What should the adjustable chutes on a coarse aggregate mechanical splitter be set to?

The adjustable chutes on a coarse aggregate mechanical splitter should be set to about 50% larger than the largest particles. This setting allows for effective splitting of the aggregate while ensuring that larger particles can pass through without getting trapped or obstructed. It also facilitates an efficient and consistent splitting process, which is crucial for obtaining representative samples for testing.

Setting the chutes to this specific dimension helps to maintain the integrity of the sample being taken. If the chutes are set to equal the largest particle size, there is a risk that some particles might not be split adequately, leading to an unrepresentative sample. Meanwhile, setting the chutes significantly larger than all particles could lead to excessive fragmentation and loss of larger aggregates, which would adversely affect the test results.

Thus, adjusting the chutes to approximately 50% larger than the largest particles strikes a balance that allows for efficient aggregation splitting while capturing the necessary particle sizes for accurate testing results.
