The mixer is made of stainless steel and is coupled with the planetary gear by a snap
closure. It rotates on its own axis and is moved by an electric motor at 2 fixed speeds in
a planetary motion around the bowl axis. Mixer and gear head move in opposite direc-
tions.
The mixing bowl consists of NIROSTA steel and can be removed from the working posi-
tion after lowering.
The contours of the mixer and mixing bowl are in accordance with the EN 196-1 standard
and guarantee a distance of 3.0 ± 1.0 mm between mixing bowl and mixer.
The distance in vertical height can be readjusted as described in section 6.9.
The electromechanical sand feed is made of steel plate. In the housing of the sand feed
there is an electromagnet that moves the locking plate via a piston rod. The locking plate
is secured by a spring and can be opened at a standstill or during low speed.
5.2 Electrical design
The supply voltage/frequency for the mixer can be 110-240 volts, 50-60 Hz.
The mains connection is made by a 2-pin Schuko plug, with potential equalisation.
The main switch, which separates the mixer from the mains, is located on the right side
of the mortar mixer.
1) Components in the rear of the mortar mixer
I/O board, power supply, frequency inverter with line filter, fuse
