Flexible Silos

Flexible Silo Storage System

Flexible Silos are the most versatile and cost-effective solution for the storage of bulk powder and granules. Manufactured from trevira tissue, a tough non-toxic fabric, the silos can handle particle size down to 2 microns and can be pneumatically loaded without the need for a dust collector. The 45-degree fabric silo cone flexes freely when the product discharges, enabling the efficient flow of hard to handle products such as sugar, flour, calcium carbonate etc., minimally assisted by a small vibrator fitted to the discharge transition. The trevira tissue is able to breathe, preventing condensation from forming on its internal walls. This eliminates lumping and caking of the product.

With sizes ranging from 2m3 to 50m3 a flexible silo is available to suit must applications. The flexibility of the trevira tissue allows for easy maintenance and cleaning of the silos. Strengthened braces are stitched on the outside of the silos to increase the mechanical resistance of the tissue. The silo and support frame can be walked through a normal door and clipped together in minutes making it ideal for utilising in otherwise inaccessible locations.
