GraviMaster 2704 |
 |
Blend feeding |
| With blend feeding the throughput of each component is measured with a
GraviMaster and the blend controlled via the feeders according to the
throughput settings. The conveyance control can be integrated in the
GraviMaster. Since feeding is arranged in a modular form the process-specific functions are allocated to the first components. Alternatively, the individual instruments can also be connected via a fieldbus interface to a supervisory PLC. |
Self-coloring with gravimetric metering |
| An important function with feeding is the self-coloring directly on the
extruder of neutral material with masterbatch. Masterbatch is fed in at the side into the main stream of the neutral material. The setpoint takes into consideration the measured throughput of the main components, or it is calculated from the screw speed and the specific characteristics of the extruder. With weight-per-meter control masterbatch feeding can be integrated or supplemented by an additional instrument. |
