Abstract:
A method of protecting coal mill journals from abrasive wear due to impingement of coal fines includes the steps of fabricating and attaching a mild steel liner form to the journal and welding wear plates to the liner form. Welding the plates to the form can occur before and/or after the form is attached to the journal. The liner form is made up of plates providing only flat exterior surfaces.
