Lime Digestion Process
Raw Material Preparation
After sieving, calcium oxide (quicklime block) is crushed and lifted to the raw material warehouse (lime storage warehouse) for standby.
Controlled Feeding
When digestion begins, calcium oxide (20~40mm block material) is quantitatively and uniformly fed into the lime digestion box through a vibrating feeder with adjustable speed.
Hydration Reaction
Natural water (H₂O) is added, and the calcium oxide absorbs water for 5~8 seconds, undergoing a chemical reaction that converts it to calcium hydroxide (Ca(OH)₂), producing large amounts of hot steam.
Steam Management
The hot steam, carrying some calcium hydroxide powder, is discharged through pipelines under fan action.
Dust Filtration
Spray nozzles create a water curtain wall that filters dust from the hot steam before it’s discharged into the atmosphere.
