In modern cement plants, the clinker cooler is the key to high recuperation effi ciency and low clinker outlet temperatures at the lowest possible energy consumption. + Compact design + Low power consumption + Effi cient clinker cooling The Pendulum Cooler® is designed as single grate with a roll crusher at the end or as double grate with ...
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
Yixing tianshan cement co., LTD. 2500 t/d production line put into operation in August 2003, adopt LBT32216 grate cooler, grate bed effective area of m2, the first section of the grate bed tilted 3 ° to decorate, the first row of grate plate grate plate for the activity.
Pdfgrate Cooler In Cement Plant In Plate Types. We manufacture this critical heat resistant castings component for the cement plants . these heat resistant castings are used for working temperature upto 1100 degree celcius. following are the various types of castings that are needed by the cement plant cooler grate plate
Energy Distribution of Grate Cooler. The tertiary air flow is used as a source of energy for heating kiln feed at the precalciner (Air flow rate for pulverized coal heating can be ignored as low volume required). The secondary air flow is required by the process system, which is high energy bearing air from the Kiln.
Grate cooler is the main equipment for cooling clinker in new dry cement in the use of the "snowman" phenomenon often is a grate cooler snowman?The so called grate cooler pile snowman is a kind of image of the name, is actually a block is, in the grate cooler in front of the wall of the rotary kiln tube to the back of the unloading chute, the moving grate ...
The aim of any cooling system is to cool the clinker as quickly as possible, to set and maximize C3S content. Simultaneously, it is important to capture and reuse the heat liberated by this process. In the grate cooler, the clinker enters at a temperature of around 1,200°C, rapidly spreading its heat into the grate and surrounding refractories.
♦ Middle air (grate cooler only) is extracted from the cooler roof if drying of process materials requires a temperature level which is higher than the waste air. If the quantity is small, up to 450°C can be expected at normal cooler operation. ♦ Waste air (grate cooler only) is also called cooler exit air or cooler .
With over 800 clinker coolers commissioned around the world, Claudius Peters represents a leading role in the clinker cooling technology. Starting in the 1950''s, Claudius Peters has gained almost 70 years of experience and has been responsible for many of the innovative milestones reached in the past decades that are considered today as state of the art in the cement industry.

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 ...
The grate cooler is divided into different sections. The hot part requires a heatresistant lining withstanding the high chemical load. The colder part can be lined with standard materials like chamottebased monolithics or bricks. Click on the 3D drawing below to learn more about the Calderys offering for the grate cooler.
The cement manufacturing process consist of the following multi stages as explain in the following flow chart. Flow Diagram of Cement Manufacturing Process ... The discharge end of the Kiln is connected to the Air/Grate cooler. The pulverized coal is weighed in an electronic weigh feeder and pumped to
Jul 01, 2017· Applying grate cooler in the cement industry has provided the opportunity of heat recovery from hot clinker. In the current technology of clinker production processes, the thermal energy of clinker is used to preheat the combustion air, which is based on heuristic rules. However, in this study, the clinker production process (pyroprocess unit ...
The essential characteristic of a grate cooler is a layer of clinker spread on a moreorless horizontal perforated grate, through which cold air is blown. The grate is made of steel, and the cold air keeps it sufficiently cool to avoid melting or burning. The clinker progresses through the cooler by moving moreorless horizontally along the grate, and so the direction of the cooling air is ...

The cement industry is a highly polluting industry. We need to avoid noise and dust pollution in the production process. The cement cooler with low noise and small dust pollution is always the best choice. Rotary Coolers VS Grate Coolers. Rotary cooler and grate cooler are two hotsale clinker coolers in the market. They all have the function ...
The round drain grate, also known as a drain cover, is ideal for draining light flows of stormwater from small lawns, landscaped areas, patios, and walkways. Grate is made of solid brass and the collar is made of polyvinyl chloride, a type of plastic. The 4 in. Round Drain Grate has an open surface area of sq. in. and flow rate of 16 GPM.

In cement grate coolers, dense refractory linings backed by insulation materials often results in an unnecessarily heavy construction, which increases fuel expenditure. Furthermore, the lining can be at risk of alkali attacks, which increases maintenance costs.
Clinker coolers are classified into different types based on their design and operation. The classification of clinker cooling mechanisms is as given in figure 1. Fig. 1. Classification of Clinker coolers. Grate Cooler. Grate coolers are extensively used in cement industry to recover heat from hot clinkers coming out of rotary kilns.
In a cement plant, grate cooler is a basic machine in the calcining cement system, its main function is to make the ripe cement material to next system. At the same time, the grate cooler could offer rotary kiln and decomposing furnace hot air flow, which is the main equipment for .
