Please take a few minutes to read the instructions to help eliminate many of the problems frequently encoun- tered. Keep in mind at all times that the stoner is not a "cure all" for the processor's problems. The stoner is a spe- cialized piece of machinery designed to do one job very well. THE STONER SEPARATES PARTICLES OF A SlMlLAR SIZE THAT DlFFER IN WEIGHT, ELlMlNATlNG HEAVY TRASH AND STONES. -

After your stoner is mounted on a secure foundation, you are ready to install the motor and make the connec- tions. If you ordered your stoner with a motor, it will be installed at the factory; and you will only be required to make the necessary electrical connections. -

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. -
Page 7: Iii. How Does A Stoner Work
Figure 1 below represents a cross section of the stoner directly over a fan. A particle mixture has been introduced on top of the screen deck with the fans off. -
Page 8: The Theory In Practice
THE THEORY IN PRACTICE Figure 4 represents a top view of the ideal situation in the operation of a stoner 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. In this area, the vibration of the deck and the lifting action of the air combine to stratify the material into layers with heavier layers on the bottom and lighter layers on the top as shown by Figure 2. - Page 9 FORWARD BACKWARD This sketch is a sectional diagram of what occurs on a stoner deck. Compressed air forced through the mesh of the deck cover lifts the lighter particles upward, while heavier particles sink against the air currents and come to rest on the deck surface, providing the air is properly adjusted. The heavier particles are forced to travel uphill by mechanical action, while the lighter particies float downhill on a film of air.

An example of this would be the separation of adobe from pinto beans where the particles are nearly the same size and the weight as well. In cases such as this, the stoner must be operated at a lower capacity; and one should expect a lower quality separation. -

THE DECK The most important part of the stoner is the deck, because it is the main separating surface. It consists of a carefully constructed wooden frame to counteract false vibrations with a screen or cloth overcover that is the surface on which the separation takes place. -
Page 12: The Four Basic Adjustments
Oliver Stoners have one, two or three stone discharge traps depending on the model. The Oliver Model 2448 Stoner has one stone trap. The Model 3648 Stoner has two stone traps, and the Model 4848 Stoner and the Model 6048 each have three stone traps. -
Page 13: Air Adjustment
AIR ADJUSTMENT Air regulation is one of the most important adjustments to be made on a stoner. The most common mistake in air regulation is the use of too much air. Separation is not made by "blowing" the light material from the heavy but by using a controlled air flow to create the stratified layers, which are then separated by the vibrating action of the deck. -
Page 14: Start Up And Operatlon
V. START UP AND OPERATION 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. - Page 15 3. On many products a zone of light material will form at the lower edge of the bed as the deck fills. This is normal and indicates that sufficient air is present. If the percentage of heavy material is high, you may note the beginnings of a heavy separation in the heavy discharge area.

Page 16: Lncreasing Capacity
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. -

Do not attempt to operate the machine without an understanding of why it works. The more one understands any situation, the better he is able to cope with it. Your stoner makes a separation based on a particle's weight and its resistance to air flow. Proper adjustment of all the controls is necessary to obtain the best sep- aration. - Page 18 9. Attempting to separate commodities unsuitable for separation. This is a very rare problem, as normally a stoner will make some improvement in any seed lot. However, a stoner is a specialized machine designed to separate particles of varying density and similar sizes. If material does not fall into that classification, then it probably cannot be separated on a stoner.
- Page 19 From this point you can make the necessary adjustments to obtain an optimum separa- tion. 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 Figures 12-13-14.)

DRIVES There are three sets of belts and sheaves in your Oliver Stoner. These are the main drive belts or fanbelts; the idler belt from the fanshaft to the vari-speed unit, and the eccentric belt from the vari-speed to the eccen- tric shaft. -
Page 21: Vari-Speed Assembly
Install the eccentric belt. Turn the machine on and set to the required speed. BEARINGS Your Oliver has several bearings to support the shafts. These bearings are all standard sizes and can be pur- chased at any bearing supply house, or we can supply new bearings. Normally, a bad bearing will first be detected by hearing an unusual rumbling noise in the machine. -

5. Tighten the jam nuts. 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 insure that you receive the correct parts, we must have the serial number of your machine. -

Remember, the stoner is not intended to be a cleaning machine. With some commodities, dust is still present on the particles when they are introduced onto the stoner. 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. - Page 24 return to index...
