We provide a turnkey Gypsum Powder Production Line designed to efficiently convert natural gypsum rock or industrial by-product gypsum (such as desulfurized gypsum and phosphogypsum) into high-value-added building gypsum powder, medical gypsum powder, and mold gypsum powder.
1.Gypsum Powder Production Line
Gypsum grinding plant, Gypsum powder manufacturing process, Raymond Mill Gypsum Powder Production Line is a complete set of equipment designed to process natural gypsum (CaSO₄·2H₂O, Dihydrate gypsum) or industrial by-product gypsum (such as FGD gypsum, phosphogypsum) into construction gypsum powder (β-hemihydrate gypsum). Using the Raymond mill (also known as the high pressure roller mill) as the core grinding equipment, gypsum powder production line integrates grinding, classifying, and calcining processes. It is widely used in building materials, chemical engineering, ceramics, medical, and food molding industries.
2.Core Equipment – Raymond Mill
The Raymond mill is the core of gypsum powder production line, offering several advantages:
Compact Structure: It integrates crushing, grinding, classifying, and conveying into one system.
Stable Operation: It features a three-dimensional structure, a small footprint, high system integration, and low energy consumption.
High Fineness: The finished powder fineness is adjustable between 80 and 325 mesh, meeting the requirements of construction gypsum.
Environmentally Friendly: The system operates under negative pressure to prevent dust leakage. Equipped with pulse dust collectors, it complies with stringent environmental protection standards.
3.Applications
The gypsum powder produced by this line is mainly used for:
Building Materials: Plasterboard (drywall), gypsum blocks, plastering gypsum, putty powder.
Molds: Ceramic molds, precision casting molds.
Others: Medical plaster (orthopedic casts), food additives (tofu coagulant), cement retarder.
The final gypsum powder fineness can be flexibly adjusted between 80-400 mesh (approximately 0.18-0.038 mm). Its sieving rate reaches up to 99%, effectively preventing the mixing of overly coarse or fine particles and ensuring stable final product quality.
Compared with traditional equipment such as ball mills, the Raymond mill can save more than 60% energy. Moreover, its key grinding components (grinding rollers and rings) are made of high-performance wear-resistant materials, offering long service life and low maintenance costs.
The production line adopts a fully enclosed negative pressure circulation system, effectively preventing dust leakage. Equipped with an efficient pulse dust collector, it significantly reduces dust and noise pollution during production, meeting environmental protection requirements.
The electrical system adopts centralized control, enabling unattended operation or operation with only a few patrol personnel, greatly saving labor costs.
1. Coarse crushing stage
Large pieces of gypsum ore (or waste gypsum) are first crushed to about 30 mm or less by a jaw crusher.
2. Conveying and feeding
The crushed material is sent into the storage bin by a bucket elevator, and then evenly and quantitatively fed into the Raymond mill main unit by an electromagnetic vibrating feeder.
3. Main grinding stage
The material is crushed by grinding between the grinding rollers and grinding ring in the Raymond mill main unit.
4. Classification and screening
The ground powder is blown by airflow into the classifier for separation. Qualified fine powder passes through, while unqualified coarse powder falls back into the main unit for regrinding.
5. Collection and finished product
The qualified fine powder enters the cyclone collector (or pulse dust collector) with the airflow to be separated and collected, finally obtaining finished gypsum powder, which can be packaged and stored.
