Silo design is a crucial aspect in material handling and storage that, requires careful consideration of several key factors that might impact the performance. A well-designed silo not just stores and discharge materials in a consistent and reliable manner, but also minimizes issues such as bridging and rat-holing.
Have you ever wondered about the different types of flow patterns that can occur in a silo or the potential issues that can arise with silo discharge systems? In this article, we will explore these topics together, as well as discuss the essential factors to consider while designing a silo. This blog will provide you with a strong foundation of knowledge that you can use to deepen your understanding of silos in future blogs.
A mass flow silo for bulk solids is designed to ensure a first-in, first-out (FIFO) flow pattern. In this type of silo, moves uniformly. As the material is discharged from the silo, the material at the top of the silo moves downward to replace the material that has been removed, ensuring a constant flow pattern, and preventing the formation of stagnant zones.
In funnel flow silos, the flow channel discharges material in the middle first. As the silo empties, material from sides flows into middle and gets discharged.
To ensure good discharge, each silo is normally equipped with live bottom arrangements like bin activators, fluidising cones, unloading valves etc. This units ensure consistent and controlled discharge of various materials thus ensuring efficient inventory management and control, benefitting the plant operation and its flexibility, as well as the material supply chain management.
Founded in 1975, Rieco Industries Ltd is a leading manufacturer and supplier of silo discharge equipment and systems for various industries, including chemical, pharmaceutical, food, and mineral processing.
In conclusion, silos play a crucial role in many industries, providing efficient storage and handling solutions for bulk materials. The design also involves determining the appropriate flow pattern and selecting the best discharge system to ensure optimal performance and avoid common issues such as bridging and rat-holing.
