Gypsum Powder Production Line

This gypsum powder production line is not just a mill; it’s a fully coordinated plant. It includes a jaw crusher to reduce large gypsum boulders (≤300 mm) to mill-ready size, a bucket elevator and silo for buffer storage, the core gypsum raymond mill with an integrated hot air furnace for drying and grinding, a high-efficiency classifier, a cyclone collector and pulse bag filter for environmental compliance, and an automatic packing machine. For plaster production, a directly connected gypsum calcination kettle or rotary kiln can be seamlessly added. You receive a single-source, ready-to-run gypsum powder manufacturing plant.

Raw gypsum often contains 5–15% free moisture that can clog a conventional mill. The core gypsum grinding mill in this production line is equipped with a hot air generator. As heated air sweeps through the grinding chamber, it flash-dries the moist gypsum while the rollers grind it into fine powder. No separate rotary dryer is needed, saving significant equipment investment, plant footprint, and thermal energy costs. Your gypsum powder making machine stays online and productive.

When producing cement retarder or pre-calcination powder, overheating will destroy the chemically bound water in dihydrate gypsum. Our gypsum raymond mill uses a high-volume air-swept design that keeps the grinding zone temperature well below the dehydration threshold. This ensures the output powder retains its full dihydrate crystal structure and physical properties, whether it is destined for cement mills or for subsequent high-quality calcination.

This gypsum powder production line can be configured exactly for your end product. For cement retarder or agricultural gypsum, the line stops at the grinding and packing stage, producing fine dihydrate powder. For high-value building plaster (β-hemihydrate), we integrate a continuous gypsum calciner immediately after the grinding and classification unit. This single gypsum powder manufacturing plant can be tailored to serve both markets.

The entire line is designed for efficiency. The gypsum grinding mill processes soft gypsum (Mohs 2) at up to 30 tons per hour depending on the model. Optimized airflow and a high-efficiency cyclone minimize energy losses, while the optional waste heat recovery from the calcination step can be reused for pre-drying, further reducing the fuel consumption of the whole plant.

The entire gypsum powder manufacturing plant is sealed and operates under negative pressure. Dust emission is controlled below 30 mg/m³. Centralized PLC control allows one operator to monitor and adjust the complete production process from the crusher to the packing machine. This reduces labor costs and ensures a consistently high-quality gypsum powder output.

A gypsum grinding mill is a single machine. Our gypsum powder production line is a complete plant that includes crushing, feeding, drying & grinding, classifying, dust collection, calcination (if needed), and packing. It’s a turnkey solution for mass production.

Yes. The line is modular. Without the calcination unit, it produces raw gypsum powder for cement. When the calcination kettle or rotary kiln is activated, the same upstream gypsum raymond mill system feeds the calciner to produce building plaster.

It efficiently processes natural gypsum rock, as well as synthetic FGD gypsum and phosphogypsum. Wet synthetic gypsum benefits significantly from our integrated hot air drying system in the gypsum powder manufacturing plant.

After the civil foundation is ready, installation and commissioning typically take 30–45 days for a complete line including calcination. Our engineers supervise the entire process to get your gypsum powder making machine plant operational fast.
