Cement Kilns: Design features of rotary kilns

Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C, while the gas temperatures reach 1900°C.

Pile Integrity Tester (PIT) Pile Length and Diameter ...

The maximum length/diameter ratio depends on pile uniformity, soil strength, and the actual length and diameter measurements. Under good conditions, the L/D ratio may exceed 30 — even reaching 60. For more information click here. Nevertheless, a drilled pile does not guarantee that the cross section will have an uniform length.

Compressive Strength Test on Concrete Core

Measurement of Concrete Core. Before testing, measure the length of the capped or ground specimen to the nearest inch [2 mm] and compute this to calculate the length diameter [L/D] ratio. Determine the average diameter by averaging the two measurements taken at right angles to each other at the mid height of the specimen.

Ball Mills

Optimum ratio between length L and diameter D, L:D is, usually, accepted in the range – The mill productivity also depends on many other factors: physicalchemical properties of feed material, filling of the mill by balls and their sizes, armor surface shape, speed of rotation, milling fineness and timely moving off of ground product.
