Many screening problems are caused not by the machine itself, but by incorrect assumptions during selection or operation. This makes processes unnecessarily unstable and troubleshooting more expensive than needed.
Selecting a machine based only on capacity
Capacity is important, but a high nominal throughput says little without context. Product behavior, required separation sharpness and mesh selection all influence what is achievable.
Selecting only on tonnage often leads to a machine that is large enough on paper but does not achieve the required product quality in practice.
Too little attention to product variation
A test with an ideal sample does not say everything if the daily product contains more moisture, more agglomerates or a wider particle size distribution. That variation determines how robust the solution really is.
Always include worst-case conditions when evaluating the process.
Thinking too late about maintenance and cleaning
A machine that screens well but is difficult to clean will eventually cause significant production losses. This is especially relevant in food, pharma and processes with frequent product changeovers.
Maintenance and cleanability should be included from the design phase. That prevents downtime and increases machine availability.
- Check access to screen decks and seals.
- Look at how quickly meshes can be replaced.
- Assess how easily product residues leave the frame.
No structured evaluation of results
Many companies only notice late that oversize, product loss or unnecessary wear is occurring. Without measurements of fraction quality, downtime and product loss, improvement remains reactive.
A simple evaluation of capacity, product quality and maintenance data makes it possible to optimize the screening process step by step.
