A Dome valve, also known as a segmented ball valve, offers a unique means to shut off and isolate a material flow for a dry bulk solid. The dome rotates approximately 90° out of the flow to allow for an unrestricted flow through the inlet orifice of the gate. When the material needs to be throttled or metered, the dome can rotate partially ...

The flow behaviour of the bulk material in these applications can range from quasi-static, e.g. bulk material resting on belt conveyor, to rapid flow scenarios, e.g. the bulk material stream in a transfer chute. Hereby, the rapid flow case is the predominant flow regime in …

Bulk material flow issues come with additional challenges in light duty applications where plastic hopper bins and intermediate bulk containers (IBC Tote) are utilized. Traditional methods of installing hopper vibrators to promote material flow, welding and bolting, are …

By measuring the flow properties of a bulk solid, the flow behavior of the material can be predicted, and more reliable hoppers and bins can then be designed. Competing flow patterns. Two primary flow patterns can occur in a bin or a silo: mass flow and funnel flow (Figure 1). In mass flow, the entire bed of solids is in motion when material is ...

For storage and handling of semi-free flowing dry, bulk materials; the 60-degree slope of the NBE mobile storage hopper cone helps prevent material bridging or ratholing. The steep cone slope naturally directs material to the hopper bottom for discharge through a slide gate, or by vacuum wand.

Why Flow Properties Testing? A thorough understanding of a bulk material's flow properties and its flowability are crucial for identifying the cause of poor flow, powder flooding or rate limitations, segregation, or product non-uniformity.. Flow properties tests are also critical when designing a new silo/bin/hopper, stockpile, feeder, chute, conveyor or other material handling equipment.

Best Practices: Utilize vibration and/or air cannons to dislodge material blockages. Manage, monitor, and maintain bins. Proper design of chutes to encourage evacuation of all material. Line the hopper to prevent material sticking. Proper selection of flow aid to match material/buildup.

Bulk density affects capacity and flow because of material-per-unit volume. Heavier materials tend to flow faster due to a higher momentum. Shear properties. Materials that are soft and spongy tend not to flow well from hoppers. Such types of material particles tend to pack into each other, causing bridging and promoting poor flow to the feeder.
