Mill performance is based on mill diameter and length only increases or decreases capacity. The Slice Mill is simply a mill of the same diameter as the production mill but much shorter. A Slice Mill of 72 diameter by 12 wide would replicate the result of a normal production, mill 72 in diameter as 120 long.
6. Convert the desired capacity in cubic feet per hour to the equivalent capacity at a belt speed of 100 fpm. (ex. Capacity (eqiuv) 33333 x (100 / 600 fpm) 5555 ft3/hr 7. Find the appropriate belt width 8. Selected belt speed may require revision Coal, anthracite, sized 27 Coal, anthracite, sized 55-60 1 lb 0.4536 kg 1 ft3 3 0.0283 m
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 tractor 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.
