The shot cage (Appendix diagram No. 119) is like the blast wheel – a pure wear & tear part
and must be checked regularly. Two different kinds of wear & tear on the cage are possible.
The window in the cage has a width of 30 mm. Change the cage if this width is more than 33
mm. The second type of wear & tear is the decrease in the thickness of the cage wall itself.
Change the cage before a hole appears. If the blast wheel and cage are in a good condition
replace the parts using the opposite direction to that described above.
5.4 Wear & tear on the linings
The blast chamber and a large part of the reclaim chamber are protected by linings. These
prevent the machine from destroying itself. The linings must be changed if the thickness is
less than one third of the original thickness in any one place. The most wear & tear happens
to the side (Appendix diagram No. 1) and top linings (Appendix diagram No. 3) of the blast
chamber. The thickness of these linings is 10 mm. Should the wear & tear be more than 6
mm they must be changed. If they are changed too late, the machine will blast a hole in its
frame in a short time.
Changing the linings:
On both sides of the MODUL 200
®
are the side covers (Appendix diagram No. 71 and 73)
for the reclaim chamber and blast chamber. Remove the side covers by loosening the screws.
The side linings can now be easily removed. On the upper end of the blast chamber are two
screws directly under the turbine motor. Loosen the nuts of these screws and turn them out
by 8 mm. The top lining can now be removed. If this proves difficult, tap gently, but firmly
on both sides with a hammer. The motion of the hammer will remove trapped dust and shot
which may hinder removal of the linings.
The front and back linings of the blast and reclaim chambers are each secured by four (vive)
nuts on the outside of the chambers. Remove the blast wheel (Refer to “wear & tear on the
blast wheel and shot cage”). Loosen the four (vive) nuts and remove the linings. The
installation of the new linings is the reverse procedure to removing them. The lifetime of the
linings should normally be 200 hours. Again, a precise figure cannot be given for the same
reasons described for the blast wheel – i.e. depending on the application.
5.5 Wear & tear on the shot stop in the separator
On the inner side of the shot compartment lid in the separator is the shot stop (Appendix
diagram No. 161). This takes away the energy of the high-speed rebounding shot, thus
preventing the destruction of the shot compartment. It also prevents the dust collector from
sucking shot out of the machine. The shot stop should be regularly checked. Changing the
shot stop is easily done by removing the two screws on the shot compartment lid.
5.6 Belt drive
The belt drive is made to last at least 500 hours – but only if it is tensioned correctly. To
check the tension, remove the belt drive safety cover (Appendix diagram No. 187). It
shouldn’t be possible to move the belt (Appendix diagram No. 97) more than half a cm in
each direction halfway between the pulleys. If it is too loose, adjust the tension by loosening
the four screws which hold the turbine motor (Appendix diagram No. 91). On the upper side
