Simply put, the roller press is the most energy-efficient grinding machine on the market. Since its commercial introduction into the cement industry by KHD in the 1980s, hundreds of them have been installed in the cement and minerals industries, in both finish and semi-finish applications. And with the lowest specific energy consumption among comparable comminution technologies, including ball and vertical roller mills, it’s not difficult to understand why.
Grind cement raw materials, clinker, and slag, as well as minerals, with a roller press from the technical leader.
The machine frame – open or closed?
We offer both open and closed frame layouts. But what’s the difference? Open frames benefit from quicker erection and easier roller exchange. Rollers are removed sideways, rather than lifted out from above, eliminating the need to dismantle the top frame, bin and feeding equipment. Closed frame, however, offers lower initial machine costs.
Not sure which is going to work best for you? You can rely on our experts to guide you through the decision-making process and ensure your roller-press best meets your requirements.
Wear protection of the roller surface
Wear is a fact of life. But if not properly monitored and controlled, it can end up degrading grinding performance, lowering production rates, and significantly extending maintenance downtime of your machine and production. Deciding the best wear protection for your process is therefore an important task – and one where an expert opinion can help make sure of the best results. Which is where we can help.
Our engineers will take all relevant factors into consideration to suggest the type of wear protection most suited to your application. That might be a welded complete hardfacing (CHF) of the rollers, a cost-competitive option. Or it could be our long-lasting stud lining.
The stud lining comprises extremely wear-resistant tungsten carbide studs that are inserted into the roller surface. The arrangement of the studs on the roller surface is also designed to create an autogenous wear protection layer between the studs, providing an extra level of protection for longest-possible wear life.

You can also check out our roller press maintenance services, including our innovative Roller Press Scanner. This detects potential problems with your roller surfaces early to help planning of your maintenance schedules and reduce downtime.
A unique bearing arrangement
Our unique four-line cylindrical roller bearing arrangement allows a compact machine design, as well as needing only one hydraulic cylinder per side, instead of the two required by roller presses with spherical bearings. And because skewing of the moveable roller is facilitated by a separate rubber thrust bearing and pivoting cylinder, our cylindrical bearings are simpler to seal. This improves the reliability of the lubrication, a key factor in prolonging service life.
Flexible skewing and even load distribution
Skewing of the moveable roller is made possible via a combination of rubber thrust bearing and flat pivoting cylinder. These are mounted between the hydraulic cylinder and the roller bearing housings. The patented rubber thrust bearings also ensure even load distribution across the bearings for longer service life.
A low-energy, reliable, flexible grinding option backed by unparalleled know-how and long years of experience.
Low energy consumption
We said it before. But it’s worth repeating. When compared with other grinding options, such as ball mills and vertical roller mills, the roller press is the most energy-efficient grinding system on the market. Which means lower energy bills for you. So, your production costs will be more competitive and sustainable, both today and into the future.
High availability and reliability
With its unique bearing system, long-life roller surface protection and ease of roller exchange (when opting for the open frame design), our roller presses are designed to provide the highest levels of reliability and availability. They just keep grinding… and grinding… and grinding. And therefore, keep your production flowing, stress-free. Looking for uninterrupted and long uptime? A roller press is the way to go.
Flexible grinding options
Our roller presses are able to grind various feed materials, giving you the option of producing a range of cements at one site. For example, with the appropriate grinding circuit and drive train arrangements, you can switch quickly and easily between clinker and slag grinding.
Going with the experts
As we mentioned in the introduction, we were the first company to install a roller press in the cement industry. And we’ve done so successfully many times since. You might say that makes us the experts – whether it’s for new, greenfield installations or for brownfield upgrades (e.g., adding a roller press to a ball mill circuit to raise production rates and improve energy efficiency). And when you know the experts, why go anywhere else?
