RPM and 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 and Associates rebuilds 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 problem 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. (Click for more ...)
RPM and Associates manufactured hardfaced overlay wear plate combines the wear resistance of chrome carbide hardfacing with
the ductility and formability of mild steel. We strictly monitor welding
parameters to ensure that customers get the highest-quality hard faced plate on
the market. RPM also cuts and forms overlay plate into finished wear liners for
any application. In other applications, RPM can apply carbide tiles to wear
surfaces. (Click for more ...)
RPM and Associates employs state-of-the-art
Laser Deposition Technology (LDT) which includes Laser Cladding
Technology (LCT), Laser Repair Technology (LRT), and Laser Freeform
Manufacturing Technology (LFMT). RPM labs have repaired hundreds of components from heavy industry
to defense and aerospace. Laser Deposition Technology (LDT) enables us to achieve a metallurgical
bond with minimal heat affect to rebuild worn surfaces to new or better-than-new
quality. Our engineers will evaluate your use environment and then prescribe the
best alloy for resurfacing your part. Laser Repair Technology (LRT) and Laser
Cladding Technology (LCT) effectively mitigate wear,
abrasion, erosion, and corrosion of parts. RPM can also build your specialty
parts with Laser Freeform Manufacturing Technology (LFMT), a method in which components are built
using CAD drawings to generate a tool path for the laser wherein a a three
dimensional part is "grown." (Click for more ...)
RPM and Associates was founded in 1982 by Rob Mudge, Deb Mudge
and Rob's parents, Jim and Phyllis Mudge. RPM and Associates 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.
In 1996, our sister company,
RPM Solutions, Inc., was started
in a joint effort with Shawn Veurink.
RPM uses chrome-carbide
hardfacing, tungsten-carbide hardfacing and laser cladding
to increase performance and provide solutions for wear in power generation
and other industrial applications. We rebuild and manufacture new coal
pulverizer grinding rolls, grinding tables, pulverizer mills, coal pipe such as elbows and
tangents, overlay plate, wear liners, and other crushing equipment used in
high-abrasion environments.
