(a) General. The provisions in this section apply to each kiln and any alkali bypass associated with that kiln, clinker cooler, raw material dryer, and open clinker storage pile.All D/F, HCl, and total hydrocarbon (THC) emissions limit are on a dry basis. The D/F, HCl, and THC limits for kilns are corrected to 7 percent oxygen. All THC emissions limits are measured as propane.
Alibaba.com offers 263 clinker cooler products. About 67% of these are cement making machinery, 3% are centrifugal fans, and 2% are dust collector. A wide variety of clinker cooler options are available to you, There are 255 clinker cooler suppliers, mainly located in Asia.
Coolers are essential parts of rotary kiln systems. Clinker leaves the kiln at 1200°C or more. Clinker at this temperature has a heat content of 1.22 MJ/kg and must be cooled in order to: avoid wasting this heat energy; obtain clinker at a temperature suitable for grinding - less than 100°C
the cooler. To convey the clinker bed the transport tracks are moved forward together and are then individually moved back. By varying the transport stroke length and frequency, the conveying speed of the clinker bed and thus the clinker bed depth and the clinker throughput can be optimally controlled over the entire width of the cooler.
Typically kiln feed used to make cement clinker enters the cooler at 1400°C and cools to about 150°C as it travels to the outlet. Because the service environment is very abrasive and subject to thermal shock on a regular basis, HarbisonWalker International's products are focused mainly on abrasion resistance.

Low-cement castables, including Kricon 32-70, QuikTurn 32-70, and the R-Max product family, offer exceptional service for the castable nose ring. Cement clinker is discharged from the kiln into the clinker cooler. The clinker is moved from the cooler inlet to the discharge by the reciprocating motion of perforated grates.
Clinker Cooler. After cement is dried by being put through a rotary kiln and converted to clinker, it needs to be cooled. Cooling tunnels are used to reduce the temperature of the clinker from over 2000°F to a workable 200°F. These tunnels typically use forced draft fans to push the cooled air through the clinker.

Wahl has developed an engineered precast cooler curb block which has been successfully used in modern clinker coolers. Photograph on the right is of a recent inspection of Wahl precast cooler curb blocks after 5 years in service in a modern 1.7million ton/yr cement kiln in the USA.
I found this passage in a book called "Clinker Coolers" by Hans E. Steuch (Chapter 3.8, p494-495), which may be helpful to you;-"The fact that especially large diameter type kilns tend to discharge fine clinker on the kiln's load side and coarse clinker on the opposite side can make it difficult to get good clinker distribution.

Clinker Coolers Cameras The Grate Cooler is an area where a large amount of process heat can be recovered. The Mirion Spyrometer™ system can be used to measure temperature profiles both across and down the bed to optimize the heat recovery to the tertiary air duct.
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. The early coolers, like the kilns, made little effort to trap this, and …

This is called clinker. The hot clinker next falls into a cooler which recovers most of its heat, and cools the clinker to around 100 °C, at which temperature it can be conveniently conveyed to storage. The cement kiln system is designed to accomplish these processes. Early history
Kiln temperature monitoring is essential to ensure product quality, optimize throughput, minimize emissions, and prevent damage to the kiln shell and material handling conveyors. Process Sensors IR Temperature sensors are used on material preheat, mid-kiln, burning zone, kiln shell and clinker cooler …
Cement rotary kiln is the main euipment for sintering cement clinker. The cement rotary kiln produced by our company can be used for chemical industry and etc. Through technical renovations, the rotary kiln sintering system made by our company has adopted high measuring precession plunger pump,variable speed adjusted valve,stainless steel ...
It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials.From a cement performance viewpoint, faster cooling of the clinker enhances silicate reactivity.
The FL® Cross-Bar® Cooler is the latest evolution in clinker cooling technology. Based on proven FL systems, it incorporates advanced clinker cooling innovations to give you low installation, maintenance and operating costs – and a very attractive total cost of ownership.
The clinker discharged from the rotary kiln enters the rotary cooler and is rapidly quenched with water from 1,400°C to 600°C. The clinker subsequently passes through the roll crusher, which produces grain sizes < 50 mm. Finish cooling from 600°C to the ultimate temperature of approx. 100°C is performed on the vibrating grate with air.
These changes also affect the core of the entire cement producing process: the clinker formation in the rotary kiln. Thus, in order to maintain or even improve clinker quality (and output), we need a better understanding of the development of clinker properties inside the kiln to react upon the impact of process changes.
The Air-Quenching shaking grate Clinker Cooler was developed more than 20 years ago as an improved heat recuperating cooler for use with rotary kilns. It was designed to air quench and cool large quantities of hot clinker rapidly, and to recover and return to the kiln a major portion of the heat from the clinker.
