Some relevant fa ctors were consider ed in the design and development of the crusher; suc h fac tors are cost of maintenance power requirement and ease of replacement of various componen ts and
Boom and crash indices are known for their sudden spikes Hikes and drops occur rapidly and can be as big as 50 pips The boom phase occurs when an upside spike results in sudden price increases The crash phase is when prices decrease extremely fast
The algorithm can yield reproducible Bond work indices fast with negligible computational errors The algorithm s applicability was validated against the experimental Bond tests on different ore
Information Gained Effect on Circuit Selection Preliminary drill core for resource definition and split for bond work indices Whole core for Autogenous Media Competency Index Lower installed cost than a Gyratory crusher Can handle high abrasion with low maintenance Can handle tough crushing application upto 600 MPa nickel ores
Operational Costs Operational costs encompass the expenses incurred during the day to day use of the crusher These costs mainly consist of fuel or electricity consumption regular maintenance spare parts and consumables such as lubricants It is important to consider the type and capacity of the crusher as well as the expected utilization
