flow. 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. The maximum rate is the highest rate at which you still obtain an
acceptable separation. Between these limits the quality of the separation
generally goes down as the capacity is increased and up as the capacity is
decreased.
TILT
is the difference between the high and low ends of the deck. Normally, tilt
should be set at the maxi- mum where you can still maintain an acceptable pattern
across the deck. Too much tilt is present when material cannot be made to climb to
the high end of the deck. Too little tilt is present when you cannot float material to the
low end of the deck.
ECCENTRIC SPEED is
the rate of oscillation of the table. Eccentric action
provides the agitation so that the material can be stratified, and the reciprocating
motion separates the heavier lower layers from the lighter upper layers of
material. Eccentric motion and tilt must be balanced to get the best separating
action. Too much eccentric speed will cause material to flow to the high side of the
deck. Insufficient eccentric speed will not agitate the material enough for proper
stratification. Usually, with too little eccentric speed, material will lay on the table
without moving and the table will quickly become over loaded.
AIR
is used as the stratifying agent. Unless material is properly stratified initially,
a good separation cannot be obtained. Too much air will cause a bubbling, boiling
action that remixes the material as fast as it is stratified. Too little air will not
stratify the material properly.
