Wet-gunning
When the concrete mixture is applied in so-called wet method, the hopper is filled
in with the prepared wet mix. In principle, the mix passes through the machine in
the same way as when spraying the dry mixture. A hose for addition of chemical
additives (e. g. accelerating admixture) is taken from the external dosing pump to
the spraying nozzle instead of mixing water.
Drive and Output Control
The Machine is propelled by electric motor.
I.
Two-speed Electric Motor (DUO)
The machine is propelled by two-speed electric motor. The motor is fitted with a
stepped pulley and connected by one V-belt with the slide-on gearbox, which is keyed
by a hollow output shaft to the shaft of the bearing part of the dosing drum.
The machine output (rotor speed) is controlled by two-position switch. The motor runs
on 4 or 6 poles.
II.
Electric Motor with a Speed Variator (COM-V)
The electric motor is fitted with speed variator gearbox. It is connected to the slipping
gearbox by V-belt, and the gearbox is keyed to the bearing part of the dozing drum
with an output hollow shaft. The output is changes by means of the speed variator.
