Hammer Mill Replacement Hammers

Custom Hammers to Fit Your Specific Grinding Needs

Jacobs cutting-edge technology allows us to create custom hammers to fit your specific grinding needs. Our professional sales team is extremely knowledgeable in helping you determine factors, such as what hardness of hammer you should be using, what size of tungsten, which style of hard-facing, and if it makes sense to have a 1- or 2-hole hammer in your hammer mill. Jacobs hammers now all feature our TruBore™ holes, which provide true hammer-to-rod contact, mitigating hole elongation and rod grooving.

Dagger ™

Made for minimum wear and maximum destruction! Our Dagger hammers are powered by Holeformance™ - a Jacobs proprietary technology that eliminated rod wear with 100% rod contact, two times faster installation, eases removal, and helps mitigate hammers sticking.

Ask about our clusters for even faster installation, additional reduction in hole elongation and rod grooving. Dagger clusters also result in a better grind profile and reduce hard-face undercut wear.

One part number, one kit.

Pentagon ™

Designed with the Ethanol Industry in mind, Jacobs Pentagon hammers are built for harsh environments. The durability and ease of install are just a few of the reasons these hammers are leading the industry. Pentagon hammers are powered by HoleFormance™-mitigating hole elongation and rod grooving while greater clean-out reduces hammer sticking.

The notched end provides a secondary grind point resulting in increased throughput and a better grind profile. Pentagons typically run at less amps allowing you to dial up the feed rate to produce more tons for the same energy costs of competitors hammers. Typical install and removal time is half that of the competitors’ hammer set up.

Our engineering team is standing by to help develop the best set up for your mill. This process begins with a questionnaire to help establish your production goals as well as to address any issues such as locational wear, micron size, longevity, and performance. Once developed your set up will come complete with a pattern and will utilize one part number for hammers, rods, spacers and lock collars for ease of ordering.

Max™ Hammer

Jacobs Max hammers are designed with a serpentine bushing that mitigates rod wear, drastically decreasing installation and extraction time. Max hammers come dynamically balanced in clusters ready to set in place and stay in place. Other benefits include but are not limited to a reduction in amps and less drag in the mill.

Max hammers provide the best rod grooving and hole elongation protection of any hammer in the industry. Get more revenue-generating operating time out of your mill. Give us a call to discuss compatibility with your operation.
