subject: Cement Mill Used In Cement Production Line [print this page] In the cement production line, cement mill is used to grind cement ingredients into powder for cement making.
In the cement plant, cement mill is used to grind crushed limestone, coal, gypsum, cement clinker into powder.
Limestone grinding mill is common cement mill used for grinding limestones into powder. Raymond mill for limestone grinding plant: Raymond mill is the most common grinding machine used in stone grinding plant. The fineness can be upto 200 mesh.
Ball mill for limestone powder production line: Ball mill is the early grinding machine used in stone powder production line.
Gypsum mill is also widely used cement mill in cement industry. The gypsum grinding mill machine has the advantages of compact size, simple structure, high productivity, low energy consumption, stable physical performance, ease of operation and low operating cost. Today, our gypsum powder production line is well received in USA, Canada, France, Germany, England, Spain, Iran, Pakistan, Thailand, Australia, Thailand, Uzbekistan, Colombia, Mexico, etc.
Coal pulverizer is the common cement mill used in cement factory. Coal ball pulverizer is an efficient tool for grinding many materials into fine powder. The Coal ball pulverizer is used to grind many kinds of mine and other materials, or to select the mine, widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
The cement manufacturing process begins when limestone, the basic raw material used to make cement.
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 ground into a fine powder in a 2000 hp roller 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 a 4000 hp 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.
