Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.
Cement rotary kiln is the main equipment of calcining the cement clinker. The characteristics of a rotary kiln are simple structure, convenient and reliable control of the producing process.
An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar materials.
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
The combination crusher is a new generation high efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas.
Chute feeder is a kind of feeding equipment which is earlier used in storage trough and it is suitable for the short-distance transport of metallic and non-metallic materials.
In its simplest form,concreteis a mixture of paste and aggregates, or rocks. The paste, composed of portlandcementand water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known asconcrete.

Functions ofcement ingredients. Theingredientsof ordinarycement, as mentioned above, perform the following functions: Lime (CaO): This is the important ingredient ofcementand its proportion is to be carefully maintained. The lime in excess makes thecementunsound and causes thecementto expand and disintegrate.
