Wet ball mill: Grind the material into a slurry with a certain concentration (generally 6070%). ... In addition to grinding clinker and gypsum, ball mills can also be used for grinding other materials such as slag, pozzolan, dolomite, and fly ash. These materials are added to the cement to improve its properties, such as strength and durability.

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, drywall and blackboard or sidewalk chalk. Gypsum also crystallizes as translucent crystals of forms as an evaporite mineral and as a hydration product of anhydrite.

Step 1: Wetting The first step to wet grinding is eliminating air from the surface of the raw feed, so that each individual particle is fully in contact with the liquid slurry. Ensuring complete contact is vital for effective milling. This requires a liquid with lower surface tension than the free surface energy of the solid.

4. Grinding process. In the ball mill, the material is mainly crushed by impact and friction. In the vertical grinding mill, the material is mainly extrusion, and grinding is the auxiliary. The residence time of the material in the vertical mill is 23 minutes, while in the ball mill it takes 1520 minutes.

Wet ball mill. A wet ball mill is suitable for materials that will not change properties when contacting with water. Water flow (or absolute ethanol) participates in the wet grinding process, and the movement of materials is driven by water flow. In an AAC block plant, sand, fly ash, or gypsum can be ground by a wet ball mill.
