What is the typical requirement for sample size in a mechanical shaker?

The requirement for sample size in a mechanical shaker is typically 2-3 kg. This sample size is considered optimal for ensuring that the mechanical shaker can effectively separate the aggregate particles during the analysis. Using a sample within this range allows for sufficient material to be tested, which promotes accurate and reproducible results when performing gradation analysis or other aggregate assessments.

Choosing 2-3 kg balances the need for a representative sample while avoiding excess material that may complicate the testing process or exceed the shaker's capacity. A smaller sample might not provide reliable information about the overall material properties, while a larger sample could waste resources and time without significantly improving the results.

This understanding is crucial for technicians conducting tests, as it ensures that the mechanical shaker operates efficiently, providing relevant data for quality control and assurance in aggregate production.
