grate cooler in cement plant

The clinker progresses through the cooler by moving along the grate, and so the direction of the cooling air is at right angles to the direction of the clinker’s movement. The grate cooler

The main purpose of cement rotary cooler: Reduce the temperature of the clinker as low as possible for subsequent grinding, transportation, and storage. Recycle the heat energy from the clinker as much as possible to heat the secondary and tertiary air, making them combustion air and minimizing the fuel consumption of the cement rotary kiln system.

In cement industries, grate coolers are commonly used for heat recovery from For this analysis, a cement plant's grate clinNer cooler, 

Production Capacity: 2-36t/h. Specification: φ 1.5x15m- 3.3x40m. Application: cement, silicate products, new building materials, refractories, glass, ceramics and other industries. Get

According to the movement of grate, grate coolers can be divided into rotary type, vibrating type, and reciprocating grate type. Output of per unit grate area： 50t/m2·d. Thermal efficiency： 70%-75%. Heat consumption can be reduced： 100kJ/kg·cl. Pros The discharged clinker has uniform particle size and low temperature.

7/10 · World Cement , Friday, 10 July 09:15. Advertisement. Valentina Bordei, thyssenkrupp, discusses the optimisation of clinker coolers to meet industry demands for energy efficiency and low maintenance. In every cement plant, the cooler operation has a crucial impact on operating performance, clinker quality and overall productivity.

The grate cooler is the main equipment in calcining system of the cement plant. Its main function is to cool and transport the cement clinker. It also provides hot air for rotary kiln and decomposing furnace, and it is the main equipment for heat recovery in calcining system. Grate cooler of CHAENG is new energy-saving clinker cooling equipment

The grate cooler belongs to the family of air quench cooler (AQC). The clinker fed into the grate cooler can be quenched from 1300-1400 ℃ to below 100 ℃ in just a few minutes. The grate

Cooler is mainly composed of cylinder, transmission device, cooling device, sealing device and supporting roller device. High-temperature clinker enters into the cooling machine through feeding device, and the cooling machine rotates and drives the material to roll forward for full heat exchange with air. The material is cooled below the rated temperature after passing through rotary cylinder

A modern 4½ x 70-ft Air-Quenching grate cooler in a US cement plant. A cooler this size will cool clinker at a rate of 100 barrels per hour. Clinker Grinding Costs Rapid Air-Quenching — Clinker from an Allis- Chalmers grate cooler is a true air-quenched clinker, having favorable grinding characteristics.
