Keep spawners spawning?

[Nickrass]

Hello, i have a problem with spawners. I use a skeleton spawner to suply bone meal for my bread machine, but the skeletons only spawn when im close to the spawner. I tried to use chunk loaders (World Anchor, Dimensional Anchoal and Teleport Tether) to keep the spawner loaded, but that doesnt seem to work. Is there any way to make the spawners work even when im away, or do you guys know any way to automaticaly generate bone meal without the use of EE?

UU-matter will let you make bones, but...otherwise, you're kind of stuck with EE for large amounts of it. No, spawners will not spawn mobs unless a player is within a certain distance.
