ADJUSTMENT OF THE ABRASIVE
SEPARATOR
To function properly, the abrasive
separator must have an adequate air flow. The
double lip separator on this unit will require a
minimum air flow of 400 CFM in order to
function efficiently. With the correct air flow,
the abrasive separator can be adjusted as
follows.
Abrasive enters the separator through
the rotary scalping screen. (Item A) The
screen permits the abrasive to fall through, but
carries trash and tramp metal out of the
separator. Abrasive falls down in the upper
portion of the separator against an adjustable
spreader gate. (Item B) This gate should be
adjusted up or down to cause the abrasive to
spread out the entire 20" width of the
separator. This adjustment should be made
with the swinging gate removed. (Item C) If
the area around the rotary screen should fill
with abrasive, the spreader gate should be
raised slightly to permit free abrasive flow.
With the swinging gate in place (Item C) the
abrasive should form an even curtain across
the entire width of the separator. Fill the
cups, located on the swinging gate, with
abrasive to control the curtain. The abrasive
should form a constant and even curtain.
