Put our die expertise to work
Whether you need a new die, want to build your stock, or need expert advice, our specialists are here to help.
Roller shells for pellet mills
Build consistent output from the first rotation.
A roller shell does more than create traction. Its profile and material influence how evenly raw materials are fed, distributed, and compressed. ANDRITZ experts help you select the right specification for stable pelleting, consistent throughput, and balanced wear.
Multi-brand expertise
We offer roller shells compatible with a wide range of pellet mill manufacturers, so you can simplify sourcing while maintaining reliable performance.
Built to your specifications
Choose from multiple materials, hardness levels, corrugation and dimple profiles, dimensions, and bore designs to match your process.
Suitable for every application
Designed for animal feed, pet food, aqua feed, biomass, waste recycling, and other pelleting applications with profiles optimized for different raw materials.
Roll repair services
Worn shells can be replaced while the original bearings are retained and reused, reducing waste and avoiding the need for a completely new roller shell.
New: Tungsten carbide roller shells
Last up to 6x longer and reaches up to HRC 70–75, approaching diamond-level hardness. This exceptional surface hardness helps withstand constant abrasion and significantly reduces wear in demanding, high throughput applications.
Material strength matched to your process
From case-hardened shells for standard applications to through-hardened shells for demanding conditions, ANDRITZ helps you choose the right material and hardness for reliable traction, controlled wear, and longer service life.
Corrugated and dimple roller shells designs
Different roller shell profiles are designed for different materials, recipes, and production goals. From high-fiber feed and biomass to high-fat formulations, the right profile improves grip, reduces slippage, manages wear, and supports stable pelleting performance.
Plan your roller shell needs with confidence
Whether you need new roller shells, repair support, or advice on future stock, our specialists are ready to help.

Frequently asked questions
Can't find the answer here? Our support team is happy to help.
In most cases, yes. We supply dies and roller shells for ANDRITZ pellet mills and for many models from other manufacturers, so you can bring more of your parts sourcing under one roof. Every mill is a little different, so tell us what you're running, and we'll confirm what we can offer.
The mill model is only the beginning. Your raw materials, pellet size, compression, hole pattern, and production goals all shape the die you need. It's a lot to weigh up, which is exactly where we can help. Share what you produce, and we'll help you find the right die.
Quite a range. We offer dies in various chrome steel alloys, hole patterns, compression ratios, and specifications tailored to your raw materials and operating conditions. The right combination depends on how you produce, not just what you produce. Tell us about your application, and we'll help you match the material and specifications to the job.
It comes down to how your material behaves inside the mill. The surface profile and material influence how evenly the product is fed and pressed against the die, and the right choice makes all the difference. Tell us about your application, and we'll guide you to the right roller shell.
Very often, yes. Depending on the part, we can adapt materials, dimensions, designs, and surface profiles so they suit your mill and your recipe, rather than a generic standard. Tell us what you need, and we'll explore what's possible for you.
More than most parts on the line. Together, they shape how your material is compressed and formed, which influences pellet hardness, consistency, and throughput. When both are well matched to your process, quality gets easier to hold. Want to get more from your pellets? Let's look at your setup together.
Several things play a role, including abrasive raw materials, moisture, operating conditions, alignment, and how the parts are matched to your process. Understanding what's driving the wear is the first step to slowing it down. Seeing faster wear than you'd expect? Get in touch, and we'll help you get to the bottom of it.
