Crushing do's and don'ts : Pit Quarry - Operations

04-01-2016  “The quality of the rock will affect operating costs,” Dobler says. “If an operation isn’t double-checking work indexes and abrasion indexes, they can get caught by surprise when wear parts wear out faster.” Producers typically take core samples before quarry operations begin, but testing should never stop because initial core drilling was done.

Crushing Equipment Purchase Price Means Less

Here’s the math. Let’s take a mid-sized crushing operation and try to quantify these costs. Assume: • 250 tons per hour production • Crushing price of $2.50 per ton • 3 crew members on shift, average hourly wage $20 per hour • 60 hours per week operation • Crushing season 26 weeks or 130 Days – Approximately 6-7 months of operation

3. CALCULATION OF MACHINE RATES

3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a Pulverizer with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.
