Bearings

The 3x3 mill features greaseless bearings. These are sealed bearings and do not require regular greasing. Tips for longevity of these bearings.

1. A visual inspection to ensure bearings are functioning as they should.
2. Monitor temperature of the bearings during operation. If a bearing is noticed to be overheating or carrying an excessive amount of heat during operation, please contact the RMS Service team.

Chain and Sprockets

The drive system of the 3x3 mill uses a chain and sprocket configuration. This should be a low-wear area; however, if the chain or gear drive system begins to make noise or becomes a concern, a high-quality chain lube can be applied to the chain and sprockets.

Motor Rotation

When looking at the left side of the machine, the motor should be spinning in a counterclockwise manner. This should ensure the rolls are spinning inwards towards each other. See photo below for reference.

Important: Check and clean motors at least monthly to ensure they are free from contaminates. This ensures the motors are able to adequately cool themselves and avoid overheating.

Interlocking

Interlocking the electrical components on a roller grinder is one of the most important steps when installing a machine into a grain handling system. You must interlock the main grinding motors to the downstream take away equipment, an auger or chain disk conveyance system for example, to prevent them from starting if those downstream components are not energized. This is critical to ensure that the roller grinder shuts off if one of the components downstream stops running for any reason. RMS will not be responsible for warranty claims should you fail to interlock your mill with upstream or downstream equipment and failure takes place.

If you’re using the mill as a standalone machine, not tied into a grain handling system, interlocking is not necessary.

MicroMill Installation

Installing a machine on a stand:

The 3x3 mill comes with a mill stand as a standard feature. If the machine is installed on a stand not supplied by RMS, it is critical that this stand is built to handle the overall weight of the machine and product that will be in the machine. As a general rule of thumb, the stand should be built with a 1.5 to 1 safety factor. The estimated weight of a 3x3 mill is 200 pounds.

Bolting machine to the ground:

Concrete anchor bolts must be used when the machine is being installed on concrete. If the machine is being installed on a steel platform, grade 5 bolts or better should be used. Machines should be checked for level, no matter where they are installed, before being secured.

To prevent dust leaks:

If used in conjunction with a grain handling system, any connections to and from the mill should be sealed with silicone calk to keep dust build up as minimal as possible.
