Concrete Spraying Machine
– SSB 02.1

The bottom sealing plate is fixed on the frame on which the dozing drum is rested
as well as the exhauster and bottom exhaust.
The Machine feeder is complimented by vibrator for acceleration of filling of the
transported mix, and a sifter.
The Machine head is mounted on by four tightening bolts serving to control
(adjust) thrust of the sealing plates to the dozing drum.
The exhausts with filtration bags serve to capture air remains and dusty particles
from the dozing drum cylinders.
The air distribution comprises the main intake and four controlling cocks. The
main intake is provided with a controlling cock and quick coupler for connection
of the pressured air DN 50 hose. The controlling cocks serve to intake air to the
Machine head (primary (upper) air), to the exhauster (secondary (bottom) air), to
clean the Machine and control the pneumatic vibrator. The controlling cocks for
the air intake to the head (primary (upper) air) and to the exhauster (secondary
(bottom) air) are equipped with manometers.
The central lubrication system comprises the lubricating equipment and tank,
controlling automatic system, outputs and pipe. The lubrication system transports
the lubricant (grease) or oil between the areas of sealing and wearing plates and so
avoids their excessive friction.
The control of the Machine is concentrated on the electric motor cover side. The
compressed air intake is situated on the cover side.
The whole Machine is alternatively placed on a solid frame, rail undercarriage or
bantam wheels.
Working Principle
The shotcreting machine SSB 02 works on the principle of pneumatic transport.
Dry-gunning
The dry mixture for spraying or transportation is poured in the machine and
smoothly fills the cylinders of the rotor below the hopper. To fill a mixture into
the rotor more easily, a vibrator and a rippling are fitted in the hopper.
The rotating movement of the rotor moves the mixture along by 180 degrees in
the clockwise direction. The mixture is thus blown out from individual cylinders
of the rotor into transport hoses. As the mix passes through the blower into the
transport hoses, lower pressure air is added to enhance the continuous flow of the
material in hoses. The hoses are equipped with the spraying nozzles at the end,
into which the mixing water is fed at the same time to wet the transported mixture.
The required wetting of the mixture is controlled with the supply cock.
