FAQ's

Frequently Asked Questions

When is it time to have my rolls exchanged or sharpened? Here are things to look for:

1. Low motor amps and reduced capacity. Instead of it taking six hours to process it may take eight hours.

2. Poor feed quality. The rolls will be doing more crushing than grinding, resulting in excessive powdering.

How long can I expect my rolls to go in between changes? 

Factors to consider:

1. Do you have the proper protection, such as a magnet or scalper system?

2. Is the machine you are using the correct size for your application? Typically, Roll life is primarily dependent on bushels ran compared to the size of the machine. Rolls should last at least two years between sharpening. Less than that and you are paying too much for service calls, bearing replacement, downtime and possible overtime. You WILL save money, by trading up for a larger Mill!

How long between requesting a Roll Change from RMS will I have to wait for RMS to come to my facility? 

Depends on:

 1. If it is an emergency, we can be there immediately.

2. If it is not an emergency, we try to group you in with a trip with other customers in the same area. This will save you money, as you will be splitting the cost of travel expenses. We recommend calling in at least one month ahead of time to get a "grouped in" rate.

3. If  you have a specific date in mind and you do not want to wait for group pricing, let us know. We  work around your schedule!
