The final step is finish grinding. The Monarch finish milling system consists of five ball mills—large rotating cylinders containing steel balls. As the feed enters the mill, the balls continuously crush and grind the clinker and gypsum into a fine powder, a process known as comminution.

"clinker" which is round, marble-sized, glass-hard balls which are harder than the quarried rock . The clinker is then fed into a cooler where it is cooled for storage . Finish Grinding. The cooled clinker is mixed with a small amount of gypsum, which will help regulate the setting time when the cement is

Cement production is similar all over the world. Raw material such as limestone, clay and sand and other aggregates are mined in quarries. They are ground and milled. The raw mix is fired in a rotary furnace at approx. 1,450 degrees Celsius to make clinker brick. In another mill, gypsum is added to form the end product - cement.

In cement production, the clinker burning process with the cyclone preheater, the kiln and the clinker cooler, is the heart of the process. The design and the process technology selected along with the relevant process automation have an important influence in cement quality. The speed of cooling influences the clinker properties considerably:

Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

Clinker grinding aids. Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall.

The cost savings from replacing clinker with additives (see Item 1 above) are likely to be the largest. While production costs are plant-specific, a plant producing one million tons of cement per year will produce less clinker equivalent to the amount of finish mill additives added, i.e. 5% clinker saving in this case or 50,000 tons per year.

In these coolers, the clinker is cooled from about 1100°C to 93°C (2000°F to 200°F) by ambient air that passes through the clinker and into the rotary kiln for use as combustion air. F. Finish Grinding: The clinker tumbles onto a grate cooled by forced air. Once cooled, the clinker is ready to be ground
