Page 7: Introduction
CONGRATULATIONS! You have just purchased a well-built machine that can earn substantial profits for you, if you take time right now to understand the Oliver Stoner N and how it works. Please take a few minutes to read the following document. -
Page 8: Installation
2.1 De-Skidding and Uncrating Although Oliver is built to give years of service, it can be damaged while uncrating. First the top of the crate should be carefully removed. Then take off the sides. After the top and sides are withdrawn, the Oliver Stoner can be disengaged from the bottom of the crate by removing the four 3/8"... - Page 9 Location. The selected location for the installation must also have sufficient space around the equipment for proper ventilation. Do not block the equipment airflow filters. The selected location must have sufficient space around the Electrical cabinet (if equipped) for working clearance as prescribed by the National Electric Code Selection 110-26 or local Authority Having Jurisdiction.

Page 10: Electrical Requirements And Precautions
2.3 Electrical Requirement: After your stoner is mounted on a secure foundation, you are ready to make electrical connections. The Stoner comes with a complete electrical cabinet that is wired to all the electrical components, such as the motors, reference keypads and dust hood light. Typical voltages would be 230V and 460V, three-phase, at 60 Hz, however other voltages can be accommodated. -
Page 11: Clean Air Source/Exhaust
After the stoner is installed and the motor wired so the fans rotate in the proper direction, familiarize yourself with the theory behind stoner operation and the proper usage of the controls before attempting to make a separation. Oliver advice to the customer is to follow local code and regulation for exhaust system. -
Page 12: Functional Operation Of The Stoner
1 will float and particles with a specific gravity greater than 1 will sink. Oliver stoners use air as a standard rather than water. Since air is lighter than water, the relative difference between particles of differing weights is widened. For this reason, the stoner is a very, sensitive machine and, when operated correctly, can produce a very precise separation. -
Page 13: The Theory In Practice
Figure 2: Stratification process 3.2 Theory in Practice. Figure 3 represents a top view of the ideal situation in the operation of the seed mixture, similar to Figure 1, falls from the feeder onto the deck. The area immediately under the feeder is called the stratification zone. - Page 14 However, the stratification area is small when removing rocks or stones from beans, because there is a large difference in weight. Higher capacities likewise require greater areas for stratification. Once the material is stratified, the vibrating deck begins pushing the heavier layers in contact with the deck uphill toward the stone discharge.
-
Page 15: Figure 4: Sectional View Of Stoner Deck Operation
(See p. 1.). This pre-sorting enables separations that are otherwise impossible. There are three guide- lines developed by the late Oliver W. Steele that state what can be separated and what cannot be separated on a gravity separator or stoner. -
Page 16: Guidelines For Use Of Stoner
3.3 Oliver’s Guidelines for Use of Stoner Rule 1. PARTICLES OF THE SAME SIZE BUT DIFFERING SLIGHTLY IN SPECIFIC GRAVITIES CAN BE SEPARATED. A common example of this would be the separation of similar size stones from seed where the stones are heavier than the seed. -
Page 17: Control Components Of The Stoner
Oliver Stoners have one, FIGURE 5 two or three stone discharge traps depending on the model. The Oliver Model 2448 N Stoner has one stone trap. The Model 3648 N Stoner has two stone traps, and the Model 4848 and 6048 N Stoner each have three stone traps. -
Page 18: Figure 6: Stoner Controls
4.2 STONER ADJUSTMENTS All Stoners have four variable adjustments that must be properly adjusted and balanced to obtain optimum separations. These are Feed Rate, Tilt, Eccentric Speed and Air Control. We will discuss the controls for each of these variables in turn. -
Page 19: Feed Rate
START/STOP BUTTON: The START/STOP button controls the machine start and stop of this Nautilus stoner. When start button is pressed, it will start air, eccentric motion, timer for the high-end gate and activate the dust hood light. When stop button is pressed it will stop the operation of the stoner completely. -
Page 20: Tilt
which the deck can be fed and still obtain the necessary separation. When starting your stoner, always start at the minimum feed rate; obtain your required separation, then increase the feed rate to the desired capacity. TILT: Tilt is the difference in the elevation between the high end of the deck and the low end of the deck. -
Page 21: Eccentric Speed
VFD ECCENTRIC SPEED: Eccentric speed and tilt are closely related. Increasing eccentric speed will cause material to be shifted towards the high side of the deck. Decreasing eccentric speed will cause material to be shifted toward the low side of the deck. Generally, by increasing eccentric speed (which shifts material toward the high side) and increasing tilt (which shifts light material back toward the low side) a more precise separation can be obtained. -
Page 22: High End Pnemuatic Gate Control
Too much air will cause a boiling or bubbling action lifting the light and heavier particles from the deck and exhaust most of the material to dust collection system. Too little air will cause the dust escape to the light end of the stoner and containment the light fraction material. -
Page 23: Figure 10: Gate 3-Way Swtich On The Console
On the console, we also have High end gate override switch which can be operated independent of the timer. This is three-way switch, which operates the gate close/open and auto. Close/Open will independently open or close the high gate and Auto will automatically open or close the gate with the timer settings. FIGURE 10: GATE 3-WAY SWTICH ON THE CONSOLE Page | 23... -
Page 24: Start Up And Operation
V. START UP AND OPERATION OF STONER 5.1 INITIAL STARTING PROCEDURES An experienced Oliver operator should have little trouble starting the stoner and obtaining good results. However, for many of us, the confusion that results when the machine is initially turned on defies description. Many of the initial adjustments must be made soon after material is fed onto the deck. - Page 25 5.2 HI-CAP N STONER OPREATION PROCEDURE 1. Set the eccentric speed and tilt to approximately their maximum setting. Set VFD air sped to 15% for small material and about 30% for material larger than 1/8". Open the feed gate slightly and adjust the eccentric speed so that the material spreads uphill slightly faster than downhill.
-
Page 26: Increasing Capacity
5.3 INCREASING CAPACITY The above discussion gives the general procedure for starting and operating an Oliver Stoner. After obtaining satisfactory results at low capacity, increasing capacity is a relatively simple operation. Only after satisfactory results are achieved should this be tried. - Page 27 Increasing the feed rate. Next open the feed gate slightly. This increases the feed rate and the bed depth will increase. Wait a couple of minutes to observe the change in the material on deck. As the bed depth increases over the deck, it may be necessary to increase the air setting slightly to compensate for the thicker bed.
- Page 28 Proper adjustment of all the controls is necessary to obtain the best separation. As we have mentioned, your Oliver Stoner has four adjustments - Feed Rate, Tilt, Eccentric Speed and Air Control. FEED RATE determines the capacity of the machine. The minimum feed rate is the lowest rate of feed at which you can maintain an adequate cover over the entire deck.
- Page 29 A six-inch concrete slab is best but is not essential. Many processors run Oliver Stoners on wooden floors with no problems. If you can feel any vibration in the floor while the machine is running, you probably have too weak a foundation.
- Page 30 standards to be met and the quality of the material being fed onto the stoner. Quality and capacity are inversely related, that is, increasing capacity usually lowers quality and decreasing capacity usually improves quality. Loose clamps. Loose clamps are not a common problem, but they occur more often than people realize.
- Page 31 Wrong adjustment. This is most commonly a problem with new, inexperienced operators. The solution to this problem is usually more experience. Do not be afraid to make adjustments on the machine. Make an adjustment. Wait a couple of minutes to determine the effect. Then decide if it is good or bad. If the effect is good, then try something else for further improvement.
- Page 32 As an additional aid in setting your stoner, we have provided some examples of situations that can occur and have listed adjustments which help correct the pattern. (See Figure 14.) FIGURE 14A FIGURE 14B FIGURE 14C Correct Adjustment 1. Insufficient Tilt. 1.
- Page 33 This can be both annoying and illegal. Oliver has two systems to combat dust and get it away from the machine. These are described in the enclosed brochure on our dust control methods. Please take time to read this, if excessive dust is a problem in your processing.

A.1 – Recommended Maintenance items Hi-cap “N” stoner are designed to give years of trouble-free service. However, as with all machinery, periodic maintenance is required to keep it in top condition. The following is a list of some areas that can be problems, if not periodically checked. A.1.1 –... -
Page 37: Belts And Sheave
A.1.2 BELTS AND SHAEAVE: There are two sets of belts and sheaves in your Oliver Stoner. These are the main drive belts or fan belts; and the eccentric belt from the motor to the eccentric shaft. -
Page 38: Air Filters(Non-Heat)
A.1.4 – Air Filters The Hi-cap “N” stoner come equipped with air filters on the side of the blower frames, they are designed to screen dirt out of the air before it enters the machine. If they become plugged, the fans cannot pull enough air through them to provide proper stratification. -
Page 39: Inadequate Foundation
A.2.3 – Inadequate Foundation Although the Hi-cap “N” stoner is counterbalanced, it must be attached to a secure foundation. If any vibration can be felt in the floor while the machine is running, the foundation is probably too weak. Weak foundations can lessen the ability of the eccentric motion because the foundation absorbs some of the eccentric motion. - Page 40 ORDERING REPAIR PARTS We maintain a complete card file on all machines that have been built by Oliver Manufacturing Company. All machines are serial numbered. To ensure that you receive the correct parts, we must have the serial number of your machine. The serial number is located on a plate on the side of the air chest.
