Storage Hopper with Live Bottom Arrangement ...

Storage bins are designed with minimum sidewall angles to ensure proper flow of residuals. A multiple screw feeder, known as a live bottom, is located on the bottom of the bin and meters residuals to trucks or dumpsters. The live bottom can utilize multiple discharge points with slide gates to aid in distributing solids in the truck or dumpster.

Silo Failures: Case Histories and Lessons Learned 1

• Be particularly careful with silos that have an elongated hopper outlet. An improperly designed screw feeder or belt feeder interface, or a partially opened slide gate, will often result in an eccentric flow pattern with accompanying non-uniform loads. • If a sweep arm unloader is used, be aware that operating it like a windshield wiper

Hopper Design Principles

 · Two types of flow patterns can occur when a bulk solid is discharged from a hopper, bin or silo: A typical funnel flow pattern is shown on the left, and a mass flow pattern is shown on the right By contrast, in funnel flow, an active flow channel forms above the outlet, but stagnant material remains (called ratholes) at the periphery of the vessel.

Construction and Maintenance of Belt Conveyors for Coal ...

During belt conveying, the material is lying on moving belt. Since the belt sags down between two idlers and rises up when passing on an idler, material particles on the belt is made to move up and down along the belt as it travels forward. This creates presence of vertically fluctuating inertial forces in the body of the bulk material.

How to Design Efficient and Reliable Feeders for Bulk Solids

Screw feeders are well suited for use with bins having elongated outlets. These feeders have an advantage over belts in that there is no return element to spill solids. Since a screw is totally enclosed, it is excellent for use with fine, dusty materials. In addition, its fewer moving parts mean that it requires less maintenance than a belt feeder.

Vibrating Feeder Design

Vibratory feeders are basically applied to a control function to meter or control the flow of material from a hopper, bin, or stockpile, much the same as an orifice or valve control flow in a hydraulic system. In a similar sense, feeders can be utilized as fixed rate, such as an orifice, or adjustable rate, as a valve.
