Hammers, Hubs & Screens
Top quality replacement parts for hammermills and grinders are a part of EAI's full line of feed processing systems.
We provide all the necessary parts to keep your grinding equipment operating at maximum efficiency.
Hub and Hammer Accessories
Hammermills and grinders operate at top speeds of 3500 rpm.
This constant repetition can cause damage to the hub assembly.
The holes in the rings become elongated and the bolts grooved from excessive wear.
Hammers should be replaced to maintain balance in the sequence of the rotation of the hammers.
Complete assemblies include:
  • hammers (set of 15)
  • swing pins (set of 3)
  • spacer sets (required due to the thickness of EAI hammers)
Hammers are reversible items. Hammers can be reversed for longer life.
They are movable in groups of three to maintain sequencing and balance of hammers.
