Scheduling in Spring with Quartz | Baeldung
The complete source code for the example is available in this github project. This is a Maven project, so we can import it and run it as-is. The default setting uses Spring's convenience classes, but we can easily switch it to Quartz API with a run-time parameter (refer to the README.md in the repository).

Principles of Screening and Sizing
• Maximum bed depth at discharge end is 4x the separation. • If too thick, probability is decreased for sized aggregate to properly stratify and pass through an opening. • Minimum bed depth is 1x the separation. • If too thin, material can bounce, stay suspended and not stratify or find an opening, thus reducing accuracy.
