Old Stuff from the Oil Fields - Drilling Equipment
Though it took time, rotary drilling slowly made slow inroads in the oil patch, and today virtually all wells are drilled with rotary power. A picture of a drill crew on an early rotary rig at Coalinga field in 1917 is shown below. They are standing in front of the "kelly bushing", which is a device that clamps around the "drill pipe" and ...

Manufacture of Portland Cement- Materials and Process
The rotary kiln is made up of steel tubes having the diameter of 2.5-3.0 meter and the length differs from 90-120meter. The inner side of the kiln is lined with refractory bricks. The kiln is supported on the columns of masonry or concrete and rested on roller bearing in slightly inclined position at the gradient of 1 in 25 to 1 in 30.

Cement: The Thomas A. Edison Papers at Rutgers University
From 1898 to 1902, he developed new cement-processing technologies, including a giant rotary kiln, which eventually allowed the Edison company to increase production and realize cost-savings. The cement company did not become a profitable enterprise until 1922, the year construction began on the stadium.

History of cement
It is interesting to note that the Navarros, who first successfully used a continuous rotary kiln for portland cement, had in 1886 operated a batch-process rotary furnace for burning "natural" cement. It was 24' × 12', "similar to a large peanut roaster". From the 1870s onward, a number of patents were filed for rotary kiln processes in Britain.

The cement kiln
Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...
