Heavy feeders, bottom-mounted drive

Heavy PEVF feeders with a bottom-mounted drive are the largest and most powerful group in the catalog: 17 sizes with a capacity of 60 to 300 m³/h at a tray width of 700 to 1500 mm. The feeder is sized to receive material directly from a hopper or below a screen in a crushing-and-screening plant, so stable operation under the static load of coarse lump material matters more than metering precision here — the maximum lump size on the largest models in the range reaches 400 mm.

The feeder's own mass runs from 1150 to 2600 kg depending on the size, and the drive is an electromagnetic VEM-T1-T4 — the same operating principle as the light line, but rated for a multiple-times-larger tray-plus-material mass. The drive sits below the tray, which is the base, most common layout for heavy feeders and requires no extra space above the tray.

This design is used at mining and processing plants, metallurgical works, and building-materials production — anywhere ore, agglomerate, crushed stone, or other coarse lump material needs to be drawn from under a hopper as an even, adjustable-capacity flow. See the industry pages for mining, metallurgy, and building materials for more on this application.

Because of the large tray-plus-material mass, PEVF vibration isolators are sized individually for the specific model and the batch weight being processed — it's a separate item in the technical specification for the supporting structure, agreed alongside the order. The electrical side is the same 380 V, 50 Hz supply through a control unit as on the light line.

If the space below the tray is limited — for example when mounting the feeder above a conveyor or in a tight workshop layout — consider a PEVVF design with a top-mounted drive instead.
