Cement Kilns Wet and semi-wet process kilns

The high fuel requirement of wet process kilns means that the kiln must handle a large amount of combustion air a mass-flow typically 2-3 times the clinker output and handling this amount of gases places a limit on the output of wet kilns.

Energy Source for Cement Kilns KIS Knowledge is Power

Jan 10, 2008 · Cement production is very energy intensive involving both heat (clinker production) and electricity (grinding of feed and clinker). The most modern plants in operation today which use the dry process and have pre-calcination and pre-heaters consume around 80 kwh of electricity per tonne of clinker and 600 kcals of heat for each kg of clinker produced.

Jan 29, 2016 · Cement manufacturing process. The slurry is put in a storage tank with a capacity of several hundred tons, mixed to be homogenized with the corrective materials, and is sent to a rotary kiln for clinker burning. In the wet process, the slurry can be easily mixed but a large amount of energy is consumed in clinker burning due to water evaporation.

process. The clinker for each one of these processes has particular characteristics that differentiate it from production methods and specific heat consumption; data in Table 1 correspond to clinkers for producing grey cement. For white cement the specific consumption is between 1800 and 2200 kcal/kg of clinker with the wet method.

The difference between wet process and dry process

The wet process suffered the obvious disadvantage that, when the slurry was introduced into the kiln, a large amount of extra fuel was used in evaporating the water. Furthermore, a larger kiln was needed for a given clinker output, because much of the kiln's length was used up for the drying process.

Cement Industry Overview

Since 1974, the number of wet process kilns has dropped from 234 to 25- a decline of 89 percent- while the number of dry process kilns has only been reduced from 198 to 124. Well over three quarters of existing U.S. clinker production capacity has been built since 1975- all utilizing the dry manufacturing process.
