Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.

Koppers is a legacy equipment brand originating in the United States. Its range includes ball mills. The grinding mill business is within Metso's legacy service scope. For spare and wear part identification, visit the related brand metso page, or send the equipment nameplate, model and drawings directly.
Brand relationships help identify current and historical installations. They do not imply authorization, affiliation or trademark endorsement. Spare part manufacture depends on the specific machine model, serial number, drawings and physical interfaces.
Koppers is a historical US mineral-processing equipment name linked to the Hardinge, MPSI and Svedala grinding businesses. Its equipment includes ball and rod mills, Cascade autogenous and semi-autogenous mills, and early Tower Mills. The legacy grinding installations are supported within the Metso portfolio; this equipment history is distinct from the present-day Koppers chemicals and treated-wood business.
