MASTER plastering machine
18
Material consistency
too liquid or varies
irregularly.
Insufficient feed of dry
material.
Too much water flow.
Material gate is not open or
not completely open.
The mixing chamber
opening is obstructed.
The breather is obstructed.
The mixer has got material
stuck.
Fill in with dry material the material deposit (the
dry material level must never be under the shaft
level).
Regulate water slowly, reducing it.
Open completely the material gate.
Clean the way between the material deposit and
the mixing tube.
Stop the machine from the main switch, open
horizontally the mixing tube and clean the
breather of the material deposit and the mixing
tube.
Stop the machine from the main switch, open
horizontally the head engine, take the mixer out,
clean it, and take it out and in again.
The material comes
out regularly with too
thick or too thin
consistency.
The stator pressure is not
regulated correctly.
With readjustable stators, the best stator pressure
is regulated as follows:
a) Fill in with water up to 10 cm. The clean
mixing chamber and dismantle the water hose.
b) Join to the stator outlet the hydraulic pressure
checker with the evacuation key open, and
empty the air in by starting that stator shortly.
Close the evacuation key.
c) Start again and shortly the pump. For gypsum
rendering works and 10 mts. material hose DN
25, the manometer must indicate 25 bar
approximately.
d) If the 25 bar is not reached, fasten slightly and
evenly the stator screws and repeat pressure
test.
e) When using longer material hoses, a higher
pressure is needed (1 more bar per metre) up
to 35 bar maximum.
f) For materials made of cement and lime we can
have from 3 to 8 bar.
