Cage Mill Crushers & Industrial Pulverizers
What is a Cage Mill and How Does it Work?
Invented by Nathan P. Stedman, a cage mill is an internally fed impactor that crushes grinds or pulverizes many different materials to specified degrees of fineness.
Early cage mill crushers were used principally to crush materials that were not particularly abrasive – corn, salt, coal, clay. By 1900, Nathan Stedman had built more than 100 cage mills. After its invention, numerous applications were discovered and soon cage mills were used for crushing chemicals, clay and fertilizer materials. It wasn’t until the 1930s that the true value of cage mills as an agricultural limestone crusher, a size reduction mill and beneficiation was realized. Cage mills can be configured in two, four, and six row designs, each with their own unique crushing applications.
