Fine powder flow phenomena in bins, hoppers and processing vessels

(Whitepaper)

Fine powders present problems that bulk solids do not when they are contained in a bin, hopper or processing vessel. The primary problem is the powder's flow pattern. This 10-page PDF whitepaper discusses solutions to this problem.

Optimize Humidity for Efficient Powder Handling

(Article)

Too much or too little moisture can cause problems during processing and storage

Powder Handling: Conduct Flowability Tests

(Article)

Plants often offer telltale signs of flow problems, such as a hammer or barrels near equipment or welded-on patches. Flowability testing is expensive and, so, frequently neglected during process development but can head off potential issues.

Process Puzzler: Be Level-Headed With Solids

(Article)

Measuring solids can be challenging when moisture is present.

Continuous Powder Processing Focuses On Tubular Blenders

(Article)

science-based methods for process scale-up must be developed.

Powder Handling: Bulk Bags Can Change Your Life

(Article)

A plant should assess several critical factors such as how material will be unloaded or loaded, how sensitive a material is to attrition, agglomeration, vibration and mechanical deformation, and what will be done with used bags.

Emerson Introduces Rosemount 5708 Series 3D Solids Scanners

(Product)

Emerson Process Management introduced the Rosemount 5708 Series of 3D Solids Scanners for the continuous measurement of level, volume and mass of bulk solids and powders in large vessels, bins and silos.

Powder Handling: Don’t Err About Fluidization

(Article)

Particle fluidization often can offer important benefits such as improved heat transfer and possibly better mixing. Even when attrition or product segregation poses risks, limitations can be designed around or even used to advantage. Here’re some tips.

Powder Handling: Talk to a Chemist

(Article)

Chemists developing a process don’t have the same concerns as engineers trying to scale it up. However, a chemist can identify the physical properties and extrinsic conditions that control various steps and ease coming up with a meaningful design.

Powder Handling: Beware of Blending Myths

(Article)

Blenders often don’t perform properly because users have accepted certain myths — e.g., ones related to blending time, equipment comparability and fluidization. This column debunks those myths and provides some pointers for successful blending.

Powder Handling: Develop Drying Curves

(Article)

When faced with a drying problem, use drying curves to take a closer look.

Get a handle on solids’ flow

(Article)

Properly accounting for how bulk solids actually will flow in a vessel or overall process can be crucial for successful operations. Learning some simple parameters can often provide a good sense of flowability.

Treat Particulate Solids Like An Eclipse

(Article)

Sometimes, engineers are surprised when well-known scientific principles explain the actions of particulate solids.

Solids Processing: Prevent Problems with Fine Particles

(Article)

Sampling is crucial and demands particular care because fine particles tend to not follow the path of other particles and are more susceptible to segregation. Two problems that arose — with a thief sampler and with a blender — provide important insights.

Avoid confusion with air injection for fine powders

(Article)

Fine powders often need air injection to increase flow rates to an acceptable level. With entrained or injected air, powders flow like water, but when deaerated, the extremely low flow rate may be confused with a hang-up or arching condition.

Solid Handling: Stop Struggling With Your Slurry

(Article)

everal approaches exist to help resolve the issue of solids settling in slurries.
