About High Frequency Screen

Soda ash (Sodium Carbonate), in both Light Soda Ash (LSA) and Dense Soda Ash (DSA) forms, demands tight particle size control to meet downstream process, packaging, and end-use specifications. Conventional rotary or low-frequency vibrating screens often struggle with blinding, segregation, and inconsistent cut sizes, especially at finer ranges.

High Frequency Screens (HFS) provide a proven solution for precise protection and classification screening of soda ash across critical size fractions.

High Frequency Screens are effectively used for multi-cut classification of soda ash at:

• 250 microns (fine dust removal / product polishing)
• 600 microns (intermediate classification)
• 1.0 mm (oversize protection / lump removal)

These cut points are critical for controlling flowability, bulk density, and consistency—especially for DSA applications.

Protection screening is essential before:

• Packing systems
• Pneumatic conveying
• Dense phase transport
• Silos and reactors

High Frequency Screen benefits in protection screening:

• Removes foreign particles, agglomerates, and oversize lumps
• Prevents choking of chutes and pipelines
• Protects bagging machines and downstream equipment
• Ensures uniform material feed

Typical protection cut sizes: 1 mm or 600 microns

High Frequency Screens excel in classification duty, where accurate separation of size fractions is required.

• Efficient removal of ultra-fines below 250 microns
• Reduced dust generation
• Improved handling and packing efficiency

• Precise separation at 600 microns and 1 mm
• Consistent bulk density
• Improved performance in glass, detergent, and chemical applications

• High G-force vibration ensures sharp separation
• Fine aperture stainless steel media (250 µm to 1 mm)
• No screen blinding, even with hygroscopic material
• Low residence time, minimal degradation of particles
• Compact footprint for retrofitting in existing plants
• Low power consumption compared to conventional systems

• Tighter size control → better product consistency
• Reduced recycle load
• Lower dust losses
• Improved plant efficiency and uptime
• Reliable operation for continuous soda ash production lines

• Final product classification of LSA & DSA
• Pre-packing protection screening
• De-dusting of soda ash fines
• Recycle separation and size correction

For soda ash plants targeting precise 250 µm, 600 µm, and 1 mm separations, High Frequency Screens deliver repeatable, maintenance-friendly, and energy-efficient performance. Whether for protection screening or multi-stage classification of LSA and DSA, HFS technology significantly improves product quality and operational reliability.
