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.

At the Green Week 2026 in Berlin, AZuR network’s partner NEW LIFE reached an audience of 350,000 by showcasing the environmental potential of mechanically recycling tyres into high-quality raw materials and end products. Operating under the banner ‘ZERO WASTE INSTEAD OF ZERO FUTURE’, the group occupied a central position in the newly established ZERO themed area. One of the most engaging exhibits was a large tortoise sculpture from partner KRAIBURG Relastec, crafted entirely from rubber granulate, which captured the imagination of younger attendees and symbolised the creative reuse of materials.

The very floor of the exhibition space demonstrated a practical application, being composed of interlocking tiles made from recycled tyre rubber supplied by MRH Mülsen. Visitors and exhibitors alike noted the comfort and resilience of this flooring, which reduced leg fatigue over long days and offered benefits such as impact noise reduction, high durability and easy cleaning. The simple click-together installation, requiring no adhesives, further underscored the product’s practicality and reusability.

Network coordinator Christina Guth observed enthusiastically broad and positive engagement from diverse sectors including politics, municipal planning, agriculture and landscaping. This sentiment was echoed by Elke Sondermann-Becker of Regupol, who noted that the strong public interest reflected a contemporary demand for sustainable solutions made from recycled materials. The initiative’s message was further amplified through an interactive quiz on the main stage in Hall 27, where attendees could win items like an elegant vase from Conradi+Kaiser or horse figurines, all made from rubber granulate.

During the Green Week Startup Days, Daniel Schockmann from Regupol took to the stage to outline how tyre recycling opens new pathways for a climate-friendly circular economy, highlighting solutions that are both ecologically and economically sound. Meanwhile, a dedicated specialist conference, the PLAYGROUND:TALKS, addressed sustainable urban recreational spaces. Experts including Sabine Rehberg, Dr Georg Maxein and Ralf Hertrampf presented to approximately 150 guests on the critical role of rubber granulate fall protection surfacing.

These elastic, impact-absorbing floors – installable as seamless surfaces or tiles – meet stringent safety standards for indoor and outdoor use, protecting against injuries from falls of up to three metres. They are robust, weather-resistant and slip-resistant while also offering design versatility through various colours and finishes. Beyond enhancing safety and accessibility, such solutions help municipalities and clubs achieve budgetary efficiency and a reduced environmental footprint, proving that innovation in tyre recycling supports both community well-being and circular economy goals.

The Association of Natural Rubber Producing Countries (ANRPC) hosted a significant courtesy visit from Stefano Safi, CEO of the Global Platform for Sustainable Natural Rubber (GPSNR), on 4 February 2026. The meeting, held at the ANRPC Secretariat in Kuala Lumpur, featured substantial discussions with Secretary-General Dr Suttipong Angthong and his team.

Central to the dialogue were the crucial themes of sustainable production and pricing mechanisms, alongside an analysis of recent market impacts on the industry. Both parties affirmed the necessity of collaborative action to address sectoral challenges and committed to a shared path for promoting sustainable growth in the face of evolving market dynamics, ultimately striving towards a more environmentally responsible future for natural rubber.

City of Moreton Bay has been recognised for a groundbreaking road resurfacing programme that sets a new sustainability benchmark for Queensland. In partnership with infrastructure firm Fulton Hogan, the council spearheaded a research and development project to create a durable asphalt solution specifically designed for subtropical climates.

This innovative approach involved trialling a mix incorporating crumb rubber binder with up to 30 percent recycled asphalt pavement. The highly sustainable formula was also produced as a warm mix asphalt, requiring lower production temperatures than conventional methods. Extensive field testing on local roads confirmed the mix's functionality and durability, establishing a viable future-ready surfacing solution for local governments.

The environmental benefits of the 2024/25 programme were substantial. Across 82 streets, the project utilised 7,838 tonnes of recycled asphalt and repurposed the equivalent of 28,748 end-of-life passenger tyres into the road network. This concerted effort resulted in an estimated carbon emission saving exceeding 556,000 kilogrammes.

The Australian Flexible Pavement Association subsequently honoured the project as the Queensland state winner in the ‘Outstanding project less than $10m’ category. This initiative aligns with the City of Moreton Bay’s broader environmental strategy, which includes a target of achieving net zero emissions for council operations by 2039 and reducing the city's overall carbon footprint.

The council views such partnerships as a practical demonstration of its ‘Going Green as We Grow’ commitment, aimed at maintaining materials in circulation to reduce waste. Recognising local roads as one of its largest infrastructure assets, the city continues to actively encourage all resurfacing contractors to pursue innovative and environmentally sustainable solutions. This road programme complements other ongoing green infrastructure projects within the region focused on enhancing safety for both motorists and wildlife.
