4 OPERATION 4.1 To the New Operator or Owner The Renn Mill is designed to receive dry grain from an auger, process it, and deposit it via the discharge auger. Be familiar with the machine before starting. In addition to the design and configuration of equipment, hazard control and accident preven- tion are dependent upon the awareness, concern, and prudence of personnel involved in the op- eration, transportation, maintenance and storage of equipment or in the use and maintenance of facilities.
4 OPERATION Setting up the Roller Mill 4.4.1 Roll Setting Figure 4.1 Figure 4.2 Loosen the wing nuts holding down the top hopper (Figure 4.2) and tip it over center, rotating on the hinge pin until it hits the stoppers. If using flat rolls to roll dry grain, set the rolls a very small distance apart.
4 OPERATION 4.4.2 Roll Gap Adjustment The cam control ( Figure 4.4) serves as a mechanism to make roll gap adjustments accurately and quickly using a 3/4” wrench or socket. The cam positional indicator is set at the factory to the “1”...
4 OPERATION 4.4.3 Feed Gate Control Set the friction nut/washer (Figure 4.6) so that it supports the weight of the feed gate and yet allows the gate to be opened and closed by hand. Note that the setting of the feed gate helps to spread the feeding of grain evenly across the face of the roll.
4 OPERATION 4.4.6 Roll Drive Belt Tension To increase belt tension, loosen the jam nut and turn the tensioning bolt until approximately 15lbs of force at the center of the longest belt span causes a 3/8” deflection. Reset the jam nut to lock the adjustment bolt in place.
4 OPERATION Leaf Spring Pressure (24” Roller Mill) Deflection (in) lbs/in 0.625 Factory Setting 0.750 Max for bearings 4.4.9 Auger Set Up Setting Up The Discharge Auger: The discharge auger is equipped with a central hinged folding section, allowing the auger to be folded up, thus reducing height for storage.
4 OPERATION 4.5 Operating the Roller Mill 1. Make sure to read and understand all of the safety items in Section 2. 2. Ensure that the feed gate is closed (Figure 4.6) before starting the mill. Even a few grains will keep the rolls from turning.
