Ion exchange resin drying is a vital post-regeneration or pre-storage process in water treatment, chemical purification, hydrometallurgy, and pharmaceutical industries. It involves removing excess water from the porous polymer beads after their chemical activation cycle to ensure stability, prevent microbial growth, and facilitate handling or transportation.
Key Challenges
Structural Integrity: Aggressive drying can fracture beads, reducing surface area and efficiency.
Functional Group Sensitivity: High heat (>80°C) degrades quaternary ammonium (anion resins) or sulfonic groups (cation resins).
Moisture Gradient Risk: Uneven drying causes internal stress → bead rupture.
Static Electricity: Dry resins generate dust and static, posing explosion risks (organic matrices).
Common drying machine:
Vibration Fluid Bed Dryer
The vibration source is driven by a vibration motor, which has balanced operation, easy maintenance, low noise and long service life.
High effection, raw material is heates evenly and heated evenly and heat exchange is fully used and dry capacity is high. Compared with ordinary drier, the energy can be saved about 30%.
