Process and Equipment of the Cement Production Line

The focus of this article- cement production line refers to the production line which composed of a series of devices. It is mainly constituted by crushing and pre-homogenizing, raw material preparation homogenizing, preheat decomposition, the firing of cement clinker, cement grinding packaging,and the other processes.

Cement production line producing method

The representative process in cement production equipment is the silicate cement production process , in this process, the limestone and clay are main raw materials, after the crushing, ingredients, finely ground, we can obtain the raw materials, and then fed to the cement kilns burning mature, cooked material plus the amount of gypsum (sometimes mixing the mixed material or admixture) ,finally ,we can get the cement.
according to the raw material preparation ,
cement production equipment methods can be divided into dry process cement
production lines (including semi-dry) and wet cement production line (including
the semi-wet) these two kinds.
① dry-process cement production process.
drying and grinding raw materials together, or first dried by grinding the raw
material powder feeding dry kiln burning mature. But people also the raw
material powder ball made of raw material, adding an appropriate amount of water
fed into the kiln burning mature Lepol method, called semi-dry, it is still a
kind of dry method production.
② wet cement production process. Raw and
gouache ground raw slurry feeding wet kiln burning mature. Wet preparation of
raw slurry dewatering, made of raw materials after the block into the kiln
burning mature method, called semi-wet, still wet production a.
The main
advantages of the dry production are: low heat consumption (dry process kiln
with preheater heat consumption of clinker for 3140 to 3768 kJ / kg), the
disadvantages are not easy even raw ingredients, shop dust, power consumption
higher . Wet production has the advantages of simple operation, easy control of
raw ingredients, good product quality, convenient slurry transport, small shop
dust, high heat consumption (heat consumption of clinker is usually 5234 to 6490
kJ / kg).

Cement production line contains the following devices: cement rotary
kiln, the whirlwind preheater, grate cooler
Cement rotary kiln is the
main equipment for calcining cement clinker ,which has been widely used in
cement, metallurgy, chemical and other industries. The equipment consists of the
cylinder, the supporting device, with a gear wheel bearing device,
transmissions, activity Yaotou, kiln end sealing device, combustion devices,
components, having the features of simple structure, reliable operation, easy
production process control .
