How to Identify Your Bliss Hammer Mill Model Before You Order Parts
The fastest way to get the wrong part is to guess at the mill it's going into. Before you order hammers, screens or any other replacement component for a Bliss hammer mill, confirm the model and the configuration that's actually in service today.
Here's how to do that, including what to do when the nameplate is missing.
Step 1: Find the Nameplate
Start with the nameplate on the mill housing. Bliss Eliminator designations look like E-4430-TF, E-4436-TF, ED-4440-TF or E-4815. Write down everything on the plate, including any serial number, and take a clear photo of it.
Nameplates on older mills are often painted over, worn, or missing. If you can't read it, don't guess. Move on to steps 2 and 3. Our shutdown inspection checklist covers what to photograph and record the next time the mill is down.
Step 2: Photograph the Mill and the Part
Photos do most of the identification work. Take:
The full mill from at least two sides
The nameplate area, even if it's unreadable
The grinding chamber with the doors open (only after lockout/tagout)
The part you need, on its own and in place
Anything that looks modified or non-standard
Step 3: Measure the Part
Dimensions confirm what photos suggest. For the most common parts, record:
Part | What to measure |
Length, width, thickness, hole diameter and hole spacing | |
Overall dimensions, curvature, perforation size and thickness | |
Rods and pins | Diameter and length |
Spacers | Inside diameter, outside diameter and width |
Wear liners | Overall dimensions, thickness and mounting hole locations |
Measure a worn part where it's least worn, and note that it's worn so we can account for it.
Step 4: Check for Changes Since Installation
A mill that's been running for twenty or thirty years has often been rebuilt, re-rotored or modified. The original parts list tells you what the mill shipped with. It doesn't tell you what's in it now. Note any past rebuilds, replacement parts from other suppliers, or changes to the rotor, screens or feed.
Step 5: Record It for Next Time
Once the model and part are confirmed, save the information where the next person can find it: model, serial number, photos, dimensions, supplier and part number. The second order should be easier than the first.
What Comes Next
With the model and part identified, compare replacement options on fit, material, balance, lead time and support. Our guide to Bliss hammer mill parts explains what to look for, and Bliss Eliminator hammer mill parts lists what we make for each Eliminator model.
Frequently Asked Questions
Where is the model number on a Bliss hammer mill?
On the nameplate on the mill housing. Eliminator designations look like E-4430-TF, E-4436-TF, ED-4440-TF or E-4815.
What if the nameplate is missing or unreadable?
Send photos of the mill and the part, plus key dimensions. In most cases that's enough to identify the model and the part you need.
Why isn't the model number enough on its own?
Older mills have often been rebuilt or modified, so the parts in service may not match the original specification. Dimensions and photos of the actual part confirm the fit.
Can you work from the old part?
Yes. If you can ship us the existing worn part, we can work directly from it.
