The approximate running costs for crushing plants of different capacities up to 4,000 tons per day on the basis of an eight-hour crushing day are easy to calculate. The figures must be regarded only as a rough guide to the average costs of modern installations ; they are direct costs and include no overhead charges.

This number can be converted to the number of hours per hectare of subgrade. For example, a 120 hp grader may require about 10 hours of productive machine time without delays per hectare of subgrade or 0.1 hectares per hour. The production rate for final grading of a 6.0 meter subgrade would then be, P = (0.1 ha/hr)/(0.6 ha/km) = .17 km/hr

Man-Hour per Unit: (10 x 8) / 500 = 80/ 500 = 0.16 h (9.6 minutes) Hence, it takes 0.16 man-hours per unit to produce a piece of product ( for such a low figure it is assumed that machinery is in place to produce the product in mass, at a fast rate).

Determine the net production rate in tons per hour. Multiply the net production rate (LCY per hour) by the material weight (tons per LCY). Divide the material weight by 2,000 to convert pounds per LCY to tons per LCY. Material weight (tons per LCY) = weight (pounds per LCY) / 2,000 pounds per ton

"We know that a 440-ton machine will generate more revenue than a 40-ton machine, but it also consumes more of everything per hour," explains Larson. "And when we’re carrying debt, the 440-ton has a higher debt load. It might be generating $100/hour of revenue, whereas the 40-ton might be generating $40/hour."

Essentially, excavator productivity is typically measured by the volume of loose or rock soils the machine can displace in a hour of continuous operation. Understand the formula for calculating excavator productivity. The formula is as follows: Q = (60*q*z*n*kf) / kl, where Q is the productivity of the excavator, q is the capacity of each rotor bucket in cubic feet, z is the number of buckets

ok as tmshucks pointed out. to convert an excel time to decimal time you multiply by 24 ,format cell as general. 13:30 becomes 13.5. so if 13:30 produced 13.5 units would = 1 per hour. however the rules of algebra come into play. =B1/A1*24 would give in this case 576 because the division would take place first ie = (B1/A1)*24.

Formula for Crushed Stone for a Project. (L'' x W'' x H'') / 27 = cubic yards of crushed stone needed. In the construction world, most materials are measured in cubic yards. Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This number is how many cubic yards of crushed stone you need.

BSG has found the best way to measure costs and assign a “productivity value” to a machine is by using the cost per ton metric. We’ve found this metric most useful because it includes all associated costs of running a machine on an hourly basis and compares that to the amount of material (tons) the machine is producing on an hourly basis.

For example, in felling, the power saw rarely works more than 4 hours per day, even though the cutter may work 6 or more hours and may be paid for 8 hours, including travel. If felling production rates are based upon a six-hour working day, with two hours of travel, the machine rate for an operator with power saw should consider 4 hours power saw use and eight hours labor for six hours production.
