The process of cement manufacturing should be known well by the investor planning to set up the cement plant. The basic process of cement manufacturing include the raw material preparing, crushing, preheating, calcination, grinding and package.

First, the main raw materials used in the cement manufacturing process are limestone, sand, shale, clay, and iron ore. The limestone is combined with clay, ground in a 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 groundinto a fine powder in aroller mill.

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 meters 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.

The clinker is combined with small amounts of gypsum and limestone and finely ground in a finishing mill. The mill is a large revolving cylinder containing 250 tonnes of steel balls that is driven by motor. The finished cement is ground so fine that it can pass through a sieve that will hold water.

The cement manufacturing process consists of many simultaneous and continuous operations using some of the largest moving machinery in manufacturing.

We provide the full range service including design, manufacturing, and installation. We design and manufacture devices for new type dry method cement production line, for which the capacity varies from 50tpd to 3000tpd.
