Five tons per hour of limestone undergoes size reduction passing through a crusher with a surface area of the feed and the product of 100 and 200 m2/kg respectively Calculate the required power to crush the limestone assuming to apply Rittinger s Law having a Rittinger s number of m2/J
·Q = Capacity tons per hour π = Pi approximately D = Roll Diameter meters W = Roll Width meters S = Roll Speed revolutions per minute ρ = Bulk Density of the Material tons per cubic meter Example Solve Let s calculate the capacity of a roll crusher with the following specifications Roll Diameter meters; Roll Width
Purchase Price The upfront cost of purchasing the crusher Depreciation Spread the purchase price over the projected lifespan of the crusher to determine the annual depreciation cost 2 Operating Costs Fuel/Energy Consumption Calculate the amount of fuel or electricity required to run the crusher Multiply by the cost per unit of fuel or
·Like the jaw crusher the cone crusher provides a relatively low cost crushing solution but there are application drawbacks that may make another crushing solution more appealing First cone crushers cannot accept all material sizes Any material fed to the crusher must be pre sized for that particular crusher usually 200mm or less
Let s illustrate the Roll Crusher Capacity calculation with an example Suppose we have a roll crusher with the following parameters Roll diameter R = meters; Roll length L = 1 meter; Set S = meters; Peripheral velocity V = 2 meters per second; Tonnage rate T = 10 metric tons per hour; Hardness H = 200 MPa; Using the
·Jaw Crusher Size Recommended Feed Size Capacity In Tons Per Hour With Jaw Setting Of Drive Approx Wgt In Kgs MM Inches MM MM 13 20 25 31 37 50 62 75 87 100 125 150 175 The output in tons indicated is based on average hard dry quartz or similar rock weighting at least 100 lbs per cubic ft when crushed and
