Analytical methods for measuring particle distribution often differ significantly in their application and technical requirements. While independent laboratories seek high precision, the inline quality control systems engineered by FAMSUN prioritize operational speed and long-term durability. FAMSUN’s process specialists examine both laser diffraction and sieve analysis to determine which testing approach delivers the optimal value for unique quality control requirements at every feed processing plant equipped with FAMSUN production lines.
Comparison of Analytical Methods
Sieve analysis relies on mechanical vibration to pass material through a series of screens with decreasing mesh sizes. This physical separation provides a clear, weight-based distribution of particles. It remains a cost-effective method for many, though it demands manual labor and is time-consuming for large batches. In contrast, laser diffraction uses light scattering to measure particle size distributions in a liquid or dry dispersion. This method is exceptionally fast and accurate for very small particles, but the equipment cost is significantly higher.
When they evaluate milling grinding processes, they recognize that sieve analysis is often sufficient for routine quality checks. However, for research or advanced product development, laser diffraction offers a level of granularity that mechanical screens cannot replicate. FAMSUN provides insights into how these analytical choices impact the reliability of final product specifications.
Application in Lab and Production
The environment dictates the choice of technology. Quality control labs often prefer the repeatability of laser diffraction for rapid, detailed reporting. Because it generates digital data quickly, it serves as a tool for real-time adjustments. Conversely, sieve analysis remains the standard for periodic audits due to its simplicity and low maintenance.
For inline monitoring, they look for systems that provide continuous data without needing complex sample preparation. A roller grinder machine requires monitoring of the gap and roll condition, where simplified sieve-like mechanisms can sometimes be integrated for trend analysis. FAMSUN designs equipment that supports these monitoring goals to ensure consistency. By integrating the right milling grinding tools with a roller grinder machine, operations can achieve a balance between lab-grade accuracy and the practical needs of daily production.
Selecting an analytical method depends on balancing precision, cost, and the specific phase of production. While laser diffraction provides high-speed, high-resolution data for labs, sieve analysis serves as a reliable, cost-effective baseline. By aligning these tools with specific operational requirements, facilities improve their ability to verify quality and manage consistency.
