Crusher

The crusher will destroy any item inserted into it immediately.

Crusher

All it has is a belt, with a AutoExtractionNodeAction at the end, which is a default action included in the plugin, with the following code:

};

UAutoExtractionNodeAction::UAutoExtractionNodeAction()
{
	SetBehaviour(EConveyorActionBehavior::Process
				| EConveyorActionBehavior::Async);
	bIsStateless = true;
#if WITH_EDITORONLY_DATA
	Icon = GetExtractionIcon();
#endif
}

void UAutoExtractionNodeAction::ProcessItem_Implementation(FConveyorItem& Item, const FConveyorNodeHandle& Node, bool& ShouldItemProceed)
{
	Item.Invalidate();
	ShouldItemProceed = false;
}

If you’re unfamiliar with C++, it sets the Process behavior on and overrides the ProcessItem function. All this function does is invalidate whatever item is passed.
