Functional description and design features
PSP silos are complete systems for picking up, storing and discharging
conveyed goods. They essentially consist of
of the silo body with supporting structure, a special silo floor with
discharge system
(sliding frame and discharge and pre-pressing screw for feeding a
thick matter pump). Depending on the
Depending on the customised system, assemblies such as an assembly
platform, insulation/heating or instrumentation are added.

Silo dimensions (lxw): 5,500 x 3,500 mm
Cylinder stroke: 800 mm
Weight of the frame: 1.2 tonnes
The silo discharge system consists of
- Discharge sliding frame made of special profile S 355, in two or
three sections depending on size for transport and easy assembly
with bolted connection.
- Double-acting hydraulic cylinder, short design, with coupling rod
(multiple chrome-plated), clamping coupling,
clamping flange and driver.
- Spherical cap for aligning the hydraulic cylinder during
assembly.
- Special seals and guide bands as well as contact protection for
coupling rod.
- Two non-contact limit switches on the hydraulic cylinder for stroke
reversal.
- Blockage monitoring.
- Automatic centralised grease lubrication via the thick matter pump
lubrication system
- Electrical and hydraulic controls.
Safety devices:
- The proper functioning of the discharge sliding frame is monitored
by non-contact limit switches and control of the lifting time.
and control of the lifting time. If the set lifting time is exceeded,
the lift reverses automatically and a fault signal is issued
(without interrupting operation).
- The hydraulic circuit is pressure-monitored. In the event of a
blockage of the discharge sliding frame, the stroke is reversed
automatically.
stroke reversal takes place automatically.
When planning, please consider the space required for the hydraulic
cylinder outside the silo as well as a free space for removal.

A gate valve can be used to shut off parts of a system for a variety
of reasons. The
gate valve is installed either under a silo, bunker etc. in the inlet
of the Putzmeister pump.
- This is advantageous for carrying out any maintenance work in the
pump hopper when the silo is full.
- The valve blade is opened or closed manually.
- The open/closed status is monitored by proximity switches.
