If you’re looking for optimal performance in the particle size analysis process, then real-time or ‘on-line’ particle size analysis methods, such as laser diffraction, are the way to go. There are several applications for real-time particle size analysis, including sticky-wet concentrated slurries, liquid emulsions, and dry particulate streams. With the use of automated on-line analysis, the frequency of measurement increases significantly, enabling a reliable and efficient data stream to be delivered.

Benefits of real-time particle size analysis

There are several benefits that can occur as a result of utilising real-time particle size analysers, outline below.

1. Increased return of investment (ROI)

These online instruments have been shown to be extremely sturdy and capable of providing 24/7 operation with only a small amount of upkeep. You can achieve visible ROI within six to 12 months of operation, with both product quality and plant capacity enhanced by automatic real-time measurement.

2. Lower energy

While milling operations are generally quite energy-intensive, consumption has been shown to see an exponential increase as particle size becomes smaller. Quality control failure can occur as a result of under-milling, while over-grinding can result in too much energy being used. With real-time particle size analysis you will see minimal energy use to create products that meet specifications.

3. Real-time control

From metal powders to pharmaceuticals, particle size is a key performance parameter in a lot of particulate products. Real time particle size analysis, therefore, makes a lot of sense. The on-line systems are capable of measuring up to four particle size distributions per second.

4. Troubleshooting

By utilising continuous measurement, you’ll be able to see the outcome of every variable in real time, which makes troubleshooting a lot easier than viewing these variables with the disadvantage of occasional off-line analysis methods.

5. Increased efficiency

Using off-line analysis to examine process parameters and their effects can be time consuming. With real-time particle size analysis, you’ll be able to evaluate these situations in minutes instead of hours. Causal links become clear at a much quicker rate than normal.

6. More intelligent process development

Since the acquisition of knowledge is the main role of process development, real-time measurement has obvious advantages. Potential problems can be detected at an early stage, speeding up the knowledge gathering process.

7. Quicker product changeover

Since, during changeover, you’ll want to get to the set point as fast as the plant dynamics will allow, on-line systems are definitely the way forward. Waiting on lab results to ascertain whether or not it’s safe to switch to the in-spec collection silo is no longer necessary; instead, you’re fed this information in real time.

8. Immediate upset detection

In general, offline analysis is done on an hourly basis (at most). As a result, any upsets may not be detected for an hour at best and response to upsets may take even longer – enough time to spoil a batch. On-line analysis allows upsets to be detected immediately.

9. Higher sensitivity to quality

Real-time data is sensitive to changing conditions, allowing for tighter process control. Off-line data, on the other hand, is usually an average taken from composite samples, which lacks the sensitivity necessary to spot out-of-spec samples.

10. Reduced operator risk

Occupational health and safety problems can arise during the sample extraction process, especially when materials are highly toxic or volatile. The use of a real-time particle size analyser eliminates this risk.
