Gypsum Grinding

Gypsum Grinding

Gypsum grinding is an important process in cement, plaster, wallboard, and industrial mineral applications. The particle size distribution of gypsum influences setting behaviour, dissolution rate, product consistency, and downstream processing performance.

Maintaining consistent gypsum fineness can be challenging due to variations in feed moisture, purity, crystal structure, and grindability. These factors can affect mill stability, product quality, and process efficiency.

Traditional gypsum fineness control is usually based on manual sampling and laboratory measurement. This creates delays between process changes and corrective action, which can lead to inconsistent product quality.

Xoptix provides continuous online PSD measurement directly from the gypsum grinding process. Operators can monitor fineness in real time and respond quickly to changes in mill performance.

For cement applications, gypsum fineness can influence how effectively sulphate is available during cement hydration. Poor control may contribute to variability in setting time and final cement behaviour.

Overgrinding is also an important consideration. Producing gypsum finer than necessary increases energy consumption, reduces mill capacity, and may create handling or flowability issues.

By using real-time PSD data, producers can operate closer to the required specification while avoiding unnecessary safety margins. This improves efficiency and supports more stable product quality.

Xoptix helps gypsum producers and cement plants reduce manual testing, improve process visibility, lower grinding energy, increase throughput, and maintain tighter control of product performance.
