LS series third generation improved stoker-type grate cooler
Specifications series and description

From the early 1990s, through the foreign-driven Grate cooler technology, equipment introduction and assimilation, as well as continuing their own research, optimization and improvement of domestic professional institutes, development and design of a distinctive Grate cooler products. Grate cooler joint exploration company engaged in the design and development of personnel from these institutions are senior professional engineer.

Products to be doing fine doing fine must be grabbed from basic research, in recent years we are about cooler of clinker processing, Grate cooler cooling efficiency, reliability and other aspects of the system analysis through model experiments, field calibration and theoretical calculations analyzes the different temperature zones, different types of grate plate cooling effect difference in the rational allocation of cooling air and reduce line losses and improve the grate plate life and operational reliability, increased resistance to abnormal (as a result of raw materials, fluctuations or fan operation, etc. failure caused by the running yellow material, knot chunks, presses, etc.) capabilities, so that products are not only useful, but also durable, worry, low maintenance workload.

We have been put into use by summing the hundreds of different specifications Grate cooler usage, through the cooling heat exchange mechanism studies to optimize the fixed bed and the high temperature zone inlet grate bed with the wind, improving the grate plate permeability, improved mechanical structure of the new design, superior performance dedicated LS series stoker-type grate cooler.

Technological, structural features:

1) improved entrance fixed bed system, plus the optional forms of air guns or hydraulic pusher solutions, not only quench clinker good effect, and can avoid the "snowman" phenomenon.

2) different units and different regions grate plate configured and controlled refinement for the wind, so that the cooling air is distributed more evenly and effectively eliminate the "Red River" phenomenon.

3) high cooling efficiency, the clinker temperature is low, the quality is good, the clinker and the adaptability of firing conditions (including the end grain, yield, etc.) strong.

4) heat recovery effect, and stable at high temperature to provide a secondary, tertiary air, based on the heat may need to provide reliable power generation and the drying air into the decomposing kiln at the ouside of kiln exhaust gas temperature of the dust collector is low.

5) well-designed large stiffness of the structure, so that uniform gap grate bed, anti unusual circumstances (such as the collapse of the decomposing kiln at the ouside of kiln leather, knot large eggs, etc.) greatly enhanced ability to avoid the press and other phenomena.

6) critical, important pieces of high quality and large quantity of rich selection or design, greatly improve the reliability of the equipment.

7) Special structure type anti-wear grate plate, grate flow line labyrinth joints, not only uniformity of the wind, air permeability, and the entire grate drain less material, less wear and long life.

8) user-based humane ideas to make device operation, inspection and maintenance is simple and convenient, and low cost.

9) running high, will not occur due to cooler problems affecting production.

● LS series fourth generation cooler

Specifications series and description

In recent years, the world has witnessed a new concept of a new generation cooler, such as FLSmidth's Cross-bar, CP of η, KHD's PYROFLOOR, Polysius the PolyTRACK so on. They all have a modular, no leakage, wear parts and less in common. But in the cold grate bed allocation and delivery of materials the way, they are not identical. Cold air distribution: Smith, KHD other uses automatic air flow control valves, and other companies are using CP refine plenum air distribution methods, no regulator.Material handling aspects: CP, KHD, etc. using stepping out grate bed, while the other is used Polysius and Smith fixed grate bed through pusher pusher rod or block delivery of materials to achieve the purpose. These fourth generation cooler, although currently in use in small quantities, but I believe that in the near future, with the function and structure of continuous improvement, will gradually replace third generation cooler and become the mainstream market.

The company has been focused on international Grate cooler on the latest research, since its inception, it begin developing fourth generation cooler. After years of full investigation, in theory, structure and use of effects and other aspects of different forms of fourth generation cooler at home and abroad is analyzed and compared on the basis of improvements, optimization and improvement of the formation has its own characteristics of fourth generation cooler design ideas. Its programs carefully, advanced technology, product reliability.As a result of standardized design, through different combinations of the number of standard modules, products of different sizes to cover the current production line needs.

LS series fourth generation cooler technology, structural features:

1) Modular design, according to the need to facilitate the composition of different sizes cooler, manufacture of high precision, short cycle, easy installation and maintenance.

2) using column-grate, grate plate each column independently governor, for the distribution of clinker has good adaptability.

3) The use of automatic flow control valve and a more refined partition for the wind to prevent cooling air circuit, ensuring stable air distribution.

4) Standard grate clinker layer board is still covered to protect it from heat and wear, grate plate no longer require periodic replacement.

5) special type no leakage grate plates and non-contact seals to ensure that no leakage of material, eliminating the need hopper and conveyor systems.

6) Activities grate bed perfectly level, coupled with ash bucket, so that the whole height greatly reduced, significant savings in construction investment.

7) between each column grate plate special sealing structure, seals adjustments easy assembly and disassembly, no empty grate plate stationary material layer, and easy maintenance.

Therefore, the new Grate cooler with mounting short manufacturing cycle, clinker cooling effect, heat recovery efficiency, less investment, less wear parts, production and maintenance and low cost.
