Pellet Mill Roller Shells

Importance of Rolls in Pellet Milling

The pellet mill roller shell assemblies are a critical component of the pellet mill. The roller shells play a key role in determining the quality and consistency of your pellets. We recommend you replace your roller assemblies with each die change. A worn or damaged roller shell being used beyond its service life can cause the mill to consume more energy and reduce throughput.

Quality Construction

Elevate your pellet production with our top-quality roller shells. Our roller shells are designed to withstand the high pressures and abrasive forces of the pelletizing process, ensuring a consistent and efficient outcome every time.

Roller Shell Material

Our roller shells are made from high quality materials that are proven to withstand high temperatures and pressure without degrading or warping.

Choosing the right Roller

Customizable options and smooth surfaces allow for optimized performance and reduced friction, while easy maintenance helps reduce downtime.

Corrugated Open End (HT)

Our corrugated open end shells work best with high-fibrous products such as wood. One benefit is the relief of pressure on the face of the die.

Corrugated Closed End (HTW)

Designed for more lightweight products, our closed end corrugated shells hold the product you are pelleting to the die pad and can improve throughput.

Tungsten (TRC)

Our Tungsten coated shell is best used in high-mineral applications such as corn gluten. Take care not to over-tighten your shells as it could be detrimental to the die.

Dimple (HTD)

Jacobs Dimple shells are less aggressive and most successfully used in wood applications.

Corrugated Helical (HTWH)

Jacobs Helical shells were designed with corn-based animal feed in mind. They work well in a three-roll set up and tend to do a better job cleaning off the die pad.

Pinnacle

Pinnacle shells do an exceptional job in applications producing poultry feed. They are aggressive, holds the feed to the pad, and in most cases improves throughput.

Dominator Shell

Jacobs Dominator™ Shell is a harder shell that typically lasts the life of the die. We have availability in all styles for most makes and models of pellet mills.

Assembly Parts

Jacobs carries internal components to aid in your roller assembly rebuilds. Please reach out to your representative for availability and a quote.

"The Lightning resulted in 48% decrease in energy with 19% increase in throughput. Savings $32K!"

Ron, Mill Manager

"The Pentagon Hammer Set we have in our Roskamp meal grinder is working very well. I'll be buying at least two more Sets of these hammers for our other machines."

Maintenance & Reliability Leader

"Feed flow did increase, we were able to turn them up and get more AMPS on our ground grain elevator. Very satisfied with the Pentagon Hammers. Showed them to sister plant and he is interested in getting a set. I told him I was sold on them."

Plant Manager

"Very pleased with Bad Ax Hammers. Mill has less vibration, first corner 250 to 260 hours, 2nd corner at 180-190 and still going"

Plant Owner

"Our pelleting process had some inefficiencies, we were seeing rather poor performance from our process and short lifespans from our dies and rolls. . With Jacobs we built a new protocol for our process, from our feed temps, all the way through roll setups. We have been running for several months now and our pelleting production numbers are fantastic, some of our products we increased our performance by over 50%, that translates to multiple tons per week in increased efficiency. We did see an increase in all of our TPH across the board. "
