Dry Minerals Grinding

Dry Minerals Grinding

Dry minerals grinding covers a wide range of industrial minerals, including limestone, dolomite, feldspar, quartz, talc, barytes, kaolin, and other mineral products. Across these applications, particle size distribution is a key quality parameter that affects product performance and customer acceptance.

Different minerals have very different grinding characteristics. Hardness, abrasiveness, moisture, feed size, and mineral composition can all influence mill stability and product fineness.

Traditional dry mineral quality control is often based on manual sampling and laboratory particle size measurement. This approach provides useful information but creates delays and limits operator visibility between samples.

Xoptix provides continuous online PSD measurement directly from the grinding or classification process. This allows operators to monitor product fineness in real time and take corrective action immediately.

Dry mineral producers often manufacture multiple grades for different markets. Maintaining consistent PSD during normal production and product changeovers is essential for reducing waste and meeting customer requirements.

Real-time PSD monitoring helps reduce the need for conservative operating margins. Mills can be operated closer to the required specification without increasing the risk of producing off-specification material.

Xoptix measurements can support process optimisation by providing feedback for classifier speed, airflow, mill feed rate, grinding pressure, and other operating variables.

With continuous PSD visibility, dry mineral producers can improve product quality, reduce laboratory workload, lower energy consumption, increase throughput, minimise off-specification material, and achieve more stable process control.
