|Batching / Filling
|The system consists of storage
hoppers where the raw materials are stored for batching
/ bagging. A suitable feeding arrangement is fitted to
each storage hopper for feeding the material. The feeding
arrangement is capable of fast and slow feeding as per
the control outputs. A weigh hopper is provided just below
the storage hoppers for weighing the raw material fed
from the storage hoppers. The weigh hopper is provided
with a gate arrangement for holding and discharging the
|In a batching system the output
from the weigh hopper is sent to the production process
either by gravity or by use of a conveyor. In a filling
/ bagging system the output from the weigh hopper is fed
into a container or a bag by gravity. A special mechanical
arrangement for holding the container or clamping the
bag is also provided.
|The load cell signals are fed
to an Electronic controller fitted in a control panel.
The controller displays the weight of material in the
weigh hopper. All batching / bagging parameters are entered
through the front panel keys.
|To start the batching / bagging
operation, the operator has to put the system into Auto
mode. The coarse output is given for fast feeding till
the weight in the hopper reaches coarse set weight. Then
the Fine output is given for slow feeding till the final
set point is reached. The above process is repeated for
all the raw materials.
|On sensing a discharge input,
the system discharges the material from the weigh hopper.
Once the material is fully discharged the system is ready
for another batching / baggin operation.
|The total number of batches
/ bags and the total quantity batched / bagged are all
stored in the controller and displayed by pressing the
FUNC key. These values can be reset by the operator as
and when required.
