Hosokawa Micron Powder Systems is an American company located in Summit, New Jersey, which designs and manufactures equipment for size reduction, classification[1][2] and mixing[3] of chemical,[4] pharmaceutical[5] and food materials.
In 1923 Louis Ruprecht, a graduate from Stevens Institute of Technology, founded Pulverizing Company with offices in New York City and a small machine shop in Elizabeth, New Jersey.
The first machine patented was the Mikro-Pulverizer which accomplished powder size reduction by mechanically impacting material with the use of a hammer and screen.
In ten more years the company had once more outgrown these facilities and moved to Summit, New Jersey where it currently resides.
In May, 1942 the Summit location opened and was immediately contracted by the US Army and Navy to produce materials for World War II.
