PDF Application Fact Sheet - French Cement Ball Mill
A cement plant in the south of France is dependent on continuous ball mill operation for powdered limestone production. Shutdown for inspection or maintenance creates lengthy and costly non-productive periods. Lubricant retention problems caused by the slow speed and high operating temperature also created shutdown periods for
Curing Concrete – Normal, Hot and Cold Weather
For most concrete structures, the curing period at temperatures above 5º C (40º F) should be a minimum of 7 days or until 70% of the specified compressive or flexural strength is attained. The period can be reduced to 3 days if high early strength concrete is used and the temperature is above 10º C (50º F).
Types of Cement and their Uses (12 Types) – Civilology
Types of cement. Cement is a binding material used to bind different type of construction materials together. It is formed from argillaceous, siliceous, calcareous etc. By twisting this internal mix ratio and by altering the chemical inputs, special types of cement can be produced according to the needs.

Stage 4: Finish Process | Cement Production
Obtaining the optimum amount of rapidly-soluble sulfate requires milling with a mill exit temperature within a few degrees of 115°C. Where the milling system is too hot, some manufacturers use 2.5% gypsum and the remaining calcium sulfate as natural α-anhydrite (CaSO 4). Complete dehydration of this mixture yields the optimum 2% γ-anhydrite.
