 | Keep foreign material (nuts, bolts, rocks, etc.) out of your product |
| Have the proper number of hammers in your mill - too many hammers or not
enough hammers cause some of the problems. |
| Maintain the proper hammer to screen clearance for your particular
product. |
| Use screens with the holes staggered in the grinding direction. |
| Use an air assisted system on your mill. |
| Install magnets to remove metal. |
| To learn more about hammermill maintenance, request your free copy of

| Several things can cause a hammermill to vibrate, some of these are:
 | Hammers not balanced properly |
| Hammer rod grooving |
| Hammer hole elongation |
| Uneven wear on the hammers |
| Hammer pattern improperly installed |
| Hole elongation in rotor hammer rod holes |
| Wear on the rotor plates or shaft (especially rotor end plates) |
| Motor coupling not properly aligned |
| Improperly feeding the hammermill and causing surging |
|
| Call us at 1-800-899-4072. We will be glad to help

| Loss of capacity |
| Increased energy consumption - watch the % loaded meter or the ampere
meter very closely |
| A change in your ground product |
| Maintenance records indicating past changes in tons, hours, days, weeks,
or months |
| Dull screens and worn out hammers are very inefficient and are detrimental to both your
capacity and quality |
| No, hammermills vary greatly. No one hammermill is designed to do
all types of grinding. Some factors to consider when choosing a
hammermill are: product, fineness, particle
size distribution, air relief systems, service from the OEM, experience
of the OEM with your product, available space and budget. |
| Try to talk with other people in the industry who have experience grinding
your product and find out what has worked or not worked for them. |
