Handling heavy-flowing bulk materials places high demands on accuracy and reliability, especially when processing small quantities. In tests conducted by AMW, the ZD 5 FB feeding unit from Three-Tec proved to be particularly efficient.
For small quantities or feeding flows of less than 100 grams per hour, Three-Tec offers a reliable feeding solution with the ZD 5 FB flat-tray feeder. The smallest twin-screw flat-tray feeding unit in our range is ideal for feeding poorly flowing powders. With a screw diameter of just 5 mm, minimum feeding flows of 5 grams per hour can be achieved.
A high feeding consistency of the feeding device used is crucial for an accurate, continuous feeding result. If a high feeding consistency can already be achieved with a feeding device in volumetric feeding operation and without discharge or flow aids, only slight control interventions are required in gravimetric operation, which considerably increases the feeding accuracy.
AMW GmbH was looking for a feeding solution for quantities of less than 50 grams per hour. In tests with PLGA polymer powder using three feeding devices from different suppliers, AMW recorded three measuring points for each of three motor control commands. The feeding devices were operated purely volumetrically for the tests, i.e. without weight-based control.
The test results make it clear: The ZD 5 FB flat-tray feeder from Three-Tec outperformed other models in terms of low dispersion, making it the optimal choice for the most precise dispensing requirements.
