INTRODUCTION
This manual has been prepared to make you
familiar with the proper operation, adjustment,
lubrication and service of your grinder mixer. Take
time to be careful and better understand the
efficient operation and care of your machine.
Whenever t
he terms “
Left
” and “
Right
” are used, it
should be understood to mean standing behind the
machine and facing the direction of forward travel.
Some pictorials are used to show guards, doors
and shields removed for easy identification.
Make sure that all guards, doors and shields are
in place before operating the machine. They are
for your protection.
The Art’s-Way JR Series Grinder Mixer is driven by
a PTO driveline of 30 HP to 100 HP tractors. (Figure
7, Detail A.) Using a tractor over 100 HP is not
recommended. It is factory available with a 540
RPM drive.
Hammer mill respective speed should be
maintained as the hammer mill cylinder operates
best at 2800 to 3000 RPM. (Figure 7, Detail B.)
Hammer mill cylinder must not exceed 3000 PRM.
CAUTION: NEVER OPERATE A 540 RPM
PROCESSOR WITH A 1000 RPM
TRACTOR.
Before operating your grinder mixer, select and
install the screen size desired. Sizes are available
from 1/8 to 2 inch openings. For screen selection
guidelines, refer to OPERATION OF GRINDER
MIXER
All types of grain can be ground with the hammer
mill. Hay can be ground with a minimum of 1/3
mixer of grain. Material is fed into the hammer mill
where it is ground until it can pass through the
screen size selected. From the hammer mill, the
material is augered into the mixing tank. (Figure 7,
Detail C.) A suction fan takes air pressure out of the
hammer mill housing and delivers feed fines into
the dust collector. (Figure 7, Detail D.) The fines are
separated and then dropped into the mill to mixer
auger.
If supplement is to be added to the ration, a hopper
with a sack cutter is located at the right rear of the
mixing tank. (Figure 7, Detail E
– Supplement
Auger.) The best mixing will result if the supplement
is added before grinding.
The ground feed is mixed continuously until the
tractor PTO is disengaged.
The unloading auger pivots at the left rear of the
mixing tank and can swing 180 degrees on the
grinder mixer in a horizontal arc. (Figure 7, Detail
F.) It can also swing in a vertical arc to the limit of
the lift cylinder. Unloading rates up to 30 bushels
per minute can be obtained depending upon
position of the discharge and the type of material
processed.
Viewing windows (4-JR50 and 6-JR75) are located
on the sides of the mixing tank to observe the feed
