Let's show you the general cement production process plant which is as follows:
1. The cement manufacturing process begins when limestone, the basic raw material used to make cement, is transported by rail to the cement production process plant from the limestone quarry site.
2. The limestone is combined with clay, ground in a limestone crusher and fed into the additive silos. Sand, iron and bottom ash are then combined with the limestone and clay in a carefully controlled mixture which is ground into a fine powder in a 2000 hp roller mill.
3. Next, the fine powder is heated as it passes through the Pre-Heater Tower into a large kiln, which is over half the length of a football field and 4.2 metres in diameter. In the kiln, the powder is heated to 1500 degrees Celsius. This creates a new product, called clinker, which resembles pellets about the size of marbles.
4. The clinker is combined with small amounts of gypsum and limestone and finely ground in a finishing mill. The clinker grinding mill is a large revolving cylinder containing 250 tonnes of steel balls that is driven by a 4000 hp motor. The finished cement is ground so fine that it can pass through a sieve that will hold water.
5. The cement manufacturing process consists of many simultaneous and continuous operations using some of the largest moving machinery in manufacturing. Over 5000 sensors and 50 computers allow the entire operation to be controlled by a single operator from a central control room.
As a leading cement plant manufacturer, they plan all designing, construction & other outfits circumstances according to the location after proper inspection where the plant needs to be installed. Once all the designing & planning work approved the system will start with the limestone this is the basic raw material used for making cement. Limestone is combined with clay, ground in crusher & than fed in the additive silos. Iron, Sand & bottom ash combined with limestone & clay (specific ratio is important) than ground in to fine power in roller mill.
Than fine powder heated as it passes through the pre heater town in to a giant kiln, in the kiln the powder heated to approx 1500 degree Celsius it will generate new product which called clinker.
Clinker is combined with gypsum & limestone & finely ground in finishing mill. Mill is giant revolving cylinder its need approx 4000HP motor to revolve the cylinder.
Cement manufacturing system plenty of simultaneous & continuous system.
