Handling; Setting The Hammer Lift Height - HAVER & BOECKER W.S. TYLER Ro-Tap RX-29 Notice D'utilisation

4. Handling

Once the proper test sieves have been selected, they should be stacked (one on top of the
other) with the largest opening sieve on the top of the stack. A bottom pan should be added
under the smallest opening sieve to collect "fine" material passing through the last sieve. The
complete test sieve stack is placed on the sieve support plate (17) of the test sieve shaker.
During its installation the hammer should be turned aside. After the sieving material has been
filled, a sieve cover with a cork piece should be placed on top of the stack.
Adjust the sieve support plate by the sieve support clamp bar (18) in such a way that the
sieve cover (16) has top edge flush with the upper carrying plate (9). The sieve cover must
keep this height to make sure that the hammer drops from the right height to guaranty the
precision of the sieve analysis.

5. Setting the hammer lift height

The hammer has been pre-adjusted by the manufacturer. If the sieving result is not satisfying
the hammer setting should be re-adjusted. The hammer is adjusted in such a way, that it
touches the cork piece in the sieve cover (16) as shown in fig. 1.1.
NOTE: Prior to hammer adjustment, make sure cork in sieve cover is seated
firmly. Make sure sieve cover has top edge flush with upper carrying
plate.
Warning! Before opening the machine pull out the mains plug.
STEP 1 Remove pedestal cover.
STEP 2 Jog machine until hammer rises to maximum height or use a box wrench
on the hex head screw, located on top of the pedestal. Check height
with scales.
Set height to 1-5/16 ± 1/16" by loosening screw on coupling and
STEP 3
adjusting lift rod.
STEP 4 Tighten screw on coupling.
STEP 5 Replace pedestal cover.
