Portable Rock Crushers in Underground Mining

2020-02-10
[Portable" in Portable Rock Crushers simply means that the crusher is moved periodically in order to be close to production, thus minimizing costly haulage of run of mine material. Within this simplified definition however, portability has quite different meanings in mines of widely varying ore bodies and mining plans. We shall further assume that a portable crusher is one that can be moved through standard mine passageways with minimal dismantling, and can be set up with little or no site excavation.

[Hard-rock" is sometimes taken to mean [non-coal", but this broad definition would include many weaker mineral mines not in need of the fundamentally new equipment that is the subject of this study. Many of these non-coal mines have, however, developed highly efficient and mechanized coal-like mining methods that would be applicable to hard-rock mines if suitable equipment (crushers) were available. We have therefore gained valuable information by studying these mines, but the intended beneficiary of this investigation is the underground [hard-rock" industry, defined as those mines that cannot economically make use of presently available portable underground crushers.


The basic portability concept under investigation here might better be described by the phrase "decentralized crushing to allow automated ore haulage". Clearly this means more and smaller crushers exhibiting some degree of mobility, and automated ore haulage usually means belt conveyors. The trade-off is a necessarily more costly crushing system against a more efficient and productive ore handling system. From the crusher manufacturer`s point of view the challenge is to achieve small size and portability without sacrificing too much in the important areas of feed opening, throughput, system availability, and capital and operation costs.
