sequence, weighing each material after each dispense confirming material required before moving
on to the next material.
The complete batch is released into the mixing
chamber, and mixed with the previous batch to
ensure a homogenous mix.
Material blending is controlled by a level sensor
mounted in the upper part of the mix chamber.
When the sensor is covered the blender will not
dispense any further batches. The level of material in the mix chamber is critical to good mixing.
As material in the mix chamber is consumed the
sensor is uncovered and then the blender then
commences the next cycle.
For special functions these can be easily accessed
and set via the password protected keypad.
There is audible alarm and strobe light with silence function, should a batch be incomplete.
Setup and Operation reports can be printed direct
to a USB key.
Data is also available allowing remote access and
monitoring to download settings and check job
progress.
Integration to other control or ERP systems can
be made by leading fieldbuses or OPC interfaces.
