Gypsum Powder Manufacturing Machine

Gypsum Powder Manufacturing Machine

The gypsum powder manufacturing machine from Hengshui Decheng Machinery & Equipment Co.,Ltd transforms raw gypsum into a fine, uniform powder suitable for multiple downstream applications, including board making, plasters, and cement additives.

Machine Configuration

• Crusher Section: Reduces large gypsum rocks or industrial by‑products into manageable fragments.

• Grinding Mill: Typically a vertical roller or ball mill, achieving target fineness (e.g., 200–400 mesh).

• Calcination Unit: Rotary kiln or flash dryer heats material to 150–180 °C to remove crystal water and produce hemihydrate gypsum.

• Cooling System: Indirect air cooling prevents rehydration and ensures powder flowability.

• Silo Storage: Aerated silos maintain powder quality until further processing or packaging.

• Packaging Station: Automated weighers and bag fillers deliver product in 25–50 kg bags or bulk containers.

Performance Highlights

1. Consistent Fineness
   Advanced classifiers and real‑time particle size monitoring ensure uniform powder that meets strict reactivity requirements.

2. Energy Recovery
   Heat from exhaust gases heats incoming air, reducing fuel or electricity usage.

3. Dust Control
   Bag filters and cyclones capture airborne particles, protecting both equipment and personnel.

Operational Steps

• Feeding: Crushed gypsum is metered into the mill.

• Grinding: Material is ground to specified mesh size; oversized particles are returned for regrinding.

• Calcining: Ground powder flows into the calciner, where precise residence time and temperature yield consistent hemihydrate content.

• Cooling and Conveying: Cooled powder is pneumatically conveyed to silos.

• Packaging: Powder is dispensed and sealed for shipment.

With robust design and process controls, this machine delivers high‑quality gypsum powder with minimal downtime and maintenance.
