Jul 02, 2008 Re: CLINKER FROM ROTARY OR VERTICAL SHAFT KILN. There are a number of reasons why the clinkers might differ, but buying clinker from a VSK would not be a completely wrong move. It would depend on the degree of combination of the clinker, the lime saturation and the silica modulus. There are at least 2 principle reasopns why the clinker from a ...

Now cement kilns can be divided mainly into 2 types: vertical shaft kiln and rotary kiln. The vertical kiln is the older type and its origin dates back to the 5th century AC. Rotary kilns were first used in 1880. Around the 20th century, they replaced vertical shaft kilns almost everywhere. 3. The Importance Of Cement Kilns A cement kiln is a ...

Although the energy consumed per ton of cement has declined markedly in the past ten years, the industry still uses more than three and a half times the fuel that is theoretically required to produce a ton of clinker. Improving kiln thermal efficiency offers the greatest opportunity for saving fuel.

Dec 17, 2020 The heart of the clinker production process is the kiln, which can be rotary or vertical shaft designs. Rotary kilns are commonly used in the U.S. and elsewhere. Fig. 8.2 A schematic of the cement manufacturing process. These kilns are 6-8 m in diameter and 60 m to well over 100 m long. They are set at a slight incline and rotate at 1-3 rpm.
