Flexible Spiral Conveyor
Flexible Screw Conveyor
technology is the leading conveyor technology for the widest range of
material particle, bulk densities and flow properties. Flexible Screw
Conveyors are often the lowest cost means of transferring dry bulk solids
from one point to another.
Dust-free in operation :
The Spiroflow flexible screw conveyor is completely sealed operation. Air
isn't used as a conveying medium, there's no risk of dust contamination or
humidity from the atmosphere. In addition, the presence of dust can cause
not only airborne contamination of other products, but can also pose a
threat to the working environment.
Gentle handling of product
The rotating flexible screw conveyor spiral, being centralised within the
conveying tube, gently moves the material without degrading it. Its unique
action also eliminates the risk of mixed product separation.
action of the Spiroflow flexible screw conveyor ensures the material is
being constantly remixed.
This is particularly important when feeding pre-mixed product to packaging
and tabletting machinery.
Design simplicity :
of operation is the key element in Spiroflow flexible screw conveyors. The
only moving part is the motor driven spiral which rotates within a sealed
tube to move the materials along with it. This eliminates the need for any
additional operating equipment such as filters or bearings -resulting in a
system that's low on installation costs and high on efficiency and
Easy to clean :
simplicity of the Spiroflow flexible screw conveyor system makes cleaning a
simple operation. The electric motor may be reversed to empty the conveyor
of residual material which can then be flushed out with water or cleaning
solution. If necessary, the spiral can be quickly removed from the tube, and
optional quick release connectors enable rapid dismantling and reassembly to
Low maintenance :
As the only moving part of a Spiroflow flexible screw conveyor is its
robust inner spiral, trouble-free operation is ensured
FLEXIBLE SCREW CONVEYORS
Some basic facts about Spiroflow flexible screw conveyors.
Spiroflow flexible screw conveyor spiral selection.
- Electric motor: 3 phase, 50/60hz, voltage as specified. Special
motors are also available to your specification. Fixed or variable
- Motor adaptor and spiral connector in mild steel or stainless steel.
- 45 degree or horizontal outlet assembly in mild steel/painted, or
- Dust-tight tube fitting.
- High and low level control.
- Abrasion resistant polymer outer tube.
- Flexible screw conveyor spiral in spring steel or stainless steel.
- Inlet assembly in mild steel/painted, or stainless steel.
- Feed restrictor to regulate material flow.
- Feed hopper in standard size or to customer's specifications.
ROUND SPIRAL flexible screw conveyor forces some of the solids outwards
between the spiral and the tube, which reduces friction and lowers the load
on the drive motor. Its gentle tumbling action disperses the product within
the tube, preventing separation of mixtures, actually aiding the mixing
process. Round spirals provide the best combination of conveying and mixing
efficiency, strength and long life.
FLAT SPIRAL flexible screw conveyor, manufactured from rectangular wire,
directs more positive forward force in the direction of flow and increases
capacity slightly. It is particularly suitable for light, aerated or very
fine materials which demand a greater surface area to assist their movement,
with less fallback. Typical applications would be for talcum powder, fire
extinguisher powder, filter aids (e.g. diatomaceous earth).
PRO SCREW bevelled profile flexible screw conveyor is designed for conveying
difficult materials like iron oxide, pigments and other caking, smearing or
cohesive products. Due to the close tolerance between the tube and spiral,
length and conveying capacity are limited. This profile is semirigid, so
bends are not permitted. However, steep conveying angles can be achieved.
CENTRE CORE is used for:
- Very light materials that fluidise readily.
- Conveyors inclined more than 60°.
- To prevent flooding/ overfeeding of certain solids in short or
: All spirals are heated treated to provide strength
and long life. For products with high bulk densities, a heavy duty spiral
may be specified, used in conjunction with a steel outer tube for abrasive
versatility across the widest range of industries.
Spiroflow flexible screw conveyors are installed worldwide in a multitude
of industries because of their versatility and ability to take a wide range
of particle sizes, bulk densities and flow properties in their stride.
Hygienic ingredients handling is the fundamental benefit of
Spiroflow equipment, designed to satisfy the stringent demands of the food
and allied industries.
Accuracy, hygiene and consistent feeding are prime
requirements in the pharmaceutical field.
Spiroflow solids handling equipment is widely
chosen to ensure efficient feeding of moulding, extrusion and mixing
machinery in the volume Manufacturing sectors.
Spiroflow's long experience within the chemicals
industry ensures the safe handling and accurate metering of these often
Water treatment :
Spiroflow supplies efficient dosing equipment for
hydrated lime, activated carbon and other chemicals used in water treatment.
No bulk handling tasks are more arduous than in
minerals and ceramics. Spiroflow equipment is robustly built to meet the
most exacting demands.
