Vibrating conveyors transport materials using directional micro-vibrations based on the micro-propulsion principle. They are used in many ways for feeding and mete ring tasks to transport bulk material and parts, particularly under abrasive, dusty conditions.

The directional sinusoidal vibrations of the vibration generator cause the same sinusoidal motion in the vibratory conveyor trough. The direction of these vibrations is ascending between 20 and 40 degrees to the horizontal basic line.

The components of force produced by the vibration generator must of course be present along the same totallength of the conveyor to ensure that identical vibrational amplitude and conveying speed exists at all points of the conveyor trough.

With the exception of the vibration generator, vibratory conveyors have no moving parts and are largely maintenance free. They are fixed to the supporting construction by means of elastic anti-vibration springs.

The vibration generators work as electrical unbalance motors on 3-phase current (electrodynamic drive) or as electro-magnetic vibrators on phase shifted 1-phase AC. The frequency of vibration is usually 60 Hz (50 Hz). Unbalance drives usually operate at a fixed, constant amplitude (unbalance force) . Modern unbalance drives can however be "controlled" using a fre­quency converter, i.e. the amplitude can be varied infinitely. Electro-magnetic drives on the other hand are fully controllable, i.e. the vibration force energy component is continuously variable by phase shifting (half wave rectification with phase control using thyristors).

All types of loading!unloading vibratory conveyors with rectangular or trapezoidal conveying trough , in standard sizes or in large special designs with abrasion resistant vulcolan (polyurethan) or vulcanised rubber trough liner. Conveyors made entirely of stainless steel are also available (304, 316) . All types can be supplied with either twin unbalance or electro-magnetic drives for vibration isolated suspension or installation (electrodynamic or electromagnetic). For special purposes vibrating conveyors can be supplied with heat resistant liner on air scoops with expansion compensation or with a flanged heat resistant outlet spout. In addition, dust-proof covers can be provided including round or oval intake and output ports. All conveyor troughs are designed and con­structed to withstand the effects of vibration. Vibration tube conveyors with twin unbalance or electro-magnetic drives can be supplied for special purposes. We can deliver any size of vibrating con­veyors from the smallest, most compact discharge conveyor through to the heaviest crusher loader and up to movable smelting furnace charging vibrating units. Our standard series conveyors can be seen on this and the adjacent page along with tables of dimensions.

We supply electro-magnetically driven small vibrating feeders for fine metering tasks to fill and meter small parts during: • the weighing and packaging pracess • orientation sorter for mass production metal parts • isolation of individual parts • counting and weighing of small parts of different shapes and sizes. Amount of vibration and conveying speed can in these cases be continuously varied (infinetively adjustable) by remote con­trol or by integration into measurement and contral circuits.

Vibrating hopper feeder We supply special interim storage electro­magnetic vibratory conveyors with high sided troughs to increase the supply capacity (hopper feeders) .

These feeders meter their contents to feed subsequent machines with predefined amounts .

They serve as interim storage of small mass produced parts and thus contribute to pro­duction process automation.

The inner surface of the trough is generally lined with an oil and grease resistant vul­canised rubber coating (to combat noise and abrasion).

These vibrating hopper feeders are controlled by fililevel sensors which measure the remain ing amounts at the subsequent machines and automatically top these up (usually with a time delay).

Hopper feeders can be used to replenish by weight control , e.g. for feeding hardening furnaces. Electric weight measurement cells conti­nuously check the weight remaining in the hopper feeder trough and thus control the weight of material to be suppl ied (weight metering).

The storage capacity of the various sized feeders lies between 3 to 250 gallons - 0,5 to 30 cb ft - 1 0 to 1 000 I.

Lifting and tipping device with subsequent vibrating hopper feeder

Vibrating hopper feeder

Our vibrating hopper feeders accept the hopper load to relieve the subsequent steep inclined conveyors and linkage units of the feeding load. Level feeders, which also fulfil an orientation sorting function, are sensitive to overload because the mass produced parts do not have sufficient space in the flights or within the belt space volume between the flights and are subject to pressure or jamming.

Vibrating hopper feeders are often installed after lifting and dumping units because such units only feed crude amounts of materials. Thus the lifting and dumping units can discharge only with crude amounts while the vibrating hopper feeders take over the task of feeding at a constant rate.

Filling and weighing devices in particular are served by such installations. Such combinations also find a variety of uses in galvanising, finishing and processing plants.
