HYDRAULIC OPERATED ATTACHMENTS
Swinging Intake Auger (SIA)
An optional hydraulic drive Swinging Intake Auger (SIA)
attachment conveys material into the mill. The intake
auger can be swung in and locked against the mixer tank
support brace for transporting, or swung out and locked
at any point. Operating height of the infeed hopper can
be raised or lowered and held in position using the rope
mechanism. The attachment is spring counterbalanced
to help with lifting. The right portion of the infeed hopper
folds in to reduce overall width for transporting.
SIA Variable Speed Control Valve
Speed control handles are provided for regulation of the speed of
conveyor auger rotation. Movement of any one of the three
mechanically interconnected handles enables stopping and starting
auger rotation as well as regulating the feeding rate of material being
fed into the mill hopper. Two other convenience features on the SIA
are an enclosed wind and grain shield, which is located over the
discharge end of the SIA trough, and a water drain plug which is located
in the bottom of the trough infeed hopper.
GRAVITY FEEDER
The standard equipment gravity feeder is a stationary hopper with
no moving or running parts. Material to be ground is dumped into
the hopper and slides directly into the mill inlet. A combination
steel/rubber splash plate prevents the material which is being fed
from being kicked out by the mill cylinder.
MAGNETS
Two heavy-duty 4" x 18" magnets located in the gravity feed hopper
remove any metal that may accidentally mix with the material
entering the mill.
