There are two types of slag gypsum: desulfurization gypsum, which is produced during the desulfurization process in thermal power plants, and phosphogypsum, which is produced after phosphorus fertilizer is extracted from phosphate ores. Most slag gypsum powders are superior in strength and hardness to natural gypsum powders. However, due to the presence of crystalline particles, slag gypsum cannot be completely pulverized during the grinding process. Compared to natural gypsum, slag gypsum has a completely different fluidity. This difference has a great impact on the dry mortar mixer, the mixing equipment and screw conveyor of the dry mortar production line, and the conveying unit of the fully automated dispensing system.
Given the impact of gypsum mortar on dry mortar mixing plants and dry mortar production lines, the impact is negligible if the customer purchases large or heavy dry mortar production line equipment. However, for most plants producing special construction mortar and dry mortar, the power and design standards of the equipment belong to the light equipment, and the impact is larger at this time. The fluidity of the product can be improved by replacing the equipment or adding a certain percentage of heavy calcium to the gypsum mortar (formula using slag gypsum powder). The use of slag gypsum production of gypsum mortar substrate also on the dry mortar mixer, bucket elevator, screw conveyor, and automatic metering and packaging machines have an impact on the bucket elevator and automatic metering and packaging machine selection of the same need to pay attention to this issue.
