Wet process kilns. The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated and the process of heat

Alternative fuels co-processing in cement production
Co-processing in cement production operations refers to the use of alternative fuels in both combustion and production processes. In terms of combustion, it involves substituting primary fuels, such as coal, petroleum and gas, with waste. This typically consists of combustible municipal waste or refuse-derived fuels (RDF), biomass, and non-hazardous industrial and
A Review On Environmental and Health Impacts Of Cement
wet process, or the semidry process [10]. In a dry cement manufacturing process, dry raw mix contains less than 20% moisture by mass. However, in a wet process water is added to the raw mix to form slurry and then is transported to the kiln [11]. Raw meal or blended raw materials are fed into the upper end of the pre-heater tower and then passed through the end of the rotary
The Cement Manufacturing Process Advancing Mining
Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the stone bonds of the raw materials are broken down and then they are recombined into new
