A rock crusher is a crusher designed to take large rocks as input and to produce small rocks or rock dust as output. They are used to produce rock fill material for such uses as landscaping and erosion control.
They are typically very large, very loud, and produce a considerable quantity of dust. Most installations are therefore in rural areas.
RockCrusher was on the Atchison, Topeka and Santa Fe Railway near the Bachelor Prong of Hords Creek, eight miles northwest of Coleman in northwestern Coleman County.
The rockcrusher was a large roller powered by a steam engine and housed in a tall building.
The RockCrusher post office operated from 1912 to 1914, at which time the community had an estimated population of 400, two general stores, and a cotton gin.
