If I destroy my blaze spawner in minecraft ps3, will they still spawn?

I've been playing minecraft for awhile and i decided to get it on ps3. I was playing it one day and my friend joins and destroys my blaze spawner. I've search all around the nether to find another one and I can't find one, EVEN in the nether brick place (forgot the name) and I really wanna find out if they can just spawn randomly or can I do something to spawn at a different nether place? All I need to do is get more blaze rods (because I wasted them on brewing stands) to create some eye of Enders so I can find end portal, defeat the dragon and obtain my platinum trophy!

Blazes can spawn in the nether fortress without a spawner but they will be much harder to find.

No they won't spawn from the spawner and they may spawn rarely naturally. I would just go into creative and spawn a couple in since it wasn't your fault, if you want future achievements(That's on XBOX don't know what there called on PS3) from that world don't do it though it will disable them on that world only though.
