OPERATION (cont.)
SCREENS
Uniformity of grinding is a factor of mill speed, condition of the hammers,
and sharpness of the screen. The efficiency of the mill will also decrease
if the holes of the screen are badly worn. If grinding fineness is deteriorating,
the screen should be rotated to place the sharp holes edges against the
direction of the cylinder rotation or the screen should be replaced. The
GM 170 can be fitted with numerous screens that are available with various
size holes to accommodate different material and grinding requirements.
A screen storage rack is provided on the left side of the mixer.
NOTE: If a screen is correctly installed, it should fit tight against the mill
throat plate and butt tightly against the mill frame hood sheet when the mill
screen cover is closed and securely latched.

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
the latches properly adjusted .
SUPPLEMENT HOPPER
The cover on the supplement hopper is spring-loaded to hold it in
either the open or closed position. A bag guard is provided to prevent
containers from being accidentally drawn into the transfer auger. A
flip-over bag breaker allows easy opening of supplement bags.
NOTE: Liquids, such as molasses, should not be poured into the
grinder-mixer.
