Cement production line of a set of equipment is the production of cement production line of cement equipment. Mainly by crushing and homogenization, preparation of raw meal homogenization, preheating decomposition, cement clinker burning and cement grinding packaging process.
 
Process parameters:
In the process of cement production line, each producing one ton of Portland cement grinding at least 3 tons of materials (including all kinds of raw materials, fuel, clinker, gypsum, mixture), according to the statistics, dry process cement production line of grinding operation need to consume power accounted for about 60% of the entire factory power above, of which more than 30% of raw material grinding, grinding coal accounts for about 3%, accounted for about 40% of cement grinding. Therefore, selecting reasonable grinding equipment and technological process, optimization of process parameters, correct operation, cost control system, to ensure product quality, reduce the energy consumption is of great significance.
 
Production methods:
Silicate class representative in cement production technology in the cement production equipment, with limestone and clay as the main raw material, after crushing, raw ingredients, fine grinding is made, and then feeding calcined mature material, in cement kiln and clinker and a moderate amount of gypsum (sometimes mixed with mixed material or admixture) mill.
Cement production equipment with different raw material preparation, can be divided into dry process cement production line (including semi-dry method) and the wet process cement production line (including half wet) two kinds.
(1) dry process cement production process. Raw material drying and grinding at the same time, or first drying after grinding into raw powder feeding dry kiln calcining mature methods of material. But there are also make raw powder, adding suitable amount of water as raw meal ball and mature methods of material into the vertical Bohr stove, called half dry method, is still one kind of dry process production.
(2) the wet process cement production process. After grinding materials and gouache into slurry, wet method kiln calcining mature material feeding method. Also has a wet preparation of slurry dewatering, made from raw blocks into the kiln calcine material, the method of mature called half wet, still wet one kind of production.
The major advantages of the dry process production is low heat consumption, such as dry with a preheater kiln clinker heat consumption of 3140 ~ 3768 kilojoules/kg), the disadvantage is that raw material composition is not uniform, workshop dust big, power consumption is higher. Wet production with simple operation, raw material composition is easy to control, product quality is good, slurry transportation is convenient, less dust workshop, the disadvantage is that the heat consumption of high (clinker heat loss is usually 5234-6490 kilojoules/kg).
 
Equipment included:
Cement equipment including: cement rotary kiln, cyclone preheater, grate cooler is the main equipment of calcining cement clinker, cement rotary kiln has been widely used in cement, metallurgy, chemical industry, etc. The device consists of cylinder, bearing device, belt wheel bearing block device, transmission device, moving kiln head, sealing device, burning device and other parts, the rotary kiln has simple structure, reliable operation, production process easy to control, etc.
Type cyclone preheater is suitable for all kinds of kiln used (see listed in the directory), Shanghai wear walter machinery in the transformation of science and technology, digest the introduction of Japan's kawasaki, nissan 800 tons, nissan 1000 tons of cement clinker on the basis of the main equipment, developed a nissan 500 tons, 2000 tons of calciner with five suspension preheater. Preheater can be widely applied in the medium of cement plant equipment and new reform.
The quench type grate cooler is a cooling machine, its principle is: use met, blow a cold wind over blower to pave on the grate plate into quenching layer of clinker, the collapse of clinker temperature from 1200 ℃ to 1200 ℃, the cooling of a large number of waste gas in addition to the secondary air into the kiln.
