The Tietjen Online Particle Size Controller (OPC) measures the particle size of free-flowing bulk solids inline, providing continuous, user-defined control of the grist spectrum between 160 and 6000 µm. This approach ensures a consistent grist spectrum over time and across multiple batches or recipes. As a result, the quality of the grinding material is increased. Less raw material is lost, as deviations in the grinding quality are detected promptly and faulty batches are thus avoided or greatly reduced.
The continuous monitoring of the grist spectrum also allows for the current wear of screens and hammers to be indirectly monitored. Maintenance can be carried out at the optimum time depending on the condition, which reduces costs due to rejects and at the same time saves the budget for maintenance parts.
