Portland cement clinker is made by heating in a rotary kiln at high temperature a homogeneous mixture of raw materials. The products of the chemical reaction aggregate together as molten minerals at the sintering temperature. The sintering temperature for modern cements is about 1450 °C. Aluminium oxide and iron oxide are present as a flux and contribute little to the cement strength. For special cements, such as Low Heat (LH) and Sulfate Resistant (SR) types, it is necessary to limit the amount of tricalciumaluminate (3 CaO·Al2O3) formed.
cement ball mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills. To use the Ball Mill, the material to be ground is loaded into the Neoprene barrel that contains grinding media. As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours. Obviously, the longer the Ball Mill runs, the smaller the powder will be. Ultimate particle size depends entirely on how hard the ground material is, and how long the Ball Mill runs. Our Ball Mills have been being used to grind glass, make ceramic glaze, powder various chemicals, and make Black Powder.
