GEMCO PROCESS

설명

The General Machine Company of New Jersey (a name later shortened to GEMCO) began operations in 1916 as a general machine shop to the growing industry around Newark, NJ. In the 1930s, John L. Muench, Sr. was at a local government arsenal when he was asked about a safer machine to blend gunpowder. The double cone tumble blender was the result with the original patent being issued circa 1937.
