Description

The apparatus operates on the principle that unstable soil aggregates disintegrate more readily in water compared to stable aggregates. The procedure involves:

1. Filling 8 sieves (each with a 60-mesh screen and 0.250 mm openings) with soil aggregates.
2. Immersing the sieves in water-filled cans mounted on a shaking machine.
3. Oscillating the cans up and down for a fixed duration to simulate water-induced breakdown of aggregates.
4. Collecting disintegrated aggregates in water-filled cans beneath the sieves.

Following this initial phase, the cans are replaced, and remaining aggregates are destroyed, leaving behind sand grains and plant roots. After drying the cans, the stable and unstable aggregate weights are determined. The aggregate stability index is calculated by dividing the weight of stable aggregates by the total aggregate weight.

Standard Set Includes:

• Shaking machine for wet sieving (110-240 VAC, 50/60Hz adapter included)
• 8 sieves (Ø 39x39 mm, 0.250 mm opening, 10.2 cm² surface)
• Stainless steel sieve cans (Ø 64x45 mm)

Optional Accessories:

• Sieves with various openings (2.0 - 0.045 mm)
• Electronic Pocket Balance for precise weight measurements

The Wet Sieving Apparatus is an indispensable tool for soil stability and erosion research, enabling reliable and repeatable laboratory analysis of aggregate behavior under water stress conditions.
