gypsum powder production line

The gypsum powder production line is a full-automatic integrated industrial production system designed for processing natural gypsum, desulfurized gypsum and phosphogypsum raw materials. It completes a full set of processing procedures including raw material crushing, screening, fine grinding, high-temperature calcination, powder classification, dust removal and automatic packaging. Adopting advanced rotary kiln or boiling furnace calcination technology and closed-loop grinding system, this production line can stably produce high-purity building gypsum powder and industrial gypsum powder. With standardized modular design, intelligent parameter control and environmentally friendly production mode, it is a mature and reliable turnkey production solution widely used in building materials, chemical industry and industrial processing fields, realizing continuous, efficient and low-consumption mass production of gypsum powder.

• High Automation & Labor Saving: Equipped with intelligent PLC centralized control system, the whole production process from feeding, processing to finished product packaging runs automatically. It effectively reduces manual intervention, lowers labor costs, and ensures stable and consistent production procedures without manual operation errors.
• Stable Product Quality & High Purity: Adopts multi-stage impurity removal and precise powder classification technology. The produced gypsum powder features uniform particle size, stable fineness and high purity, fully complying with international building material standards and industrial application requirements, supporting diversified high-end usage scenarios.
• Energy Saving & Environmental Protection: Optimized calcination and heat circulation system improves thermal energy utilization rate and reduces unit energy consumption. The fully closed dust removal and circulation air duct system effectively controls dust emission, meeting global environmental protection emission standards and realizing clean production.
• Wide Raw Material Adaptability: Compatible with multiple gypsum raw materials including natural gypsum ore, power plant desulfurized gypsum and industrial phosphogypsum. It realizes resource recycling of industrial waste residues with strong raw material adaptability and high resource utilization rate.
• Customizable & High Efficiency: Supports customized configuration of production capacity and equipment models according to customer demands. The continuous assembly line production mode greatly improves output efficiency, with flexible production capacity matching small, medium and large-scale production projects.
• Low Operation Cost & Long Service Life: Core equipment is made of wear-resistant and high-temperature resistant materials, with stable performance and long service life. The optimized structural design reduces equipment failure rate and daily maintenance costs, ensuring long-term stable operation.

• Raw materials must meet the standard requirements: the dry-based calcium sulfate dihydrate content ≥90%, raw material moisture ≤15%, and impurity content shall not exceed the standard to avoid affecting finished product quality and equipment operation.
• Before starting the equipment, check all parts such as crushing, grinding, calcination and dust removal systems to ensure no abnormal noise, blockage or loose parts, and confirm the normal operation of the electrical control system.
• Strictly control the calcination temperature and feeding speed according to production requirements. Excessively high or low temperature will cause unqualified gypsum powder activity and fineness.
• The production workshop must be kept ventilated and clean. Regularly clean the dust removal equipment and circulating air duct to prevent dust accumulation from affecting production efficiency and environmental protection effect.
• Operators must receive professional training and wear protective equipment. It is forbidden to open the equipment cover or touch operating parts during equipment operation to avoid safety accidents.
• Regularly lubricate and maintain core equipment such as crusher, mill and rotary kiln, replace worn parts in time, and record maintenance data to ensure long-term stable operation of the production line.
• Stop feeding first when shutting down the equipment, and shut down the main equipment after all materials in the production line are completely processed to avoid material blockage inside the equipment.

• Construction & Building Materials Industry: Produce building gypsum powder for gypsum board, gypsum block, wall plastering, self-leveling mortar, indoor decoration and wall thermal insulation materials.
• Industrial Manufacturing: Supply high-purity gypsum powder for ceramic mold making, industrial casting molds, art crafts molding and chemical raw material processing.
• Environmental Protection & Resource Recycling: Realize recycling utilization of desulfurized gypsum from power plants and industrial phosphogypsum, turning industrial waste residues into reusable building materials.
• Other Special Fields: Applicable to food processing auxiliary materials, medical mold materials, agricultural soil improvement and other fields by adjusting production process and powder purity.
