Our natural stone has an approximate density of 160 lbs per cubic foot. Take your Length (L), Width (W) and Height (H) and multiply them together: (L x W x H) = Volume in cubic feet. Multiply your Volume in cubic feet by 160. This will give you the required weight in pounds. To get tons, divide this by 2000.
Determine the density of the material in pounds per cubic foot (lb/ft3). 3. Choose the idler shape. 4. Select a suitable conveyor belt speed. 5. Convert the desired tonnage per hour (tph) to be conveyed to the equivalent in cubic feet per hour (ft3/hr). (ex. 1000 tph x 2000 / 60 = 33333 ft3/hr) 6. Convert the desired capacity in cubic feet per ...

The mine was producing ore reportedly averaging $80.86 per ton in gold, with at least $50,000 worth of the ore in sight; probably tons more existed under ground that was as yet undeveloped. [ 83 ] The financial depression of 1907 did not halt work at the Lost Burro, by now regarded as one of the richest claims in the Ubehebe District.
From one to three dollars per ton was paid for drawing the ore thirteen miles to the furnace, making a sourse of income from which many settlers paid for their farms.

· Data from ''s Mining Methods booklet , abstracted here in Table 2, show that mining is associated with large volumes of waste production. The extraction of about 12 billion tonnes of ore is associated with an extraction of about 19 billion tons of waste [over 12 kg per day per citizen].
modern scientific plan" (p. 42). We found that this gang were loading on the average about 12 ½ long tons per man per day. We were surprised to find, after studying the matter, that a first-class pig-iron handler ought to handle between 47 and 48 long tons per day, instead of 12 ½ tons.
