We don’t claim to be real knowledgeable on this subject and have had only limited involvement in parts for this application. You’ll likely find that the way they go about reduction of coal differs considerably from aggregate producing. The sizing requirement you’ve noted, is over an 18:1 ratio. Primary jaw & gyratory crushers are effective only to half that kind of reduction, & wouldn’t come near getting down to the finish size product required. We’ve made parts for some multiple stage varying toothed roll crushers that are sometimes used in the crushing of coal. They’re multi-staged, to the point of 3 or more levels of coarseness, within the same machine, to allow getting to the sizing you’ve noted. They’re certainly not oriented towards wear life efficiency. Some of the ones we’ve provided allowed only a 10 to 15% wear material ratio to the casting carcass. They are very expensive pieces of equipment, to own and operate. A couple OEM crusher manufacturer names you might look into would be Krupp-Polysius and McLanahann. We’ve not had enough to do with these kinds of machines to be of much detailed help. Good luck in your search.
