However, Allis-Chalmers, for many years, was synonymous with mining, mineral and food-grade machinery, producing materials that you rely on daily. For instance, Allis-Chalmers identified demand in many industries for machinery that agglomerated or crushed over- and under-sized product.
The Early Stages of Our Story
Allis-Chalmers Corporation was formed in 1901 by merging the Edward P. Allis, Fraser & Chalmers, and Gates firms. In addition, headquartered in Milwaukee, WI USA, it employed tens of thousands of people and was a massive conglomerate for industrial equipment. However, it underwent a series of divestitures in the 1980s.
Rugged, Reliable Machines
Allis-Chalmers machines that compacted material were classified as compactors and briquetters. Comparatively, crushing machines were known as roll crushers or granulators and flake breakers. Furthermore, machines that flake grains and other material took the names flaking mills and shredding mills. These machines have maintained their names, but have evolved tremendously over the years. Moreover, Allis-Chalmers began manufacturing these simple, robust machines with counter-rotating rolls, near the beginning of the 20th Century. Rolls compress or crush material to achieve the best solution for each end-use.
Known for technology and innovation
Allis-Chalmers developed the first roll compactor, during the 1920s. The company was synonymous for its inventiveness; in like manner, Nikola Tesla, famed inventor and engineer, worked for Allis-Chalmers in Milwaukee, WI USA from 1919-1922.
Uniquely, Allis-Chalmers and Ludman have produced equipment to process these and many more applications, over the years:

Story of Ludman's Evolution
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.
Ludman not only builds custom machines for agglomeration and size reduction
