Ludman Industries & Allis-Chalmers History

When you think of Allis-Chalmers (A-C), you may envision a bold orange tractor plowing a cornfield or the unmistakable historic A-C logo.

However, Allis-Chalmers, for many years, was synonymous with mining and food-grade machinery, producing materials that you rely on daily. A-C identified demand in many industries for machinery that agglomerated or crushed over- and under-sized product.

Allis-Chalmers Corporation was formed in 1901 by merging the Edward P. Allis, Fraser & Chalmers, and Gates firms. Headquartered in Milwaukee, WI USA, it employed tens of thousands of people and was a massive conglomerate for industrial equipment, until it underwent a series of divestitures in the 1980s.

Allis-Chalmers Machines that compacted material were classified as compactors and briquetters, crushing machines were known as roll crushers or granulators and flake breakers, and machines that flake material were identified as  flaking mills and shredding mills. These machines have maintained their names, but have evolved tremendously over the years. A-C began manufacturing these simple, but robust machines with counter-rotating rolls to compress or crush material to achieve the best solution for each end-use, near the beginning of the 20th Century.

Allis-Chalmers developed the first roll compactor, during the 1920s. The company was synonymous for its inventiveness; Nikola Tesla, famed inventor and engineer, worked for Allis-Chalmers in Milwaukee, WI USA from 1919-1922.

Ludman Machine Company was founded in the USA by immigrant machinist Louis Jakober in 1968 to perform subcontract work for Allis-Chalmers’s Mining and Food Divisions. Ludman purchased product lines from these divisions in 1986 and has continued to build upon the robust tradition of manufacturing rugged and reliable agglomeration and sizing equipment for many industries.

President & CEO James P. Lenahan changed Ludman Machine Company’s name to Ludman Industries in 2011 to match his vision for the company. Ludman Industries provides complete turnkey system process solutions for compaction plants, in addition to designing, building and servicing OEM compactors, briquetters, flake breakers, granulators, flaking mills, and shredding mills.
