We urge you to read the publication carefully and refer to it extensively for correct operating procedure. The Renn Auxiliary Mill is designed to give the operator a maximum capacity and working surface through the use of a large diameter roll. Added to this is a conven- ient method of roll removal and a new process of roll adjustment, giving the opera- tor infinite control of feed quality.

3 DECAL LOCATIONS 3.1 Safety Decal Locations The types of safety decals and locations on the equipment are shown in the following illustra- tions. Good safety requires that you familiarize yourself with the various safety decals, the type of warning and the area, or particular function related to that area, that requires your SAFETY AWARENESS.

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-...
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 knob (Figure 4.5) 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 3/4” Flat Washers Compression Spring 3/4” NC Hex Nut 3/4” NC Jam Nut For correct belt tension, adjust compression spring (Dim ‘A’) to: 8 Belt systems: 4 Belt Systems: 2-7/8” - 3” long 3”...
4 OPERATION 4.4.8 Grate Magnet The grate magnet has slits on the edges (Figure 4.10). These can be removed with pliers to ex- pand the top opening. This modification may aid in improving material flow when milling wet grain. Figure 4.10 4.4.9 Auger Set Up 1.
4 OPERATION 4.4.9 Auger Set Up (Cont’d) Once opened, you can use the hydraulics to lift the auger up until it is cleared to swing into position. The in feed auger can now be lowered into the needed position (Figure 4.13). The in feed auger is equipped with a free swing mechanism (Figure 4.114).

4 OPERATION Figure 4.15 Dim A Figure 4.16 For correct belt tension, adjust compression spring (Dim ‘A’) to: 8 Belt systems: 4 Belt Systems: 2-7/8” - 3” long 3” - 3 1/8” long NOTE: Whenever possible it is always best to minimize belt tension.
4 OPERATION 4.6 Roller Mill Break-in It is recommended that the mill be run at moderate to full operational speed and at 1/2 to 2/3 capacity during the first hour of operation. This allows the frictional forces to diminish signifi- cantly within the auger tube, and allows the free flow of grain to approach acceptable levels in the system.
4 OPERATION 4.7 Reduction Gearbox The reduction drive option included with this mill enhances the variety of applications beyond those of the standard mill to include bagging, blowing, and any other secondary application requiring the same or a reduced input power. The reduction box can be used to run the secondary machine at speeds of 540 or 1000 RPM.

5 SERVICE AND MAINTENANCE 5.2 Servicing Intervals (Cont’d) Transfer auger bearing: grease zerk (every 10 hours) For discharge gearbox oil level check - 1. Take out the gearbox. 2. The oil plug is located on the side of the gearbox. 3.
5 SERVICE AND MAINTENANCE 5.3 Removal Of Rolls For Servicing 1. With the power disconnected, loosen the jam nuts on each of the spring push bolts and re- lieve all pressure from the spring (see section 4.4.6). 2. Relieve the tension on the roll drive belts and remove. 3.
6 PDI SETUP Your Renn Mill may come with some parts pre-assembled. Note: • Practice proper safety procedures when lifting heavy objects. • Parts illustrated on these pages are to demonstrate what parts may need to be assembled. • All hoses should be on the hose hanger when not in use.
Page 34
6 PDI SETUP 1. Remove existing washers/nylock nuts on the top of the discharge auger and use it to fasten the discharge chute and spout cap together to the auger. 2. Remove the clamp band from the top of the gearbox. 3.
Page 35
6 PDI SETUP 5. To secure the discharge auger in place, attach the support arms on both sides, using the existing hardware. How to use the hose hanger: A) Open the quick pin that is holding the lock plate and the front panel of the hose hanger.
7 TRANSPORTATION 1. Check with local authorities regarding mill transportation on public roads. Obey all appli- cable laws and regulations. 2. Always travel at a safe speed. Use caution when going around corners or meeting traffic. 3. Make sure an SMV (Slow Moving Vehicle) emblem and all the lights and reflectors that are required by local highway and transportation authorities are in place, are clean and can be seen clearly by all overtaking and oncoming traffic.
8 STORAGE 8.1 Placing in Storage At the end of the operating season, the machine should be thoroughly inspected and prepared for storage. Repair or replace any worn or damaged components to prevent any unnecessary down time at the beginning of the next season. Follow this procedure: 1.
