Why should the slat conveyor not continue running during mix discharge after a truck leaves?

The slat conveyor should not continue running during mix discharge after a truck leaves primarily because having it operate during this time can lead to material segregation. When the conveyor keeps running, the mix can be agitated and moved in a manner that causes the heavier components to settle or separate from the lighter ones. This segregation can negatively affect the quality and uniformity of the material being discharged, leading to inconsistencies in the final product. Ensuring that the conveyor does not operate during the mix discharge helps maintain the integrity of the mix, ensuring that the materials remain thoroughly combined and mixed as intended.

Options that suggest increased speed of operation, less wear on the conveyor, or maintaining a steady flow do not address the specific concern of limiting material segregation, which is crucial for quality control in the mixing process.
