• Fixed or mobile installations

The pneuCONVEYOR –  flexible screw conveyor can also be customized to conform to the specific mode of operation you need it to perform:

Spiral profiles :  For most applications, the standard round spiral is suitable, combining strength and flexibility. Flat section spirals are recommended for certain light or aerated products.

The pneuCONVEYOR bevelled profile is used for conveying difficult materials such as iron oxide. Semi-rigid construction enables steep conveying angles to be achieved without bends.

The centre core is used for for very light materials that fluidise readily and for conveyors inclined more than 60°. They are also used to prevent flooding / overfeeding of certain solids in short or horizontal conveyors.

All spirals are heat treated to provide strength and long life. Heavy duty spirals are also available for certain high density or aggressive materials.

Simple Design : Simplicity of operation is the key element in the pneuCONVEYOR – flexible conveying system. The electric motor driven spiral, which is the only moving part, rotates within a sealed tube, moving the materials along by its rotating & moving screw action.

This design simplicity eliminates the need for any additional operating equipment such as filters or bearings – all adding up to a system that’s hygienic, easy to clean, low on installation and maintenance costs and high on efficiency and performance.

Dust free : During the materials conveying process, even the most harmless ingredients can become a hazard when they appear as dust in the atmosphere. The pneuCONVEYOR conveying system is totally sealed during operation and, because air is not used as the conveying medium, there is no need for filtration nor is there a risk of dust contamination escaping in to the atmosphere – critical for applications involving active pharmaceuticals and hazardous chemicals.

Easy to clean : The simplicity of the pneuCONVEYOR conveying system makes cleaning a simple operation. Conveyors can be emptied of residual material by reversing the motor and then dry cleaned by brushing or, if necessary, flushed through with water or cleaning solution. Optional, interlocked, quick release connectors facilitate rapid dismantling and reassembly where dry cleaning of the spiral, tube and end connections is essential.

Gentle handling : The rotating spiral is centralised in the tube by the product and, as a result, there is little to no product degradation. Spiral type and speed are carefully chosen to ensure the product is conveyed in the optimum manner.

Constant remixing & feeding : The unique action of the flexible spiral conveyor eliminates the risk of product separation that can take place in conventional pneumatic conveying systems where mixed materials have components of differing densities and / or particle size. In fact, the pneuCONVEYOR system ensures constant remixing; restoring every part of the mix to its desired proportions many times a second. This is essential when feeding pre-mixed ingredients to packaging and tableting machines.

Low maintenance : As the only moving part of a pneuCONVEYOR-  conveyor is its robust inner spiral, trouble-free operation is ensured. Our spirals are specially heat-treated and tempered for maximum working life.

Easy installation, minimum disruption : The flexibility of pneuCONVEYOR  conveying systems is unlimited. They can be configured to convey in any direction and in any elevation between horizontal and vertical. They can be installed over, under and around existing plant and equipment. And they can easily be manoeuvred round obstacles and through small openings in walls to maximise valuable factory space. Multiple conveyors linked outlet to inlet enable conveying over longer distances. Multiple inlets and/or multiple outlets are possible on a single conveyor to create a distribution system such as transferring ingredients from storage to a line of processing or packaging machines.

Heavy duty conveyors : We offer a range of heavy duty conveyors with Ultra High Molecular Weight Polyethylene (UHMWPE) tubes for abrasive or high bulk density materials.

Mobile conveyors : For added versatility, mobile conveyors are available. Easy to move and simple to operate, they are ideal for the intermittent feeding of several process machines. Additionally, they are easy to remove from the process area for cleaning elsewhere

Jumbo Bag unloaders : pneuCONVEYOR provides a full range of equipment for the discharge of materials from Bulk Bags. Many different models are available to meet the majority of industrial applications, including discharging by weight or volume, and with a hoIst of optional features to satisfy individual requirements.

Silo / Bin emptiers : pneuCONVEYOR designs vibrating discharge frames for all kinds of rigid metal and plastic IBCs and Bins / Silos to ensure complete emptying of product into the integral flexible screw conveyor. Systems are fully sealed, dust-free and allow discharge of bins either by volume or by weight.

The  pneuCONVEYOR – flexible screw conveyor is engineered to meet all standard expectations plus provide the precision performance and custom flexibility to handle all of your powder handling needs. Our decades of experience—both with this type of conveyor and the challenges of handling powders—will ensure that we provide the correct options for your particular application.
