ASTM A01 and B02 standard committees, I knew all too well the many pitfalls and challenges of writing such a handbook. There were many steel standards from around the world that were new to me, which created far too many surprises and delays in completing this book.
The grindability test (ASTM D409, ISO 5074) uses a ball-and-ring type of mill in which a sample of closely sized coal is ground for a specified number (usually, 60) of revolutions. Then the ground product is sieved and the grindability index is calculated from the amount of undersize produced using a calibration chart.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size
Weight of Steel bars size 8mm,10mm,12mm, Calculating 8mm Steel rod weight per metre we used the formula D^2 L/162 If dia of steel = 8mm, length of 1 steel rod = 12 meter, then weight of 1 piece of 8 mm steel rod in kg = (8×8×12)/162 = 4.74 kgs, so weight of 1 piece 8mm Steel rod is 4.74 kgs. Ans :- 4.74 Kg is weight of 1 piece (12m) 8mm Steel ...
