The current transfer chute design in the Eurosilo is a rockbox chute wherein the material forms a bed of particle with a slope and the material starts sliding beyond the slope. The rockbox chute is preferred when the material is very abrasive or for transfers with high rate of discharge when the chute material is expected to wear off quicker.

This allows the user to simulate chute buildup during emergency stops, and then analyze how the transfer chute will respond when the conveyor restarts. These features allow the engineer to focus on the detail engineering (e.g. transfer chute design), rather than getting bogged down creating belt feed points and other required DEM details.
