Dry mortar plant 5475

Function description:

From the sand warehouse, the wet sand is transported via the belt conveyor ( 01 ) to the sand silo ( 02 ). From the sand silo, the wet sand is transported by the belt conveyor ( 03 ) to the drum dryer ( 04 ).

During sand drying, sand and dust particles are sucked through a double cyclone ( 05 ) and deposited on the underlying belt conveyor ( 06 ).

When the sand drying process is complete, the dried sand is discharged to the closed belt conveyor ( 06 ), which transports it to the Elevator Lock ( 07 ). The elevator lock's damper system makes it possible to remove the dried sand via a screw conveyor ( 08 ), or to pass the sand to the Bucket Elevator ( 09 ).

The bucket elevator transports the sand to the Auger Conveyor ( 10 ), which transfers the sand to the Screen ( 11 ).

The screen is mounted on the Silo ( 12 ), which is divided into six compartments, each of which can contain sand of a given grain size. Each silo compartment has an outlet to a Screw Conveyor ( 13 ) at the bottom.

The six auger conveyors ( 13 ) can each transport the desired sand quality from the silo into the weighing cone ( 14 ).

From the weighing cone it is possible to remove weighed, sieved sand via a bypass damper and a screw conveyor, or to deliver the sand to the Mixer ( 15 ).

Before it is started, the mixer will be able to receive weighed aggregate materials from the three raw material silos ( 16 ), the two Big bag emptying stations ( 17 ) and the two Micro dosers ( 18 ).

The transfer of aggregates takes place with screw conveyors.

When the desired recipe mixture is mixed, the mixture is delivered to the batch silo below the mixer.

The batch silo can now release the finished mixture to the Pneumatic sending system ( 19 ), which can forward the mixture to the Finished Goods Silos ( 20 ), Big Bag Filling Station ( 21 ), or directly to the Receiving Container ( 22 ) , which can then empty the mixture directly to the Hopper ( 23 ) before the loading bellows.

Ready-mixes from the Finished Goods Silos ( 20 ) are transported by screw conveyors ( 25 ) directly to the Receiving Bin ( 23 ).

Loading of finished products is carried out via the Loading Bellows ( 24 ), which fills directly into the transportable Mortar Silo ( 26 ).

The system is delivered with 2 operator panels with 7” touchscreen and PC with WinCC.

The control system is a Siemens PLC control, programmed in Siemens S7 and with a touch screen for easy operation.
