Founded in 1979 by David H. Miles and his father, William F. Miles, Process Machinery Inc. was built from the ground up based off a need for a full service provider in the aggregate market. The company is currently owned and operated by the third generation, Daniel Miles and Jennifer Miles Ratterman.  We operate from a 100,000 sq ft manufacturing building in Shelbyville, KY, that is equipped with state of the art fabrication and processing equipment. In our almost 45 years of operation, we have grown from a small fabricator, to a full service dealer and manufacturer of aggregate processing plants.  We employ licensed Professional Engineers to design and create the plant YOU need to maximize production and decrease downtime.  We offer creative solutions catered to your plant, your needs and your production.  We are not a cookie cutter plant provider.  If you want a maximum performance plant that operates with the highest cost efficiency and most importantly, delivers on time, on schedule, call PMI.
