STB can provide creative silo discharge solutions, bulk storage silos and innovate feed & conveying systems, for the storage and handling of food ingredients, plastic pellets, powders & polymers, fine chemicals and mineral storage.

Silo discharge systems we offer in this range include:

  • Silos, process vessels, hoppers and bins in carbon steel, stainless steel and aluminium
  • Discharge devices engineered to suit the product and applications
  • Feeding and conveying systems including screw conveyors, pneumatic conveyors, belt and bucket conveyors, rope and disc, air slide conveyors, vibratory conveyors and vibratory feeders

STB Engineering’s manufacturing division designs, fabricates, builds and installs all types of bulk storage silos. From tanker delivery to silo and corresponding downstream distribution, STB can offer a complete solution for bulk storage and discharge transfer. Silos manufactured in aluminium and stainless steel makes them easily cleanable, hygienic and long-lasting storage solutions.

Other benefits of STB bulk storage silos include the enabling of processing operations to reduce inventory costs, labour, and materials whilst increasing the lineup time throughout.

The design and geometry of a silo and its discharge system can affect the way products are discharged. The pattern of flow and type of discharge is dependent on many factors, but the two main types are:

  • Core Flow (also known as Funnel Flow)
  • Mass Flow

 Core Flow

Most silos, hoppers and bins give core flow due to the shallow cone and small outlet which is usually set by the materials flow and friction factor.

Mass Flow

With steeper cones and larger outlets, mass flow can be achieved. Careful design dependant on product characteristics and silo geometry can produce mass flow where the product moves and discharges from the silo en-masse.

We can accommodate silos up to 4.2m diameter and over 20m in length in our workshops/factory. We specialise in the production of food quality stainless steel/aluminium as well as painted mild steel construction. We offer FEA and the latest Solidworks & AutoCAD design as well steelwork and support structures for a complete storage silo installation.

Our design and building expertise combined with high quality of finish of our storage silos for sale has led to our customers coming back to us time and time again. Contact STB Engineering for more information, or to further discuss your needs.
