners participating confirms our approach and the relevance of the tyre circular economy.”

Tyrecycle, led by CEO Jim Fairweather, has responded to a recent federal inquiry into end-of-life tyres, conducted by the House of Representatives Standing Committee on Industry, Innovation and Science, by stressing that the industry’s successes should not hide its failures. While the inquiry focused on commercial and economic aspects of tyre recycling, Fairweather argued that any regulatory changes must target specific market gaps rather than burdening parts of the sector that already work well. Tyrecycle supports mandatory market-based regulation and increased government procurement, and Fairweather described illegal tyre dumping as completely unacceptable.

The recovery rate for passenger and truck tyres in Australia stands at 96 percent, yet off the road tyres, or OTRs, tell a different story. Only two percent of OTRs are recovered, despite these large tyres from mining and agriculture accounting for about 29 percent of Australia’s tyre market. Fairweather highlighted regional disparities, noting Western Australia produces 60,000 of OTRs out of a national total of 155,000 tonnes, while Queensland and New South Wales together contribute another 75,000 tonnes. He warned that a complete system overhaul could raise consumer prices with little benefit.

Fairweather explained that passenger and truck tyres benefit from established state-based regulations and infrastructure, but OTRs require targeted intervention. Policy must differentiate between working markets and those needing genuine help. Fairweather reiterated that Tyrecycle is prepared to process every tyre in Australia, provided the correct supporting system is in place.

A critical shortage of domestic end markets for recycled tyre materials is a central problem. Tyrecycle collects around ninety thousand tyres daily, yet viable markets remain limited. Fairweather cautioned against over reliance on extended producer responsibility schemes, arguing they do not inherently create market demand. Australia needs market-based solutions that enable recyclers to find commercially viable applications. Tyre derived fuel provides an outlet, but more recycled products should be used domestically rather than exported. Other applications face limited demand, and collection alone does not close the waste loop.

On illegal dumping, Fairweather argued that schemes funnelling money through a central authority risk inflation and reduced competition. Better alternatives include rigorous enforcement of accreditation and monitoring systems that maintain direct customer relationships. He supported a mandatory scheme requiring manufacturers to contribute to waste management costs, though he prefers a market-based approach over a strict extended producer responsibility framework.

Fairweather stated that existing state-based regulations are sufficient; no new laws are needed, only proper enforcement. Where enforcement is weak, non-compliant operators undercut legitimate recyclers, reducing investment confidence. High quality enforcement supports market integrity, competition, lower prices and greater consumer choice. He placed tyre issues in the context of end-of-life vehicles, noting Australia processes 850,000 vehicles annually, generating 1.36 million tonnes of waste.

Fairweather concluded that only a combination of effective regulation, infrastructure investment and genuine end market development can achieve a circular economy for tyres. Without these measures, even well-intentioned schemes cannot deliver sustainable outcomes. Tyrecycle supports stronger compliance, expanded domestic consumption of recycled products and targeted fixes for off the road tyres, with Fairweather simply wanting the right regulation properly enforced.
