What are the differences between the wet and dry processes the wet process of cement manufacturing involves adding water to finely crushed raw material such as limestone clay or iron ore in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln whereas no water is added in the dry process

The terms curing and drying are frequently used interchangeably with regard to the moisture condition of new concrete slabs the following definitions clarify these terms curing of concrete is defined as providing adequate moisture temperature and time to allow the concrete to achieve the desired properties for its intended use

Dry mix process and wet mix process are the two methods of shotcrete construction which are based on the time at which the water is added to the mortar or shotcrete is a type of concrete or mortar mix that is shot onto a surface at highspeed the shotcrete process can be performed in two ways either using a dry mix or by means of a wet mix
The procedures of the wet process are basically the same with the dry process which can be divided into three stages raw materials preparation clinker calcination and the cement grinding all of these stages are covered in the article what you need to know about portland cement manufacturing process we mentioned before

The dry process consumes much less fuel as the materials are already in a dry state whereas in the wet process the slurry contains about 35 to 50 percent water in a recent trend the majority of cement factories are using the dry process of cement manufacturing
Whereas the dry cement process consumes 360975 mj ton the high energy consumption of the wet process over the dry can be attributed to the mix preparation method adopted prior to burning of clinker in the kiln water being added to the raw materials to form raw thick slurry whereas the dry process is only based on the preparation of fine powdered raw meal by grinding raw material followed
