2017-5-23 When this feeder was first operated in a cement plant, it was found necessary to modify the design to accommodate highly abrasive silica-bearing material. Since then, plant managers report that their Posimetric feeder has only required occasional visual inspec-tion, adding that they’ve never found anything that required attention.

2021-6-18 A basic vibratory feeder consists of a trough supported by springs, hinged links, or other force-dampening mechanical components. These isolate the vibratory feeder from the structural members of the building which can cause unwanted reaction forces. Attached to the trough is a drive unit that produces high frequency, low amplitude oscillations.

2021-3-25 the feed end of the feeder tray. The hopper takes the brunt of the dump which saves wear and tear on the feeder tray. Additionally, the hopper makes first contact with the product which reduces wear and tear on the feeder tray. Further, both the hopper and feeder tray can be lined with abrasion-resistant material, some of which can provide

2021-6-18 The natural frequency feeder takes advantage of the natural magnification of the oscillations which occurs when the system operates at a speed near its natural frequency or resonance condition. Because of this, a relatively small force is required to generate the necessary vibratory forces.
