Hosokawa Micron Powder Systems is an American enterprise located in Summit, New Jersey that specializes in the design and production of machinery for the reduction, classification, and blending of powders used in chemical, pharmaceutical, and food industries. Originally founded in 1923 by Louis Ruprecht under the name Pulverizing Company, it became part of the Hosokawa Micron Group in 1985.
History
In 1923, Louis Ruprecht, an alumnus of Stevens Institute of Technology, launched Pulverizing Company with headquarters in New York City and a manufacturing facility in Elizabeth, New Jersey. The firm concentrated on micronizing powdered substances and developed its inaugural patented device—the Mikro-Pulverizer—which utilized mechanical impact through hammers and screens to decrease particle size.
As the company expanded beyond its Elizabeth location, it moved to Roswell Park in 1932 and later settled in Summit, New Jersey, in 1942. During the Second World War, it provided essential materials to the US Army and Navy for armored vehicles, naval vessels, and aircraft, including producing more than one million pounds of magnesium powder used in tracer ammunition and signaling flares. The Summit site was under strict security measures throughout this era.
After the passing of Louis Ruprecht in 1954, ownership transferred to Metals Disintegration Company. Following multiple changes in proprietorship, the Micron Powder Group acquired the business in 1985, rebranding it as Hosokawa Micron Powder Systems. Today, it operates from a 14,000-square-foot plant located in Summit.
