I'll never have enough steel for one of those ships and I don't really care about the research bureau, grinding these ship lines once was enough. Coal ships are the only ones I'm likely to get and therefore, for me, using steel on them to get them sooner is a far better return on my time than waiting 5 years to, maybe, get one steel ship.
A Comparison of Three Types of Coal Pulverizers
It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a centrally located feed pipe to the center of the grinding table.
