Small parts conveyors are vibrating conveyors used for discharging, conveying,
feeding, dosing and distributing fine-grained bulk materials and large
quantities of relatively small parts. Elektromag has been manufacturing these
conveyors over the years and leads the field in India.
They are used in many branches of industry, for example in the chemical and
synthetic materials industries, food processing, sand, gravel and stone
quarries, for small parts assembly mechanisms, in the foodstuffs and luxury
food sectors, paper making industry, and in sugar refineries, oil refineries
and foundries.
The compact small parts conveyor drives are available in a range of sizes and
can be fitted with attachments such as troughs, tubes or rails.
The drive on small parts conveyors are available with a trough already mounted. They are standard items in our programme of products for distributing and dosing bulk materials. They can also be supplied with feed hoppers and hopper vibrators if required.
The power units allow the conveyors to be run off an AC mains amd the amplitude to be set at any level between almost zero and the rated value.
ADVANTAGES OF SMALL PARTS CONVEYORS
Small parts conveyors are two mass vibration systems tuned near to resonance.
The drive section contains the elements which induce vibration, that is an
electromagnet, base housing, trough carrier and springs.
The attachment is fixed to the drive unit so that it is easily removable. The
system is desinged to meet individual requriements and ensure a constant
level of vibration.
Each drive unit must be connected via the approprite power unit. With the
amplitude controller the feed rate can be varied over a very wide range.
Small parts conveyors are mounted on rubber mounts to ensure that virtually
no vibration is transmitted to surrounding areas.
The table on the reserve mentions standard sizes of small parts conveyors
fitted with a trough. Depending on individual requirements, the troughs can be
totally enclosed with spigoted inlets and fitted with screen sections etc.
On request, other attachments can be built in order to meet special
requirements for example, conveyors with multiple drive etc.
Rails for conveying oriented parts are always built on order, so as to suit
the dimensions of the items being conveyed.
Almost all standard troughs are manufactured from stainless steel and are
polished electrochemically. In some cases the trough are made up of synthetic
materials or light alloys. If trough lonings are required, a range of
different materials is available to meet the requirements of individual
installations.
If customers make their own conveying attachments (trough rail etc.) they
should ensure that it is suffciently strong to withstand the vibration. Long
lengths, low side-walls without increased mechanical stiffness, thin sheet
metal, or excessive widths without reinforcing struts should be avoided.
CONSTRUCTION AND OPERATION
APPLICATION
Individual components are available separately and are always compatible with
each other. For example, a small parts conveyor is made up of a small parts
conveyor drive and an attachment (trough or rail).
FEED HOPPERS
POWER UNITS
Three sizes of stainless feed hoppers are available to suit the range of
different small parts conveyors. The volume of the hopper and the diameter of
the discharge outlet are determined by the width of the standard trough used.
The feed hoppers are adjustable for height and are attached to a special frame.
The base-plate of the frame supports the small parts conveyors, thereby
forming a single unit (fig. 3). The vertical adjustments makes it easy to
regulate the layer height in the trough, which in turn controls the delivery
flow. If required, the feed hopper can be supplied with a viabrator which
causes the material being conveyed to discharge more easily.
Small parts conveyors are always connected to and driven by power units
running of 50 Hz AC mains. These connection units are available separately.
They make it possible to alter the amplitude, thus varying the delivery flow
almost 0 to 100%. On the enclosed version (fig. 4) the on/off switch and
amplitude adjuster are mounted on the front panel. The control cpmponents can
also be supplied separately for building into composite control systems.
