This vibrating feeder design provides linear control from zero to maximum feed rate. Variable Force counterweight control alters the exciting force by varying only the counterweight effect rather than the motor speed. As air or hydraulic pressure signal varies from zero to maximum, the unbalanced forces vary proportionally.
Loss-in-weight feeding. A typical LIW feeder achieves rate control by weighing the entire feeder, hopper, and the material contained in it (see . Figure 1). The speed of the metering device is controlled to result in a per-unit-time loss of system weight equal to the feed rate.
The PFD-401 Series is a rotating disk feeder conceived to feed various types of fee flowing powder at constant feed rate. The PFD-401 can be used for a powder size range from 10pm up to 300pm. Our Ultrasonic vibration device which is standard on all Tekna Powder Feeders provides the advantage of pasting powder feeding without problems.
When the powder level is above four feet, the bridges and arches are naturally corrected. However, the area below four feet requires the direct operation of Sodimate's Mechanical Bin Activator. It prevents bridging or arching with a set of flexible rotating blades that unfold inside the powder, from the centerline to the cone wall.
Thanks to a controlled vibration, the bin activator guarantees a continuous flow of the material into silos and hoppers Facilitating powder extraction under silos Composed of a steel or stainless steel cone, weld-free construction, integrated flange joint on top and bottom, silo connection brackets, and one or two electric vibrators .

An important accessory used with Gimat's powder feeders are the bin dischargers, used below hoppers and tanks for the discharge of powder, milled and mixed substances.. These bin dischargers become necessary and are particularly advantageous in the presence of products that clog with low fluidity, or if the installation is in a confined space.
A common use of a vibrating feeder is in filling applications where the electromagnetic drive operates at maximum amplitude to rapidly fill a weighed container. As the target weight is reached, the feed rate is slowed to a trickle until the …
Bin Activators are equipment conically shaped that aid dry bulk material flow from storage silos, or hoppers. Polimak Bin Activators are used in several industrial applications to efficiently discharge dry solid materials in powder or granular form from upstream equipment, thereby, reducing bulk material bridging or ratholing while promoting mass flow.
