U.S. Bureau of Mines Develops Portable Crusher for Underground Hardrock Mines.
Eng and Min J 1982 Jan; 183(1):72-75
The high cost of materials-handling in most underground hardrock mines prompted the Bureau of Mines to develop a portable, low- headroom crusher. This equipment can be positioned close to the face to allow the operation maximum utilization of low-cost conveyor haulage. The unit was successfully tested in a limestone quarry, and a long-term production test is planned.
