Yixing tianshan cement co., LTD. 2500 t/d production line put into operation in August 2003, adopt LBT32216 grate cooler, grate bed effective area of m2, the first section of the grate bed tilted 3 #176; to decorate, the first row of grate plate grate plate for the activity.
The cooler grate is composed of overlapping rows of perforated grate plates. Half of the rows are static, fixed to the casing of the cooler. The alternate rows are carried on a movable frame to which a reciprocating movement is imparted by an eccentric drive or hydraulic rams.

construction of cement grate cooler. Cement Kilns: Grate Coolers. The essential characteristic of a grate cooler is a layer of clinker spread on a moreorless horizontal perforated grate, through which cold air is blown. The grate is made of steel, and the cold air
The grate cooler adopts a modular construction design, is flexibly adaptable to different scales of the cement kiln. There is no need of conveying equipment for material leakage under the grate bed. The adjustment and optimization of the grate bed help to cool clinker uniformly. High thermal efficiency. High conveying efficiency.
Structure design of the reciprocating grate cooler. The main parts of a grate cooler include the upper shell, the lower shell, multiple grate plates, the grate transmission device, the grate support device, the clinker crusher (breaker), the automatic lubrication device, and multiple cold air fan units.
The grate cooler cooling centrifugal blower fan is applied in cement production line. According to your blower fan parameters, SIMO can make suitable centrifugal fan technical solution for you. If you are interested in centrifugal fan and axial fan, please feel free contact us. Below cement
Clinker cooling is one of the important processes in cement production. Improving the cooling effect is not only beneficial to improve the quality and grindability of clinker, reduce the power consumption of the cement mill, but also can reduce the clinker temperature, recover the waste heat, and create favorable conditions for subsequent cement handling, storage, or transportation.
Grate cooler, as a quench type clinker cooler, is the important cement equipment in the clinker calcination system. Its main function is to cool and transport cement clinker. Meanwhile, provide hot air for cement rotary kiln and precalciner.
Clinker Grate Cooler n a cement plant, grate cooler is a basic machine in the calcining cement system, its main function is to make the ripe cement material to next system. At the same time, the grate cooler could offer rotary kiln and decomposing furnace hot air flow...
The grate cooler is a type of quench cooler. After the cement clinker enters the cooling machine from the rotary kiln, a layer of a certain thickness is laid on the grate plate, and the blasted cold air is passed through the layer moving in the direction perpendicular to each other to quench the clinker.
In cement grate coolers, dense refractory linings backed by insulation materials often results in an unnecessarily heavy construction, which increases fuel expenditure. Furthermore, the lining can be at risk of alkali attacks, which increases maintenance costs.
The thermal efficiency of the grate cooler is 70%75% and the temperature of secondary air is high, so it is a good choice for large scale cement production. The temperature of cooled clinker. Since grate cooler is a type of quench cooler, the clinker can be treated by
operating conditions as in the cement factory of Meft. 2. COOLER DESCRIPTION AND ASSUMPTIONS . The clinker going out of the rotary kiln at a temperature of 1380#176;C is cooled by the air at a temperature of 65#176;C () by a crossflow heat exchange with the top of the highly refractory steel grate. Thanks to an oscillatory movement, the
#0183;#32;The grate cooler is of considerable importance in cement production and its heat distribution plays an important role in evaluating the energy utilization efficiency. In this study, we analyze the heat distribution in the entire grate cooler system of a 5000 t/d cement plant through experiments, and acquire the mass flow rates, inlet temperatures, and outlet temperatures of the cooling air and
Applicable materials: limestone, cement clinker, bauxite, activated lime, aluminum hydroxide, bentonite, etc. Uses: The grate cooler is an important main equipment in the clinker burning system of the cement plant. Its main function is to cool and transport the cement clinker. At the same time, it provides hot air for the rotary kiln and the decomposition furnace, which is the heat recovery of the firing system.
Conventional Grate stCoolers: These are 1 generational grate coolers that have ability to handle large capacities, capable of achieving low clinker temperature, favorable heat recuperation and permits take out of hot tertiary air. Figure gives a typical example of conventional grate cooler. Fig : The Conventional Grate Cooler
As an important process during the cement production, grate cooler plays significance roles on clinker cooling and waste heat recovery. In this paper, we measured experimentally the heat balance of the grate cooler, which provided initial operating parameters for optimization. Then, the grate cooler was simplified into a serinnected heat exchanger network by power flow method.
together with discussion of cement chemistry has been reviewed^by Bogue (1) and Lea (26). These two books are excellent sources of general information on the cement process. Process simulation Grate cooler No published works on the simulation of the grate cooler were found. However, the importance
