The belt weigh feeder extracts a product from a storage hopper through the constant cross-section and according to a fixed reference flow-rate (set point), adjusts the extracted volume by varying the belt speed in such a way as to keep a constant weighed flow-rate.
The DLV belt weigh feeder was designed especially for poor flowing and sticky materials. The belt conveyor is extended to incorporate the “buffer hopper” with vertical anti-sticky walls where the material is slowed down and de-aerated. This weigh feeders is used in:
