RPM & Associates manufactures and rebuilds coal pulverizer parts for Combustion Engineering, Foster Wheeler, Babcock & Wilcox, and Alstom bowl mills. Our mill body wear liners, deflector liners, journal liners, and pulverizer rolls are engineered to offer the longest wear life with the lowest risk of catastrophic failure. We'll even rebuild your worn journals to perform better-than-new due to design advancements made by our own engineers. RPM strives to lower your risk of grinding mill parts failures while extending your operation cycles.
RPM & Associates, Inc. was founded in 1982 by Rob Mudge, Deb Mudge and Rob's parents, Jim and Phyllis Mudge. RPM & Associates, Inc. is a manufacturing firm located in Rapid City and is a South Dakota corporation. Our core customers are coal fired power plants, mining operations, cement plants, chemical processing plants, Department of Defense and aerospace. We are focused on solving wear problems for our customer base using innovative ideas, automatic welding systems, creative machining and proper material selection.
Let RPM & Associates rebuild your worn coal pipe and elbows with our proven chrome carbide overlays. Welded elbows and tangents provide great coal flow and long wear life without the weight or adhesion problems of ceramic tiles. Our long-lasting, abrasion-resistant hardfacing can be applied to coal transporters from 3" to 28" diameter, and up to five times the centerline radius size. We also manufacture and rebuild ash spools, riffle housings, and a variety of other pipe-related parts used in high-abrasion environments.
From mine to mill, RPM can manufacture or repair your high-wear parts for maximum wear resistance with minimal down time. But we don't just repair or replace, we analyze your specific wear environment to determine what materials are needed to achieve an improved wear life of your part and the most cost-effective solution to your wear problem. Whether they are rolls, tables, wear liners, chute liners, or journal assemblies, RPM has the ability to repair and reline with hardface welding on CE, MPS, FW, B&W, or hammer mills.
