 This in-depth exploration is tailored to equip process engineers and sales personnel with not just a foundational understanding, but a profound appreciation for the critical roles these systems play. By grasping the interplay between these bins and their impact on productivity, professionals in these roles can not only advocate for their integration but also illuminate their value to stakeholders and clients, ushering in a new era of operational excellence

Live-Bottom Bins: Precision in Material Discharge

A Live-bottom bin is a type of storage container commonly used in industries where controlled flow and discharge of materials are crucial. What sets it apart is its dynamic bottom, often equipped with a form of belt conveyors or rotating elements, called picker reeds. These features help to meter and discharge materials in a controlled and uniform manner, akin to the controlled release of sand from an hourglass. Live-bottom bins find applications in a variety of industries, including agriculture, food processing, and bulk material handling.

Key Characteristics

Precise Material Flow

The dynamic bottom of a live-bottom bin allows for a controlled and even discharge of materials. This ensures that materials are released at a consistent rate, which is crucial in industries where uninterrupted an eve material flow are vital for the final product’s quality.

Prevention of Bridging and Rat-holing

One of the key challenges in material handling is the tendency of certain materials to ‘bridge’ or form a blockage within a bin. Bridging happens when the flow of material has come to a complete standstill because a permanent ‘arch’ or ‘bridge’ of material particles has formed. Traditional ways to break this arch consist of manual hammering, (pneumatic) knocking, shaking or applying vibration. However, these methods often cause the blocked material to compact further and firm up the bridge, making discharge by gravity impossible. The dynamic movement of a live-bottom bin’s bottom, coupled with negatively slopped bin walls,  disrupts these formations, ensuring a continuous flow without any interruptions or potential obstructions.

Customization for Different Materials

Live-bottom bins are incredibly versatile. They’re designed to handle a wide spectrum of materials, from fine powders to coarse granules to pelletized pieces. This adaptability makes them a go-to choice in industries dealing with a diverse range of materials.

Reduced Risk of Segregation

 In some materials, such as fine powders or particles with varying sizes, segregation can occur during storage or discharge. The controlled flow in a live-bottom bin minimizes the risk of these materials separating, ensuring a more consistent mixture.

Customizable Design

Live-bottom bins can be tailored to specific requirements. Our engineers at MPD have the flexibility to design the bin’s dimensions, angles, and picker configurations to suit the unique characteristics of the material being handled. Our engineers will create the best solution so as to seamlessly integrate with other material handling equipment within the facility, such as conveyors, processors, and packaging machinery. This ensures a smooth and continuous flow of materials throughout the production process.

Improved Safety and Reduced Energy Consumption

The controlled discharge of materials in a live-bottom bin reduces the risk of accidents or incidents that can occur with sudden, uncontrolled material flow. They also often require less power to operate compared to other types of material handling equipment. This can result in energy savings over time.

Surge Storage Bins: The Backbone of Production Continuity

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.

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.


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.
