Cement Production Line For Sale In Kenya
Cement is really a fine grey powder that when they are reacted with water hardens to make a rigid chemical mineral structure which usually offers concrete its high strengths. A cement production plant consists of the following three processes: raw material process, clinker burning process, finish grinding process. The raw material process and the clinker burning process are each classified into the wet process and the dry process.
Wet process of cement production
In the wet process, raw materials other than plaster are crushed to a diameter of approximately 20 mm by a crusher and mixed in an appropriate ratio using an automatic weigher. Then, with water added thereto, the mixture is further made finer by a combined tube mill with a diameter of 2 to 3.5 m and a length of 10 to 14 m into slurry with a water content of 35 to 40%. 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.
Dry process of cement production
In the dry process, crushed raw materials are dried in a cylindrical rotary drier having a diameter of 2 m and a length of about 20 m for example, mixed by an automatic weigher, ground and placed in storage tanks. The resultant mixture is further mixed to make the ingredients uniform, and sent to a rotary kiln for clinker burning.
