## Rod Mill an overview | ScienceDirect Topics

In the rod mill, high carbon steel rods about 50 mm diameter and extending the whole length of the mill are used in place of balls This mill gives a very uniform fine product and power consumption is low, although it is not suitable for very tough materials and the feed should not exceed about 25 mm in size It is particularly useful with sticky materials which would hold the balls together

## Rod Lengths and Ratios Engine Builder Magazine

Rod ratio is the mathematical relationship between the overall length of the connecting rods and the stroke of the crankshaft Divide rod length by the crank stroke and you get the rod ratio For example, say you’re building a stock small block 350 Chevy with 57inch rods and a 348 inch stroke The rod ratio in this engine would be 57 (rod length) divided by 348 (stroke), which equals 164

This ratio (normally represented by “n”) can be calculated as follows: Ratio “n” = Rod Length ÷ Stroke The rod’s length is measured (for this purpose) from the center of the pistonpin opening to the center of the bigend bore, not overall There is a small range of ratios for most conventional piston engines: the rod is between roughly 14 and 22 times the stroke length It’s not possible for the rod to be the same length

## Length & Diameter to Volume Calculator

Enter the measurements of length and diameter for the object you are calculating, and select the appropriate units for each measurement value entered The following conversion factors in metres (m) are used for converting length and diameter into different units: SI Metric Prefix Length Units yoctometre (ym) – 1 x 1024 m; zeptometre (zm) – 1 x 1021 m; attometre (am) – 1 x 1018 m
