AISI | Electric Arc Furnace Steelmaking

The number of charge buckets of scrap required to produce a heat of steel is dependent primarily on the volume of the furnace and the scrap density. Most modern furnaces are designed to operate with a minimum of back-charges. This is advantageous because charging is a dead-time where the furnace does not have power on and therefore is not melting.

Ball Mill Loading - Dry Milling - Paul O. Abbe

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

Rod mills, how they function - Mine Engineer.Com

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

Calculating Timber Prices: A Formula For Sawmills

For a rough idea, start by adding 50% to 70% to your cost figure (excluding timber) of $450. You can then subtract that total from the estimated price you can charge for lumber ($800 in our above equation). For example: $450 x 1.5 = $675 per thousand board feet. $450 x 1.7 = $765 per thousand board feet.
