Computing Average Unit Costs Assume The Total Monthly
At $2.50 per ton it takes 2,320 tons per month. In our earlier scenario, to pay for that extra $300,000 for the crusher takes 9.7 tons per hour! This is a very achievable gain. In fact, getting an additional 25 tons per hour is easily attinable when you include liner performance and crushing chamber automation.May 11, 2017 For the example cited, a mining advance rate of 100 feet per month would require a (single) crusher moveup every four months. Site preparation should, of course, be kept to a minimum but with only four month’s tonnage over which to amortize its cost, the required minimum, for all pratical purposes, is virtually zero.
