Step 5: Cement grinding After mixing with gypsum and admixtures, the clinker is sent to a cement mill for grinding. Cement grinding can be carried out either in an integrated cement plant or in a standalone cement grinding station. 3. What should limestone be mixed with to make cement? This needs to start with the cement composition.

1. Introduction. Cement grinding is a key process in the cement industry. During this phase, gypsum and mineral or artificial raw materials (eg pozzolan, ash, limestone) are added to the clinker (basic raw material for cement production) and, then grinded in special mills until a very small grain size is achieved.

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

Module 4: Cement Grinding Systems and Dispatch. Cement clinker is grinding in roller mills and ball mills, such as granulated blast furnace slag, fly ash, limestone, and approximately 5% sulfate agents (, gypsum). During production and before leaving the plant, the cement is internally inspected and tested in the plant's laboratories.

At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills.

Cement milling is the process of grinding together cement clinker, gypsum and other additives to produce a fine grey powder. The resulting material, called "cement meal", is then heated in a rotary kiln to around 2,000°F to produce the finished product known as Portland cement, which can be used for many different construction purposes.

Then the fly ash will be fed into powder concentrator for the first classifying. During the classifying, qualified fine ash enters the fine ash silo through conveying chute, while the coarse ash is sent to the cement ball mill for fine grinding. After grinding, the pulverized fly ash needs to be classified again in the powder concentrator.
