Description

Bulkmatic Bulk Storage Silos are designed to meet stringent safety requirements regarding structural integrity and stability. Non-destructive tests are performed during the manufacturing process to ensure that this integrity is not compromised. Every silo is supplied with a structural certificate signed off by a professional Engineer. Where necessary silos can be supplied with explosion vents, earthing straps and explosion prevention measures.

The silo outlet can be fitted with flow assisting devices such as aeration pads or vibrating bin dischargers. Standard filter flanges are fitted to the roof of the silo to tie in with commercially available reverse jet filters.

Provision can also be made for mounting loadcells in the support structure as well as fitting of tanker loading pipes and roof access via an attached catladder. Intermediate platforms are supplied to ensure that maximum permissible catladder height is adhered to.

Silos up to approx. 5m in diameter and 20m in length can be transported in one piece while silos with larger diameters and lengths are generally delivered in sections and then site erected. Lagging, trace heating and cooling facilities can be added to silos as optional extras. Materials of manufacture are mild steel and stainless steel. Support structures are designed to customer requirements.
