The conveying system
PFT SILOMAT E
is a pneumatic, fully automatic conveying
system for transporting ready-mix dry mortar from the silo / container to the cleaning
machine.
Please observe the processing guidelines of the material manufacturer
.
The machine consists of carryable single components of small, handy dimensions and
light weight that allow fast, convenient transport.
The following aspects must be observed for operation:
1.
Connection worksite power – control box
2.
Connection control box – level sensor
3.
Connection control box – motor and drive
4.
Connection control box – vibrator
5.
Connection compressor – conveying container
6.
Connection conveying container – cleaning machine
Operating sequence
When the level sensor of the cleaning machine reports “Empty”, the flap opens
(“Open” position) and the conveying container is filled with approx. 55 l of dry mortar
while the silo butterfly valve is open. The vibrator runs at the same time, to support the
flow of mortar from the silo / container.
When the fill time has passed, the flap closes again (“Closed” position). The convey-
ing container is now sealed pressure-tight to the silo / container.
Now the compressor begins to work and blows air through the emulgator filter into the
conveying container. In this way, the mortar is aerated and pressed through the ex-
traction connection of the conveying container into the conveying line and on to the
cleaning machine. Pressure is built up in the conveying line that is monitored with a
safety switch. If it falls below a set value, that means that conveying container and line
are empty. The system completes the conveying cycle and shuts down. As soon as
there is a new signal by the level sensor at the control box of the SILOMAT unit, a
new conveying cycle is started.
The distribution of air can be controlled by hand using the bypass at the conveying
container. In this way the system can be adapted, depending on the mortar (specific
weight).
