You can create your own spawners by creating a folder in the spawners folder called "custom" where you will also find the ORE generator. You have the possibility to create other spawners like the ORE generator by copying this ORE.yml and calling it for example WOOL.yml and there you first define a crafting recipe like with ORE gen then you get the item and if you then right click on a spawners then this spawners becomes the spawners type in this case WOOL (exactly like before like with the ore spawner). And let's say you have defined in the WOOL.yml that it spawns every wool colour, i.e. this spawner only drops wool colours as an example.
