OPERATION
-23-
Mill & Blower Operation
Material enters the cylinder chamber through the mill inlet and
is drawn into the cylinder by a vacuum below the cylinder. The
vacuum below the cylinder is obtained by the physical location of
the blower Inlet below the cylinder.
The 21” cylinder is composed of sixty-six swinging hammers which
are equally divided among three rows around the cylinder. As the
cylinder rotates at the recommended speed of 2700 RPM, the
hammers grind the material and force it through the screen. Once
through the screen, the ground material drops down to the transfer
auger and is conveyed to the mixing tank. Lightweight chaff or
dust is drawn into the blower inlet and forced by the blower up into
the collector where it is refined and separated. Heavy particles
are directed back down into the transfer auger and conveyed to
the mixing tank.
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.
TANK LID
The lid on top of the mixing tank features spring-loaded latches
which enables it to be forced open by overflowing material should
the tank accidentally become filled beyond capacity. The tank lid
will open, allowing the ground feed to spill-out to prevent damage
to the mixing auger and drive components.
IMPORTANT: Stop mixer operation if the tank lid is forced open.
Before restarting to grind or mix, the tank lid must be closed and
latches.
