Continuous Powder/Liquid Mixing – Challenges & Best Practices
Silverson Machines has recently added a new animation on continuous powder/liquid mixing to their Silverson Mixing Science series. One of the most challenging mixing tasks is continuous powder addition and dispersion into liquid, which requires precise control to achieve uniform results.
Challenges of Continuous Powder/Liquid Mixing
In order to be able to disperse powders into liquid efficiently, both powder and liquid must be accurately metered into the powder/liquid mixer. There are, however, several important issues to be resolved:
- Poor liquid flow rate – When the flow of liquid is inadequate, the mixer will be unable to accept the powder at the desired rate.
- Powder percentage limits – There is an upper limit to the powder that can be added in one pass.
- Air entrainment – Additions too small may allow air to enter the mix.
- Bridging in the powder hopper – When powder momentarily bridges in the hopper, liquid will pass through the mixer without powder being added.
Due to these issues, continuous feeding powder into liquid in a single pass is often not a viable option for most applications.
Recommended Solution: Batch/Recirculation Mixing
A batch/recirculation system typically eliminates these issues and offers a homogeneous, uniform product. The Silverson Flashmix is a typical powder/liquid mixer based on this concept.
Why Use the Silverson Flashmix?
In contrast to other powder/liquid mixers based on vacuum suction to pull powders in, the Flashmix uses a force-fed system forcing powder into liquid flow. Such unique approach achieves the following advantages:
✅ Effective dispersion and hydration of high powder levels
✅ Suitable for operation under high temperatures and with more viscous mixes
✅ Guarantees controlled and consistent incorporation of powder
Exploring Continuous Dispersion Alternatives
Though batch/recirculation mixing is often the preferred option, Silverson's new animation explores alternative means of continuous powder/liquid dispersion that can advantage industries to find the best means for their specific process needs.
With over 75 years' expertise in powder/liquid mixing, Silverson Machines can help you to find the most suitable solution for your application.
