Crushing Plant Capacity - Mineral Processing Metallurgy

Mar 19, 2017  Underground mining operations without surge capacity ahead of the primary should be figured for at least 25% reserve. The average gravel plant usually has some surge capacity between the pit and the primary crusher; in many instances, however, this surge is so small that it cannot be counted on to smooth out protracted delays in the pit.

Mining Methods VS Underground Crusher Location

Other crusher parameters (feed opening, for instance) depend on specific mining conditions, and are discussed elsewhere, as in the handling of oversize in conjunction with crusher operation. This mine group does, however, offer the possibility of handling oversize at any location in the mining section, including (if absolutely necessary) at the ...
