New ‘Spirostore’ Flexible Silos

Posted on 3rd September 2008 by

We announce the addition of a new, economic range of flexible silos that provide tailor-made solutions for the quick, efficient and safe storing of bulk solids and ingredients for most industries.

Unlike steel or aluminum silos, our new ‘Spirostore’ Flexible Silos are made of a robust, durable and yet flexible polyester fabric supported on a steel frame. They can store up to 7,000 ft3 of dry bulk material of up to 90,000 lbs in weight.

‘Spirostore’ Flexible Silos are manufactured like a custom-made suit regarding shape, size and the type of polyester fabric selected. They are adapted to meet each customer’s specific requirements in terms of available space, product specifications and how the product is to be discharged. We believe that no other bulk solids storage system can match the flexibility of flexible silos.

These silos are suitable for almost any indoor or other weatherproof location and can be connected to any type of ‘Spiroflow’ Flexible Screw, Aero Mechanical, Pneumatic, and Vacuum Conveyor system to fill and/or empty the stored material.

‘Spirostore’ Flexible Silos are ideal for use in the plastics, waste recycling, chemical and pharmaceutical industry as well as sectors of the food, animal feed and the confectionary industries. The materials that can be stored are equally varied and range from trouble-free peas and polystyrene balls to interlocking materials such as baking flour, color pigments and clumping materials such as tea leaves, fiberglass and shredded wool.

“Our ‘Spirostore’ Flexible Silos allow customers to quickly and economically expand their storage capability for bulk solid materials in a way no other silo can,” confirms Michael Podevyn, our President and CEO. “That’s one of the main reasons why this type of silo is generating so much interest. They are cost effective when compared to a steel silo with similar capacity, they are lightweight and are very easy and fast to install. They are delivered ‘flat-pack’ making it possible to deliver them to their destination through regular doorways”.

Customizing a ‘Spirostore’ Flexible Silo involves determining how much space is available to erect the system, selecting the type of polyester fabric that meets the product requirements and selecting from a multitude of possible variations in the outlet area for safe and efficient discharge of the contents.

‘Spirostore’ Flexible Silos optimize the use of space due to its square or rectangular shape – versus the cylindrical shape common for many other types of silo. This allows easy placement of silos in tight fit areas and also allows assembly in locations normally deemed inaccessible. The silo also precisely adapts to the headroom available. The lightweight design of the silos also means that no complex foundations are required to support them.

The main component of ‘Spirostore’ Flexible Silos is the high strength, durable polyester fabric ‘vessel’ supported by a steel frame. A variety of fabric options are available to meet product requirements. These include a breathable fabric that prevents condensation, air-tight, coated and uncoated fabrics, fabrics for use in food applications, electrically conducting fabrics for safe discharge of electrostatic charges plus numerous others.

Also available are a multitude of variations for the outlet area including outlet diameter, cone angle and a choice of discharge aids. These are precisely adapted to fit the requirements of the stored material. The flexibility of the polyester walls provide excellent discharge characteristics in that they assure almost total discharge of the material and provide optimum flow out characteristics.

Discharge aids guarantee safe discharge of contents, are gentle to the stored material, are easily cleaned and maintained and use minimum power. Four different types of discharge aids are available: ‘SpiroSlip’, ‘SpiroAir’, ‘SpiroFlex’ and ‘SuperSpiroFlex’.

‘SpiroSlip’ ensures that outlet walls have the highest degree of smoothness; ‘SpiroAir’ re-introduces air into the bulk goods thus enhancing flow; ‘SpiroFlex’ flexes the cone section; and ‘SuperSpiroFlex’ with its large hoses constantly change the form and outlet angle of the silo cone.

‘Spirostore’ Flexible Silos are have high rigidity and load carrying capabilities with a 7:1 safety factor for seams and fabric. Their robust and durable construction ensures long life, safe operation and low operating and maintenance costs.
