BALLAST SIEVE – 100 x 70 x 10 cm – 65 mm AZA1299

Description

Purpose & Importance of Ballast Sieving

In infrastructure projects—particularly railway tracks, roadbeds, and foundations—aggregate size distribution directly affects drainage, load distribution, compaction, and long-term stability. Oversized or improperly graded ballast can lead to premature structural failure.

The 65 mm aperture of the AZA1299 sieve is specifically selected to evaluate coarse material limits, ensuring that oversized stones are identified and removed in accordance with specification requirements.

Robust Construction & Design

The AZA1299 features a heavy-duty welded frame measuring 100 × 70 × 10 cm, providing a large sieving surface for efficient processing of bulky samples. The frame and mesh are manufactured from galvanized steel or stainless steel, offering excellent resistance to corrosion, abrasion, and deformation.

Construction Highlights

• Reinforced welded frame for structural rigidity

• High-tensile square wire mesh with 65 mm apertures

• Securely welded or fixed mesh to withstand repeated impact

• Open mesh design to prevent material clogging

• Reinforced edges to prevent warping and tearing

This construction ensures consistent performance even when handling sharp-edged, high-mass aggregates.

Versatile Operation

The AZA1299 Ballast Sieve is suitable for both manual shaking and mechanical sieve shaker systems, depending on site or laboratory requirements. Its rigid structure allows it to remain stable during aggressive handling and high-load screening operations.

The sieve is also stackable when used with compatible ballast or aggregate sieves, allowing users to build a full particle size distribution stack for comprehensive sieve analysis.

Applications

The AZA1299 is widely used across multiple sectors:

• Railway Infrastructure & Maintenance – Ballast grading and acceptance testing

• Road & Highway Construction – Coarse aggregate evaluation

• Civil Engineering Test Laboratories – Material classification and compliance testing

• Mining & Quarry Operations – Primary aggregate screening
