Aran APT Pressure Transfer System.
The Aran pressure
transfer system has been specifically developed to transfer particulate binders such as
cement and flyash from bulk storage silos or bulk bag to other storage or operating silos.
The heart of the
system is a dense phase pressure transfer system which receives batch quantities of cement
from the storage silos or other binder hopper or transfer station into a pressure vessel.
This system transfers the material under the pressure of a positive displacement
blower. The system can be extended to deal
with a number of input units and output. 
A stand alone Aran
APT system includes a logic controller (PLC) which can review the cement available in the
storage silos, and draw from each in rotation, or control the secondary loading system in
the case of a bulker bag unloader. It also can
review the needs of the receiving silo and deliver according to their requirements. It is programmed to continue to fill the silos
whilst being serviced until the silo is full, but can respond to an emergency call from
another plant with imminent shortage. When
supplied in conjunction with an Aran mixing plant, the primary management of the transfer
system is handled by the mixing plant control system with add on PLC and I/O components. A matching Vega guided microwave silo level
measuring probe is supplied for installation into each of the site silos for precise and
accurate control.
The standard kit
includes all necessary valves, control solenoids, fittings, and the like to set up a
single transfer system. Flexible sleeves and
clamps are included for connection between the source inlet pipes and those forming part
of the APT system are included.
Control valves and
components are preassembled, and factory tested.
The APT system is
assembled on a skid and tested in the factory. Site
assembly only involves connection with the input and output devices.
APT TRANSFER SYSTEM
APT-1.8; Basic Aran pressure transfer system kit set for one
input and one output. This consists of:
- APTV transfer vessel, (1.8 cubic metres
working volume) complete with air actuated close off valves for the cement inlet, the
vessel vent, the discharge line, the air inlet, and a bypass valve which diverts system
conveying air to the transfer line whilst the vessel is filling.
- APTB-02 Medium pressure blower set complete
with 37kW electric motor, starter, positive displacement blower, base frame, intake filter
silencer, and relief valve, all ready for connection by flexible rubber hose sleeves
- APTC Aran pressure transfer control and
management system complete with controller, I/O devices, cabinet, operator interface,
mimic panel showing system status, solenoid valves for the operation of all valves on the
transfer vessel and for operation of the input discharge valve.
- Total theoretical capacity of the system is
21m3/hr
- Installation instructions and circuits, and
operator manuals.
