2. Loosen the tension skirts, raise the skirts and lock them in the “up”
position.
3. Loosen the set screws located at both sides and ends of the machine.
4. Pull out the screen elements and ball deck together. The ball deck
sections are bolted together as shown on page 20. If there is insufficient
clearance behind the machine, they will have to be unbolted as each
section is pulled clear of the machine. Note that finer mesh screens will
have overlapping seal plates at the joints between each section and they
will have to be removed first before each screen element is removed.
Screens removed out of the Top of the Machine
If there is insufficient room to remove the screens at either end of the machine,
then the screens and ball decks must be removed through the top. To do this:
1. Remove any inlet connection sleeves.
2. Remove the dust cover.
3. Loosen and remove all the screen tension skirts.
4. Remove the screen element.
5. Loosen the set screws at both sides and ends of the machine and remove
the ball deck.
6. Repeat the above for any additional screen decks below.
For very fine, delicate screen elements it is recommended that the ball decks be
removed as well as the screen elements, so that the screens can be placed on
top of the ball decks for reinsertion into the machine. This will minimize the
potential for damaging the screen element.
SCREEN REPLACEMENT
One-Piece Screens
If one-piece screens have been removed from either end of the machine then the
screens can simply be slid back into position. Make sure that the tension skirts
are in the ‘up’ position using the supplied tool.
Make sure that the leading edge of the screen is not damaged as it is pushed
into position. This can easily be avoided if a pair of screen-length plastic pipes
about 1” (25mm) in diameter are first laid down on top of the ball deck. The
