About High Frequency Screen in sand

With increasing restrictions on natural sand mining, manufactured sand (M-Sand) and plaster sand (P-Sand) produced from crusher dust have become essential for the construction industry. High-frequency screening technology plays a critical role in converting crusher dust into usable, graded sand meeting IS standards.

Crusher dust contains excess fines that negatively affect concrete strength and workability.
High-frequency screens generate rapid vibration that efficiently separates micro-fines, ensuring compliance with IS 383 grading requirements.

The high-frequency, low-amplitude motion enables accurate size classification, producing:

• Well-graded M-Sand for concrete
   
• Fine, uniform P-Sand for plastering
   

This consistency improves cement consumption efficiency and surface finish.

Controlled particle size distribution enhances:

• Compressive strength
   
• Workability and pumpability
   
• Reduced segregation and bleeding
   

Result: stronger and more durable concrete.

Unlike conventional screens, high-frequency screens recover maximum usable sand from crusher fines, reducing waste and increasing overall plant recovery.

Crusher dust often contains moisture, causing blinding on normal screens. High-frequency vibration:

• Prevents screen choking
   
• Maintains open apertures
   
• Ensures continuous operation even with damp feed
   

High-frequency screens provide higher screening area efficiency in a smaller footprint, making them ideal for:

• Retrofit plants
   
• Space-constrained quarry sites
   

Lower power consumption translates into reduced operating cost.

The gentle stratification mechanism minimizes abrasion on screen media, extending screen life and reducing maintenance downtime.

Properly graded M-Sand and P-Sand produced using high-frequency screens meet:

• IS 383
   
• IS 1542 (Plaster Sand)
   

This improves acceptance by RMC plants, infrastructure projects, and government works.
