■ MIXING CONCRETE AND MORTAR
Incline the drum as required. A more horizontal position gives a better mix with sticky mixes like mortar, without reducing the
capacity. Put in half the water and add sand and gravel. Add the cement and finally the rest of the water. Let the drum turn
for about 1 min. Longer than this will tend to centrifuge the materials. 1 shovel = about 4 litres, 1 wheelbarrow = about 80l.
■ MIX QUANTITIES
The mixes below were developed after tests carried out in partnership with CIMENTS LAFARGE. The table below gives an
average mix using the following components : ciment normal use 32.5, gravel about 25 mm stones, sand 25mm. grains, water.
Quantities may vary because of size/wetness
etc.
Reinforced concrete
Concrete
Base for tiling
Mortar
(1) The quantity of water varies with the wetness of the gravel/sand. (2) Final volume = usable quantity of concrete/mortar
produced. The above quantities are only approximate and we are not responsible for their accuracy.
■ ROUTINE MAINTENANCE
• Clean the inside of the drum
thoroughly after use;
incerease the life of the mixer. If using
a hose or a pressure cleaner, avoid
turning the water jet onto the motor.
• To clean the inside of the drum, use
some gravel and water.
• Grease the mixer at all greasing
points each week.
■ DRUM ADJUSTMENT
Check for wear in the friction washer
between the yolk and the drum by
checking for longtitudinal movement
of the drum. To take out excessive
play, unscrew the cap on the drum-
shaft, take off the split pin and tighten
the nut by 1/6th. of a turn. Check the
play and repeat the operation if
necessary. Refit the split pin and the
cap.
■ GREASING THE DRUMSHAFT
This operation should be carried out
every month if the mixer is used
regularly. (The other grease points
should also be filled regularly)
• Put the drum in its vertical position
with the cone uppermost.
• Undo the cap on the drum-shaft
• Take off the cap on the greasing
point between the yolk and the drum.
