Particle size measurement
The OPC is integrated directly into the grinding process of the hammer mill. Regrind is fed into the OPC via a bypass and the particle size is determined there using a camera. The measurement data is then evaluated in the OPC software, which is available in several languages. If the particle size deviates from the previously defined specification or if there is a screen break, the OPC software informs the operator.
This automated and integrated measuring process increases throughput because the grinding process does not have to be interrupted during the analysis. Due to the continuous analysis, the quality of the ground material is also improved.
Your Advantages
Effective monitoring of the grinding process
- Detection of screen breakages or damages in the mill
- Detection of wear on beaters and screens
- Output of two individually definable alarm values in the case of deviations from the target particle size distribution, e.g. if the proportion of coarse or fine particles is too high
- Real-time measurement for immediate reaction
Increase of the plant availability
- Optimisation of maintenance intervals due to particle size changes during operation
- Predictive maintenance of the mill possible
Suitable for many applications
- For free-flowing bulk materials of all kinds
- Purge air connection for cleaning, can also be used for greasy and sticky products
