Vibrating feeder ПЭВ 500/350х1200-50

Electromagnetic vibrating feeder, light feeders, open tray · drive ВЭМ-Л3

The ПЭВ 500/350х1200-50 is a light-duty electromagnetic feeder with an open trough 500 mm wide and 1200 mm long. Maximum throughput is 50 m³/h with a lump size up to 90 mm — among the models in this group rated for that flow, this one has the shortest trough. The ВЭМ-Л3 drive sits underneath, supply is 380 V, 50 Hz, and coil current does not exceed 7 A. Mass excluding vibration isolators and the control unit is 275 kg.

Where it is used

Discharging crushed stone or gravel up to 90 mm from under a bin onto a short conveyor where transfer height is tight and a long trough simply will not fit: overall length stays within 1510 mm.
Feeding sand and screenings into a mixing station on an aggregates line — 50 m³/h keeps the line supplied, while coil voltage adjustable from 0 to 300 V lets you dial the flow down to suit a particular mix.
Topping up a crusher or screen with a steady stream instead of the surge discharges that make equipment run in fits and starts.
Replacing a worn feeder in an existing frame where the mounting length is fixed but the required flow stays at 50 m³/h.

How it differs from neighbouring models

ПЭВ 500/300х1600-30 — та же ширина лотка 500 мм, но длина 1600 мм и производительность 30 м³/ч — длиннее путь материала при меньшем потоке
ПЭВ 500/450х1600-50 — та же производительность 50 м³/ч на лотке 1600 мм, привод ВЭМ-Л4 и масса 410 кг вместо 275 кг
ПЭВ 360/215х1250-25 — сопоставимая длина лотка при ширине 360 мм и потоке 25 м³/ч — вариант, когда 50 м³/ч избыточны

Questions and answers

Why does this model deliver 50 m³/h when longer feeders of the same width deliver 30?

Throughput is set by the flow cross-section and the drive regime, not by trough length. The ПЭВ 500/350х1200-50 uses a ВЭМ-Л3 drive with coil current up to 7 A, while longer models of the same width are rated for 30 m³/h. Trough length governs how far the material has to be carried out from under the bin.

Can it run below 50 m³/h?

Yes. Coil voltage is adjustable from 0 to 300 V by a ШУВ cabinet or БУВ unit, so output varies smoothly from zero to maximum. The 50 m³/h figure is the maximum, measured on dry sand with a bulk density of 1.52 kg/dm³.

What does the 275 kg mass include?

That is the feeder alone, without vibration isolators or a control unit. Their mass and mounting dimensions have to be accounted for separately when sizing the support frame; feeder dimensions do not exceed 1510×720×770 mm.
