1). Freezes of the clinker liquid phase as the clinker passes through the first cooling zone in the rotary kiln or on falling down the chute into the grate cooler. The clinker dust particles carried back by the secondary air stream from the clinker bed grate into the interior of the rotary kiln also play an important role on formation snowmen.

Clinker Cooler. The hot clinker produced by the rotary kiln is transferred to a grate cooler, where it is cooled by air blowers before being taken by conveyor belt to the cement mill. It is essential to monitor the clinker for rogue hot inclusions before it reaches the belt and causes damage. Any rogue hot inclusions in the cooled clinker could ...

It must need extremely cold treatment. get a quote learn more Table Of Contents…

The clinker cooler is an important part of the cement manufacturing process, as it plays a crucial role in controlling the temperature of the clinker leaving the kiln.

Clinker cooling process. A very important process during cement production is the cooling of the clinker, since to a large extent the quality and characteristics of the cement depend on this phase. The hot clinker produced in the rotary kiln is transferred to a cooler, where it is cooled by air blowers before being conveyed to the cement mill.

Energy recovery and exergy recovery in a clinker cooler was a major factor in optimizing clinker production and cement grinding process, the running clinker cooler has an energy recovery was 48.31 ...

The grate cooler is a type of clinker cooler, it plays an important role in the clinker manufacturing process. The grate cooler in a cement plant cools and transports the cement clinker from the rotary kiln, and provides heating air (secondary air) for the rotary kiln and preheater. The performance of the grate cooler will directly affect the ...

The rotary cooler produced by AGICO has the advantage of simple structure, high heat efficiency, low maintenance cost, less total investment, etc., which are often used to cool the clinker of 500 ~ 2000t/d cement production lines. Besides, we also offer conveying equipment, feeding equipment, and other related cement equipment according to ...

While, at a specific number of 1.7959 Nm 3 /kg clk and at a clinker bed height of 0.3 m, the lowest recoverable efficiency of 57.52% was recovered into the modelled clinker cooler and with highest outlet clinker temperature of 168.7 °C. Hence, specific number of airs to clinker also plays a significant role in clinker cooler performance.

Cooler. Clinker cooler serves two main objective of cooling clinker from temperature of about 1350 0C to the temperature (65-150 0C) where it can be handled by conveyors like pan conveyors, chain, Elevators etc. and …

The clinker production stage is where the raw material (the raw meal) converts into clinker. The raw meal is fed into a rotary kiln through a preheater at about 1450 °C to produce clinker, the primary cement component (GHG, 2008; Salas et al., 2016 ). The kiln is known as the heart of the cement production process.

Clinker Grate Cooler. Processing capacity: 800-4000t/d. Applications: Cement, silicate products, new building materials, refractory materials, glass ceramics and other production industries. Applicable materials: limestone, cement clinker, bauxite, activated lime, aluminum hydroxide, bentonite, etc. Uses: The grate cooler is an important main ...

Cooling clinker is a serious job. It's a vital step in ensuring the final quality of the clinker and enhancing overall process efficiency by recuperating heat to the kiln. It's therefore critical that your clinker cooler operates reliably and efficiently at all times. Which is the job of the cooler hydraulics – and our cooler hydraulic control systems: PFC-HC for …

The key is to maximise waste heat recovery, while maintaining high recuperation efficiency. Seeking greater productivity. Coolers are often the cause of operational bottlenecks. Reduced recuperation efficiency, increased vent losses, high clinker temperature and insufficient heat input to the WHRS boiler are just a few.

The reciprocating grate cooler is the mainstream clinker cooling equipment in most cement plants today. Advantages of 5th generation grate cooler: 1.Height reduction by 2-3 meters 2.Grate plates free of abrasion 3.No leakage beneath grate plates 4.Progressive flow control valves 5.Unique support structure 6.Unique conveying method 7.Inlet fixed ...

The so-called snowman in the grate cooler is a name get from the image itself. In fact, it means the clinker accumulates under the rotary kiln before go through into cooler which become higher like a snowman. In severe cases, it can be blocked at the kiln outlet and the clinker can not move out. The main causes of snowman: 1.

Grate Cooler. 1. Introduction. Clinker Cooling is an Important phase in clinker production. Clinker Cooler is exposed to extremely difficult operating-conditions with a highly abrasive and hot material. The Cooling Rate of clinker at elevated temp. has direct impact on cement strength (fig.1). cooling and grindability of clinker.

The essential function of grate coolers is a waste heat recovery from hot clinker which leaves the rotary kiln. This paper presents an analysis of energy and exergy based on the clinker temperature profile. It focuses on the distributions of temperature, energy and exergy for cooling air and hot clinker along the grate cooler in cement …

The coolers in practice were almost useless. Masons, using them up to the 1960s, recorded clinker outlet temperature around 1000°C, and the "quenching" of the clinker, necessary for good quality, was delayed until it fell out onto the conveyor.. A modest improvement in performance could be obtained by fitting a "van der Werp" cooler. This …

As a standard continuous system, the clinker calcination process can be divided into preheating decomposition link, rotary kiln firing link and grate cooler cooling link. The links are coupled with each other, and there is a competitive relationship between multiple optimization target parameters. For get the optimal value setting of those parameters, it …

2.1.1.1 Portland cement clinker (K) The definition given in ENV 197–1 4 is as follows: Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates ( (CaO)3 ·SiO 2 and (CaO) 2 ·SiO 2 ), the remainder containing aluminium oxide (Al 2 O 3 ), iron oxide (Fe 2 O 3) and other oxides.

The simplest way to cut your clinker cooling costs with the Cross-Bar® Cooler. The first Cross-Bar® Cooler was installed in 2009 – still early days for the FL team working on the development, but little did they know that the new design would dominate the market in the following decade. When cement equipment delivers on its promise to ...

In fact to transform the raw meal into clinker, the temperature needs to be as high as 1450°C (2642°F). As the name implies, the clinker cooler lowers the temperature and carries the clinker from the kiln. It also provides heated air for the rotary kiln and the preheater. The clinker is cooled to a temperature of about 150°C (302°F).
