What is the maximum size of aggregate to use the jigging procedure?

The maximum size of aggregate suitable for the jigging procedure is specified to be greater than 1.5 inches but no greater than 5 inches. The jigging process is used for separating materials based on density, and it's most effective with this range of aggregate size. Aggregates within this size range allow for effective separation while minimizing issues related to the aggregate's weight and density during the jigging process.

Using aggregates less than 1.5 inches can complicate the jigging operation, as the smaller particles may not settle effectively in the jigging apparatus, leading to inadequate separation. Conversely, aggregates greater than 5 inches may challenge the jigging mechanism's ability to handle and separate larger sizes efficiently due to increased weight and reduced maneuverability within the jigging bed. Thus, the specified range maximizes the efficiency and effectiveness of the jigging procedure for aggregate separation.
