What should the width of the chutes be for a mechanical splitter?

The width of the chutes for a mechanical splitter must be at least 50% larger than the largest particle size to ensure effective splitting and handling of the aggregate sample. This adequate width allows for the passage of larger particles without blockage or buildup, which can lead to misrepresentation of the sample. Ensuring the chutes are sized correctly prevents issues such as segregation during the splitting process, where larger particles might be disproportionately retained in one chute while smaller particles are allowed to pass through.

Choosing a width that is too narrow, as suggested by some incorrect options, could result in mechanical issues or inaccurate sampling. For instance, if the chutes were equal to the width of the conveyor belt, it might not accommodate the largest particles effectively. Standardizing to one inch does not consider the variability in particle sizes across different aggregates, while making the chutes smaller than the smallest particle would clearly obstruct flow. Therefore, having chutes that are at least 50% larger than the largest anticipated particle size is essential for maintaining accuracy and efficiency in the sample preparation process.
