Surge bins and buffer stockpiles play a crucial role in both material handling and inventory management across industries. Their primary benefit is to act as a buffer or safeguard, ensuring smooth and reliable operations even when faced with disruptions, fluctuations, or uncertainties. For wet-mining processes, eg dredging or hydraulic mining, or where fine ores are slurried close to the mining face, a surge-bin is used to contain the plant feed and smooth out the variations in mining rates (AusIMM, n.d.). This article highlights the benefits of using surge bins or buffer stockpiles in mining.
According to (Kittok, 2023), A storage surge bin, often referred to simply as a surge bin, is a specialized type of storage vessel used in material handling processes across various industries. Its primary purpose is to act as a buffer or reservoir for materials, ensuring a steady and consistent supply to downstream processes, even in the face of fluctuations in material input or processing demands. The same article provides some benefits of using surge bins:
Buffering Against Fluctuations
One of the primary roles of a surge bin is to absorb any irregularities or fluctuations in the incoming material supply. For example, in industries where raw materials may arrive in batches or with varying flow rates, a surge bin ensures that downstream processes receive a consistent supply. By acting as a buffer, a surge bin helps to smooth out any peaks or troughs in material supply. This ensures that production can continue uninterrupted, even when there are variations in the availability of raw materials. Our first in first out capabilities ensures the product does not stagnant.
Optimizing Equipment Utilization
Surge bins enable downstream equipment, such as crushers, mills, or conveyors, to operate at a more constant and efficient rate. This can lead to improved overall system performance and reduced wear and tear on equipment. And in industries where just-in-time production is critical, surge bins play a crucial role in ensuring that downstream processes receive materials exactly when they are needed, without relying solely on real-time supply. By providing a buffer, surge bins can also help prevent overloading of downstream equipment. This reduces the risk of equipment failures or accidents due to sudden surges in material flow.
Customizability
Just like the live-bottom bins, surge bins can also be tailored to meet the specific requirements of different industries and processes. This includes considerations like capacity, discharge rate, and material handling characteristics. Surge bins find applications in a wide range of industries, from manufacturing to food processing and bulk material handling. Their versatility and adaptability make them indispensable in various material handling scenarios.
