The gyratory sieve shaker (motorized type) is widely used in laboratory and industrial environments, primarily for granulometric analysis and mechanical screening applications. This process enables accurate determination of particle size in heavy solid materials and bulk samples.
During operation, the sample is placed on a stack of granulometric test sieves where mechanical sieving is performed. To improve efficiency, the sieve shaker acts as a material separator and classifier, commonly referred to as a gyratory motion sieve shaker. It generates a controlled upward and downward gyratory movement, which significantly enhances sieving speed and accuracy.
The gyratory sieve shaker is designed for simple and efficient operation, allowing separation based on particle geometry. It ensures secure fixation of sieves while enabling quick removal and replacement. The gyratory drive mechanism produces a distinct vertical motion pattern that distributes material evenly across the sieving surface, improving screening effectiveness.
Working Principle
- Sieve Stack Arrangement:A series of standard test sieves with progressively decreasing mesh sizes is arranged in a vertical stack. The sieve with the largest mesh opening is placed at the top, followed by finer sieves in descending order. A collecting pan is positioned at the bottom to gather particles smaller than the finest mesh size.
- Sample Placement:The material sample to be analyzed is evenly distributed on the topmost sieve. The sieve stack is then securely clamped to prevent movement during operation, ensuring stability and consistent screening.
- Gyratory Motion Generation:Once the shaker is switched on, the internal gyratory drive system generates a circular horizontal motion combined with a gentle upward and downward movement. This unique motion causes particles to continuously move across the sieve surface rather than remaining stationary.
- Particle Stratification and Separation:The combined motion helps particles reorient and stratify according to size. Smaller particles find openings in the mesh and pass through to the next sieve, while larger particles remain on the current sieve. This stratification improves separation efficiency and prevents clogging of sieve apertures.
- Uniform Distribution of Material:The gyratory movement spreads the sample evenly over the entire sieve surface, allowing maximum utilization of mesh area. This ensures accurate and repeatable particle size analysis.
- Controlled Operating Parameters:The shaker allows independent adjustment of operating time, motion intensity, and vibration mode. These parameters can be optimized based on the type of material, particle size range, and applicable testing standards.
- Collection and Analysis:After the preset operating time, the shaker stops automatically. Each sieve is then removed and the retained material is weighed or examined. The collected data is used to calculate particle size distribution and material classification.
