High Frequency Screen for Sand Production

Why Use High-Frequency Screens for M-Sand Production & P-Sand Production

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 that meets IS standards.

1. Precise Removal of Fines (<75 Microns)

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.

2. Sharp & Consistent Sand Grading

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.

3. Improved Concrete Performance

Controlled particle size distribution enhances:

- Compressive strength

- Workability and pumpability

- Reduced segregation and bleeding

Result: stronger and more durable concrete.

4. Higher Yield from Crusher Dust

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

5. Effective Handling of Moist & Sticky Material

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

6. Compact & Energy-Efficient Design

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 costs.

7. Lower Wear & Maintenance

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

8. Compliance with Standards & Market Acceptance

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.
