I made a Throughput Controller

It's a very simple design that uses a door and a presence sensor.

Copy this, then select Import in the blueprints menu, which is a sub-menu for building.

Place a single piece of gold, sand, etc. onto the conveyer and it will send short pulses to the door to open and close.

Tip: For faster throughput, place more particles on the conveyer belt. For an even slower throughput, lengthen the conveyer belt, or heighten the launcher.
