| 摘要 |
<p>The invention relates to apparatus (1) for controlling substantially vertical discharge of flowable material such as a powder or other particulate or granular material (2), comprising a discharge opening (3) near a lower end (in use and as shown) thereof, flow control means (4) adapted to be mounted internally of the discharge opening (3) for the flowable material (2) and to form with that opening (3) a flow path (5) for material through the opening (3), a load cell (6) adapted to monitor the weight of material, and an electronic controller (7) connected electronically with the load cell (6), the arrangement being such that a signal from the load cell (6) is interpreted by the controller (7) to control the flow control means (4) and to maintain a desired discharge for a batch of material to be discharged through the opening (3).</p> |
