Description

AZA 0926 Sieve Shaker ‘Gyratory’: Precision Particle Size Analysis for Diverse Materials by Azalab

The Azalab AZA 0926 Sieve Shaker ‘Gyratory’ is an advanced laboratory instrument designed for the highly efficient and accurate determination of particle size distribution of various dry granular and powdered materials. Unlike conventional vibratory shakers, the gyratory motion, often combined with a tapping action, provides a superior method for separating particles. This makes the AZA 0926 particularly effective for materials that are prone to agglomeration, static charge, or have a wide range of particle sizes. It is an essential tool for quality control, research, and development in industries such as civil engineering (aggregates, soil classification), cement and concrete, mining, pharmaceuticals, food processing, and chemicals across India.

The effectiveness of a sieve shaker largely depends on the motion imparted to the test sieves. The AZA 0926 Sieve Shaker ‘Gyratory’ utilizes a sophisticated motion profile:

1. Gyratory (Orbital) Motion: The sieve stack is subjected to a horizontal circular motion. This causes the particles to spread evenly across the sieve mesh and roll over the openings. This action continuously presents different orientations of the particles to the mesh, significantly increasing the probability of passage for correctly sized particles and preventing ‘blinding’ or clogging of the sieve apertures.
2. Tapping Motion (often integrated): In addition to the gyratory motion, an intermittent vertical tapping action (similar to a hammer striking the sieve stack) is often incorporated. This helps dislodge particles that may have become stuck in the mesh openings due to their shape, surface tension, or electrostatic forces, further aiding in the passage of finer particles and ensuring complete separation.

This combined motion is crucial for achieving highly reproducible and accurate results, especially for materials that are challenging to sieve efficiently with simple vibratory actions. It ensures that particles are continuously reoriented and presented to the sieve openings, leading to a more thorough and faster separation process.
