I make lots of pizza for fun with some friends at hacker events. We've managed to do ~120 portions (not individual pizzas) an hour with an entry-level pizza oven (2 levels, 60x90cm² area), the kind you see at kebab shops, and the oven was quite far from being the limiting factor (rolling the dough is hard work). From a quick web search, conveyor ovens can do up to 150 pizzas per hour, and you can typically stack them three high. So shouldn't be a problem. The trick is that pizza is baked at a very high temperature. Our oven goes up to 500°C (900°F). Baking time is 90s-2min if you put the pizza on the fire stones directly, or ~3mins if you use a screen (tray).
