The waste air stream is another distinct disadvantage of the grate cooler design, and limited its popularity until the 1980s. Rotary and planetary coolers operate under suction and although noisy, produce little atmospheric pollution. The waste air of a grate cooler naturally contains a large amount of gritty clinker dust.
We are the leading manufacturers and exporters of grate cooler, industrial clinker cooler and clinker grate cooler. It is basically supplied in two independent entities inlet stationary inclined grate and reciprocating grate cooler, industrial grate cooler, industrial clinker cooler, grate cooler manufacturers, grate cooler suppliers
Unprecedented cooler performance Reciprocating coolers play a major role in the reliability and efficiency of a Cement plant. Magotteaux’ smart engineering of classic cooler grate plates coupled with unique alloys development (Xcc ® technology) allow you to reach unprecedented performance of your coolers on many aspects.

GRATE COOLERS / 3.1 The Reciprocating Grate Cooler / 3.1.7 Clinker Crushers 3.1.7 Clinker Crushers All kiln systems produce larger than normal clinker lumps more or less frequently. Large balls of material enter the cooler when coating drops during kiln upsets.
(22) 07.08.2015 (43) 08.02.2017 (57) A cement clinker cooler grate 1 for cooling and conveying cement clinker in a forward direction 2 comprising a grate surface for supporting the clinker, which is conveyed by some reciprocating conveying means 35, e.g. a reciprocating row of grate plates 35, being arranged one besides of the other on a
To perform these functions efficiently, the PGC® reciprocating grate cooler is divided into three zones, which are ideally suited to the different tasks: The purpose of the cooler inlet section is to rapidly and uniformly distribute the clinker discharged from the kiln and aerate it
In addition, lower grate speed has had a positive effect upon grate wear rates. High undergrate pressures and airflows adversely affect the conveying action of a reciprocating grate. High air pressures can reduce the friction between the clinker and the grate, which in turn can speed up the movement of the clinker toward the cooler discharge.
6-10-2012· The Fons Delta Cooler sets new world wide standards for clinker coolers. Our improved technology has solved a number of problems often experienced clinker coolers, which are cruicial to the efficiency and economy of the project.
The invention relates to a reciprocating grate cooler in which the drive arrangement is enclosed by a drive housing, the interior of which is closed off so as to be airtight against the atmosphere, but by contrast has a pressure equalization connection to the interior of the cooler housing. Such a reciprocating grate cooler is distinguished by
Modern reciprocating grate coolers. The clinker cooler is based on the aeration system, consisting of HE Module and Fishbone Aeration, which has proved successful over many years. Examples are used to demonstrate that consistent linking of process technology,
Cross-Bar® Cooler for efficient clinker cooling FL. Unlike other cooler designs, the FL® Cross-Bar® Cooler separates the clinker conveying and air distribution systems. Reciprocating bars effectively convey, mix and shear the clinker within the cooler. As the bars gradually wear over time, there is no effect on cooler .
The reciprocating grate action provides particle turnover to expose each clinker surface to contact with air current; A comparison made between various types of coolers, claimed generally 5% more heat recuperation of the reciprocating cooler versus the traveling grate cooler
Clinker Cooler Type 1. Grate Cooler • Cross flow heat exchange through clinker bed with cold air • Grate movement : reciprocating; consisting of movable row (reciprocating) & fixed row • Grate can either be horizontal or inclined (3 o ) • Occurrence of waste air requires additional equipment for dedusting • Capacities of up to 10,000
A cement clinker cooler grate 1 for cooling and conveying cement clinker in a forward direction 2 comprising a grate surface for supporting the clinker, which is conveyed by some reciprocating conveying means 35, e.g. a reciprocating row of grate plates 35, being arranged one besides of the other on a reciprocating cross beam 36, provides
The Revolving Disc Cooler RDC: A perfect cross flow heat exchanger with 100% transport efficiency. No reciprocating movements and related wear any longer. We introduce a simple but innovative clinker cooler with unbeatable logic. CemProTec makes the clinker cooler go round. Please follow us. Reciprocating clinker cooler:
Reciprocating bars effectively convey, mix and shear the clinker within the cooler. As the bars gradually wear over time, there is no effect on cooler operation and thermal efficiency stays high. Horizontal design for excellent clinker transportation. The Cross-Bar® Cooler’s drive mechanism is designed to obtain optimal transport efficiency.
CLINKER COOLER 2 CLINKER COOLER Reduce clinker temperature from approx. 1400 o C to approx 100 ~ 200 o C The heat of the incoming clinker is recuperated in the secondary air of Kiln An efficiency of incoming clinker heat usually lies within 65 ~ 75% 3 Clinker Cooler Type 1. Grate Cooler Cross flow heat exchange through clinker bed with cold air
This is an inclined arrangement of specially designed anti spillage Grate plates, arranged in downward steps formation. These Grate Rows do not move. The Castable cover is shaped in such a way to have spread of hot clinker on grate without void.
Full text of "Holderbank Cement engineering book" In contrast to the reciprocating grate cooler, the clinker does not tumble over plate edges, but remains as undisturbed layered bed from inlet to discharge. ♦ Heat exchange Heat exchange takes place,

rapidly cool ("quench") the clinker, thus preserving reactive metastable high-temperature minerals in the clinker and maximising its strength potential; Grate coolers: The list represents the coolers initially installed with the kilns, and excludes retrofits. The type titles are clickable.
This function will be carried out by our successful and proven Clinker Distributions System “CDS”, which is working remarkable well in reciprocating grate coolers. Such CDS is located above the slowly rotating disc, which is covered by a dead clinker layer. Our Smart Blade grate system forms the RDC grate
