next to the protocol name, e.g. Shale Rock(MOD).

6.0 LOADING THE GRINDING JAR

Before using a planetary mill grinding container, check to make sure that it is clean and that the
O-ring is in good condition. The sample should be crushed to proper feed size before it is
loaded into the container, approx. ¼" to ½" for the steel containers.
Place the sample in the grinding container FIRST, then the grinding balls and apply the cover
(firmly seated). Do not overload the grinding container. Recommended sample amounts for
500 mL jar (100 g to 225 g) and for 250 mL jar (50 g to 100 g). Additional information on
grinding and mixing is in Section 9.1.
7.0 LOCKING THE GRINDING JAR IN THE CLAMP
Lock Clamp Assembly
before running unit
The clamp locking knob is the most critical component of the Planetary Mill, as it must be
carefully adjusted to hold the jar firmly in place. The rotation motion of the clamp is extremely
vigorous. The jar must be held securely in the clamp during operation to prevent damage and
leakage.
The clamp base has two different size pins, designed to specifically fit in the two holes on the
bottom of the jar. To place a jar in the clamp, loosen the locking tab on the threaded shaft, and
unscrew the locking knob with a few turns (counterclockwise). Rotate the moveable arm
clockwise (downwards) unclasping it from the Y-cross bar, lift the locking knob assembly
upwards, as shown in Figure 11. When placing the jar in the clamp make sure the pins fit in the
proper holes. Once the jar is seated in the clamp base it should not be able to twist.
To lock the jar in the clamp, rotate the moveable arm counterclockwise (upwards) and push
down the locking knob to fit (clasp) the Y-cross bar inside the arm opening (Figure 12). Turn the
locking knob clockwise to secure the jar. Tighten the locking tab by turning clockwise.
