Cement mill

 Introduction:
This equipment can be used to grind the hard, nodular clinker from the cement kiln into the fine grey powder.

In order to achieve the desired setting qualities in the finished product, a quantity of calcium sulfates (usually gypsum or anhydrite) are added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement mill. The grinding process is controlled to obtain a powder with a broad particle size range. The measure of fineness usually used is the specific surface area, which is the total particle surface area of a unit mass of cements. The cement is conveyed by belt or powder pump to a silo for storage. Cement plants normally have sufficient silo space for 1–20 weeks production, depending upon local demand cycles. The cement is delivered to end-users either in bags or as bulk powder blown from a pressure vehicle into the customer's silo. In industrial countries, 80% or more of cement is delivered in bulk.
