Too much clinker plus 25 mm increases the clinker temperature after the cooler because of the too slow cooling of this fraction. Less than 10% plus 25 mm is good. The clinker dust in the cooler tends to blow back into the kiln, thus establishing a dust circulation between kiln and cooler.

If snowmen forms in the cooler inlet, they have to be removed manually – which can mean significant downtime. The Cross-Bar Cooler's ABC Cooler Inlet blasts air directly to the grates and clinker bed, where traditional blaster can't reach. This eliminates snowmen and prevents dead-zones, meaning no more snowmen-enforced downtime.
In every cement plant, the cooler operation has a crucial impact on operating performance, clinker quality and overall productivity. The development of clinker coolers in recent times has been guided by market demands for maximised availability, reduced maintenance and rapid conversion with minimum production downtime, accompanied by …
What Is Clinker Cooler? In the calcination process of cement clinker, preheating, calcining, and cooling are three inseparable process links. As the supporting equipment of a cement rotary kiln, a clinker cooler (also called cement cooler) is a kind of heat exchange device that transfers heat from high-temperature clinker to low-temperature gas.It plays …
(2) For open clinker storage piles, the operations and maintenance plan must specify that one or more of the following control measures will be used to minimize to the greatest extent practicable fugitive dust from open clinker storage piles: Locating the source inside a partial enclosure, installing and operating a water spray or fogging ...
At each clinker fines discharge outlet air is blown into the cooler at the required volume to bring down the temperature. The air flow volume is individually adjusted to optimize the clinker cooling process. Uncontrolled build-up of clinker fines in the discharge outlets will considerably affect this cooling air flow and cause mechanical
Cooler conditions influence the burning process in the kiln and consequently, the quality of the clinker. There are many instances where cooler operating problems can lead a perfectly stable kiln into a severely upset condition with possible …
Grate Cooler 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).
In the late 1990s, a new type of clinker cooler was introduced. It shares the horizontal conveying of clinker through which a vertically moving mass of cooling air is blown with …
Clinker cooler. The hot solids from the kiln are discharged on the grate of clinker cooler. As the grate moves with uniform speed along the cooler length, solids lose their heat to cross-flow air. A part of the air is generally sent to the kiln as secondary air, a part to calciner as tertiary air and a part is vented to the surroundings (vent air).
Specific alloys are available for different areas inside the cooler. Its patented bar and clinker pocket grates are designed to fit with the existing supports with no change needed to the fans or structure. ... There is an optional service of specialized supervisors who can ensure perfect alignment of the cooler grate plates and other parts ...

Valentina Bordei, thyssenkrupp, discusses the optimisation of clinker coolers to meet industry demands for energy efficiency and low maintenance. In every …
Both of these factors result in an increase in clinker cooler undergrate pressure, which will result in the grate speed increasing. Accordingly, if the clinker cooler grate speed gradually increases over a one-half hour to two-hour period, the kiln may be cooling. If the grates are slowing, the kiln may be getting hotter. Summary of kiln ...
More than 40 years of designing clinker coolers and over 800 installations and engineering consulting relating to the manufacturing of clinker coolers worldwide, prove that the IKN Pendulum cooler is at the forefront of technology.. Following the stationary inlet (KIDS ®), the Pendulum Cooler is divided into separate aerated compartments.Optimized …
The cement industry includes energy-intensive processes, e.g., clinker rotary kilns and clinker grate coolers. Clinker is obtained through chemical and physical reactions in a rotary kiln from raw meal; …
The compact design is a perfect fit perfectly for both Greenfield projects as well as cooler replacements for wet and dry kiln systems. The ETA cooler is particularly suitable for the use of Waste Heat Recovery(WHR-) systems and recirculation (i.e. Duotherm-) Systems.

The grate cooler is a quenching type cement cooler applied for the cement manufacturing plant. According to the movement mode of the grate, the grate cooler can be divided into three types, rotary type, vibrating type, and push-type grate cooler, with the development of cooler technology, push-type grate cooler is considered the most common clinker …
Case Studies: Modern Clinker Cooler Tech . Clinker cooler upgrades typically increase throughput and energy efficiency. In turn, the latter reduces emissions. Mokra Plant in Brno, Czech Republic . The Mokra cement plant opened in 1969. The plant's existing grate cooler was inefficient, due in part to a clinker bed height of only two feet.
After operating the only two-layer cooler ever successfully commissioned, the German cement producer Phoenix Zement decided to install the polytrack® eco clinker cooler at its Beckum plant. Thanks to great team effort, the eco cooler was installed during the winter shutdown in January 2022, and started up smoothly at the end of February.
The clinker cooler is an essential element in the production of cement. The cooler, as the name implies, cools the clinker to manageable levels while transporting it away from the kiln. It also recovers heat from the clinker for use in the kiln, precalciner and other areas. In addition, the cooler sizes the clinker, breaking up large pieces.
