4. DESCRIPTION OF MORTAR MIXER OPERATION
- THE CAM SCREW mortar mixer is designed for use
in building sites, for pumping, injecting or spraying all
wet or pre-mixed materials, compatible with this type of
machinery: liquid cement, adhesives, finishing products,
levelling products, waterproofing, finishing colours,
grouting, traditional mortars or pre-mixed products,
plasters with a lime/cement base or gypsum, fire-proof
insulants etc.
4.1 DESCRIPTION OF MORTAR MIXER (see fig.1)
The mortar mixer comprises a wheeled frame (ref. N), which
supports a hopper (ref. 6) with grid (ref. 5), an electrical panel
(ref.7), a gearmotor (ref. 8), which, by means of a mixer (ref.
9) activates a cam screw pump (ref. 10/11) that conveys the
material via a rubber hose to the jet (ref. 3).
If the material is sprayed, air is also delivered to the jet by
means of a compressor (optional).
The mortar mixer can be controlled by means of: pneumatic
control, electrical via cable (radio control-optional).
The flow rate is controlled by means of the buttons (+) and (-)
on the control panel.
The flow rate is shown (0=min, 100=max) on the electrical
panel display. The mortar mixer can be combined with various

accessories, as described in paragraph 4.2.
4.2 DESCRIPTION OF MAIN ACCESSORIES REQUIRED
FOR THE RANGE OF APPLICATIONS
SMALL 50 is undoubtedly the smallest and most versatile pump
available. There are manifold applications in which this pump
represents the ideal solution in terms of operation and speed. By
the simple addition or replacement of an accessory, SMALL 50
can be adapted to diverse requirements. For this reason, it is
important to be aware of the wide range of accessories available,
to enable full exploitation of the potential of this machine.
IMER INTERNATIONAL is available, through their dealers and
authorised service centres to evaluate your requirements and
find the ideal solution.
Commonly used optional accessories (see fig.1):
- IMER VIBRO - SCREEN code no. 1107548
- This accessory replaces the hopper grid and is
therefore equipped with a safety sensor.
It must be used when the material is to be mixed on site with
collection of aggregate from a loose storage deposit: in this
case some aggregate may have a larger particle size than
admissible values, which could obstruct the spray outlet or cause
premature wear of the stator
After removing the hopper grid (ref.5), position the screen on
the hopper (ref. 6) and make the electrical connection with the
machine s electrical panel (fig.5,ref. 12), fitted with the vibrator
on/off control.
Operation: after positioning and connecting the machine, and
before pouring the material into the hopper, set the main switch
to ON to start up the vibrator. Pour in the required material and on
completion turn the switch to OFF, removing any residue trapped
in the screen.
- HOPPER COVER (see fig.2)
IMER code no.1107513
- This accessory replaces the hopper grid and is
therefore equipped with a safety sensor.
It is used to close the hopper and isolate the contents from air
and possible impurities: finishing colour, finishing mortar etc. This
delays drying of the materials thus enabling prolonged storage
time in the hopper.
Position at the top of the hopper (ref. 5) with or without the
hopper grid (ref. 6),
- IMER BAG SPLITTER code no.1107511
It is used to speed up and optimise emptying of the bags containing
the wet material ready to use (e.g. the most common lime-based
finishing mortar).
It features simple connection to the machine. If necessary the
roller crushing pressure can be adjusted as required: loosen the
screws to reduce and tighten to increase.
Intuitive operation: lay out a bag of material lengthwise on the
hopper grid, move the protruding flap of the sack towards the
rollers (ref. 4b), use the right hand to slightly turn the rollers
clockwise by means of the handwheel (ref. 4a), so that the bag
is trapped between the rollers. Use a cutter to open the sack at
the other end, and turn the rollers until the bag is totally emptied.
The material is now in the hopper ready to be pumped.
