2.
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. Continue increasing the
feed rate until you reach the maximum feed rate where you still obtain the desired
separation.

High end Gate operation.
Heavy discharge should adjust by high gate control timers to maintain 8 to
12 inches heavy fraction build up on the deck outlet. Typically, open timer is
set to be in seconds and close timer is set in minutes. Depending percentage
of heavy fraction, both this timer can be adjusted to seconds, minutes or
hours. Refer the appendix D for the timer dip switch settings.
5.4 IN CASE OF DIFFICULTY - TROUBLE-SHOOTING
Most stoner operators can get acceptable separations after working with
the machine for a few minutes. However, in some cases, even experienced
operators run into problems that they cannot solve. If your stoner is not giving
satisfactory results, or even if it is, but you would like to see better results, we
suggest you read the following paragraphs.
Many operators expect results too soon on their stoner. When an adjustment is
made, you should wait at least two minutes before deciding whether the
adjustment has made any improvement. The reason for this is that, because of the
volume of material on the deck, a certain amount of time is required for the deck
surface to adjust to the new conditions.
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 resis tance to air
