The structure of the grate cooler after the technical transformation is shown in figure 4. the gray part shows the first two sections of the trampoline retained the green part shows the new sinowalk grate cooler after the third section of the trampoline is removed part of the increase is the intermediate roller crusher.

The grate cooler in the cement industry utilize highly powerful fans which adds up to the huge initial capital investment hongyou et al., 2009. in fact, the major role fans play in modern cement operation cannot be overemphasized in the pyro process section most importantly it generates the cooling air for clinker cooling purpose.

Lowering clinker cooler operating costs through new grate plates, compact swing support of the grate, levelradar grate speed control and waste heat recovery article jan 2000.

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 intoeriesconnected heat exchanger.

Grate cooler, asuench 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. there are various types of clinker coolers developed before grate cooler shaft cooler, rotary cooler, etc. compared with them, grate cooler is the.

Grate coolers are used in the nonmetallic mineral industry for the rapid cooling of material previously burned inurnace, such as for example cement clinker or other mineral materials, by cooling such material immediately thereafter on the cooling grate of the grate cooler. along with travelinggrate coolers, devices widely used to convey.

The reasonable control of the grate cooler is the key factor to ensure the heat exchange and cement clinker quality during the clinker cooling process. in this paper, the cement grate cooler pressure of the grate cooler is taken as the research object andement grate cooler pressure prediction model is proposed based on the analysis of the current status of.

The design of the cooler grate for the sf crossbar cooler and for the multimovable crossbar cooler is in two parts and shaped likeave. this means that the airflow is only deflected by 135 degrees, making it move inave pattern and reducing the internal flow resistance and thereby lowering the pressure drop.

A grate cooler of simple construction whose cooling grate is substantly protected against wear and which can be operated in simple fashion and withigh cooling efficiency.lurality of rotatably supported tubular oscillating shafts, spaced apart from one another, are arranged transversely to the conveyance direction of cooling feed material abovetationary cooling.

Being an iso 90012000 certified firm in the industry, our adept technocrats manufacture these grate coolers using qualitytested raw materials and pioneering techniques. widely demanded in cement, sugar and other allied industries, the provided coolers are used for cooling the clinker in hassle free manner.

A 5000td new dry cement clinker production line ofompany uses the third generation drive grate cooler, which is divided into three stages to drive grate bed by hydraulic pressure. in the pastears since the grate cooler was put into operation, there have been several hydraulic failures. although each failure was finally dealt with after analysis, it was.

Grate coolers. stationery grate coolers. early systems used rotary coolers, which were rotating cylinders similar to the kiln, into which the hot clinker dropped.the combustion air was drawn up through the coolers as the clinker moved down, cascading through the air stream. in the 1920s, satellite coolers became common and remained in use until.

Cooler is mainly composed of cylinder, transmission device, cooling device, sealing device and supporting roller device. hightemperature 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.
