Resultant Definition and 512 Threads

Hmm. I'm quite confused with this: Does no resultant force means no external force? i.e. if there is an external force, there is a resultant force? Like say, sand falls onto a moving conveyor belt at the rate of 5.00 kg/s. The conveyor belt is supported by frictionless rollers and moves...
