| Application | |||||||||
| Liquid loss-in-weight feeder is designed to provide gravimetric feeding of | |||||||||
| liquid materials.It is most frequently applied in continuous processes,such as | |||||||||
| feeding a compounding extruder where difficult flowing liquids must be | |||||||||
| metered at precise feed rates. These liquids are often waxy or viscous and | |||||||||
| must be heated to flow properly. | |||||||||
| Characteristics | |||||||||
| ★ consists of a storage tank mounted on a high accuracy scale designed for | |||||||||
| industrial applications. | |||||||||
| ★ The liquid is metered by a pump positioned off the scale so that only the | |||||||||
| liquid and its container are weighed. | |||||||||
| ★If the temperature of the liquid to be fed must be maintained at a constant | |||||||||
| level, a strip heater or transfer heater using oil or water may be employed. | |||||||||
| ★ When using a strip heater, temperature is controlled by a thermostat and a | |||||||||
| safety thermostat. An insulating jacket is placed over the strip heater. The | |||||||||
| connecting line is also heated and thermally insulated. | |||||||||
| ★ When using heat transfer, the tank is double-walled and filled with oil or | |||||||||
| water. | |||||||||
| ★ The sophisticated load cell provides split-second, high precision weighing | |||||||||
| in the milligram range and is specially designed for harsh industrial | |||||||||
| environments. | |||||||||
| ★ Liquid feeders are easily integrated with gravimetric bulk solids feeders. | |||||||||
| The gravimetric controller and operation interface allow for individual unit | |||||||||
| and recipe control. Each feeder has its own control board. Connection | |||||||||
| between control boards and operation interface is supported by industrial | |||||||||
| protocol. | |||||||||
