Flexieble Spiral Typ SF
 
Dust-free transport in curves and ascending gradients with low noise development. Economical in energie expenditure, reliable and tailor-made to suit all requirements.
Flexible spirals are made of specially hardened steel and are characterised by their high tensile strength and elasticity. Through this it is possible to convey various media – horizontally, vertically or in curves – without an axle.
   
Through the smooth movement of the spirals and the absence of corners, gears or chains the installation is completely maintenance-free.
The conveying system can be supplied in various sizes – from a conveying capacity of 0.09 m³/hour to 20 m³/hour.
Fields of application are very extensive and range from filling of silos or containers, loading and unloading of lorries, charging machines, sack filling and waste disposal, as well as the replacement of many manual operations.

Pipes and pipe bends are made of special PVC with smooth inside surfaces, which are more wear resistant and durable than other PVC grades. For abrasive and aggressive media galvanised metal pipes are used, and for metal pipe bends hardened steel. If required we can construct the plant in stainless steel.
 
Driving station
The driving station is fitted with automatic transmission-controlled or frequency-controlled motors, according to requirements. Motors of 0.37 kW up to 4 kW are used, depending on the spiral type and medium and the required conveying capacity per hour.
This gives the maximum conveying capacity with a minimum of energy expenditure.
 
Receiving station
 
Receiving hoppers are available in various designs, each being adapted to the medium to be conveyed and the storage container.

Discharge Points

Any required number of discharge points can be fitted to the conveyer pipe. Discharge at any particular point is possible through the use of mechanical or automatic shut-off valves.
 

Control

Our individually programmable control systems can be specially adapted to your requirements. They enable the spiral conveyers to be converted into dosing and/or w eighing machines or mixing units.
 

Maintenance

Our conveyers are tailor-made for every application and are maintenance-free.
