Actual cooler loss (Kcal/Kg clinker) 149: 110: Standard cooler loss (Kcal/Kg clinker) 131: 92: Clinker temperature (Celcius) 112 degrees + ambient: 57 degrees + ambient The clinker cooler is mainly used to cool and transport the cement clinker. Energy consumption Energy consumption refers to the power consumption of cement cooler in daily operation. The 4th generation cooler has the following features: The grate plate adopts clinker self-protection technology and its service life can be longer than 5 years. The following are several important factors affecting the cement clinker quality. To maintain overall plant capacity, your cooler must handle a constant throughput of clinker. It starts with crushers that feed raw material storage. Keeping clinker dust levels as low as possible (Figure 3) has many benefits to cooler, kiln and downstream plant performance. The tailor-made engineering by FTI will enable the clinker cooler replacement to be carried out with reduced initial investment costs, low energy . In June 2012, the 6MW waste heat generator set was put into operation, generating capacity of 80,000 to 100,000 kw per day. This is important for a several reasons: From an engineering viewpoint, cooling is necessary to prevent damage to clinker handling equipment such as conveyors. .

And excessive wear of cooler parts can lead to inefficient cooling processes and even production stoppages. A standard cement plant with a daily output of around 3000 tons of clinker requires around 2500-4000 kJ/kg of clinker of energy [3]. Requirements for Clinker Cooler at Major or Area Source of HAP Constructed after May 6, 2009 . It is responsible for 10% of the total production of Portland cement and 12.5% of clinker production in Turkey [12]. The purpose of a cooler is, obviously, to cool the clinker. The simplest way to cut your clinker cooling costs. After the clinker is fired, the temperature begins to decrease. Generally, the temperature of the cooled clinker is usually between 70-300 . The clinker cooler is a critical component in the production of quality clinker in a cement plant. Waste heat from the kiln exhaust or the clinker cooler vent, or auxiliary heat from a standalone air heater before pyroprocessing, is often used to further dry the raw materials. Clinker leaves the cement kiln usually at more than 1200 and it carries the heat content about 1250-1650 kJ/kg. At this point, the mixture is called kiln feed. According to this analysis, the standard and actual cooler losses have been calculated as 519.16 kJ/kg.cl and 595.86 kJ/kg.cl, respectively. LTD. NAKTAJHIJ-1, JANAKPUR, DHANUSHA, .

Here it gradually cools. UTCL plants are commissioned three years ago and presently these lines are operated upto 11,800 t/d. In this study the clinker cooler performance development is intended from the viewpoint of capacity increase and energy consumption using cement production plant actual figures. But the efficiency gains extend back from the cooler through the pyroprocess. Being kiln is the heart of Cement plant, Clinker cooler is the heart of the Kiln. AGICO supplies 2 types of kiln cooler equipment for cement production line, one is grate cooler, the other is rotary cooler, grate cooler is more efficient in cement plant, rotary cooler is suitable for many other industries.Grate Cooler is a type of quench cooler. The preheated raw mix feedstock is calcined, then burned in a rotary kiln (16) to form clinker. It has a unique longitudinal sealing structure to ensure that grate bed has no leakage during operation, lifetime is 1 year. A typical cement plant producing about 3000 tons clinker per day requires energy input of about 2500-4000 kJ/kg clinker. The plant has industrial water treatment unit which is a sand filter. While total electrical energy consum ption for cement production is a . Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. Our Cross-Bar Cooler takes clinker cooling technology to another level. Uses: The grate cooler is an important main equipment in the clinker burning system of the cement plant.

Cement clinker is made of limestone, clay, and iron, these main raw materials are mixed in proper proportions, burned to partial or total melting, and finished cement is obtained by cooling. Knowing about clinker cooler design is vital to make your plant green! 3. 3. Venturi scrubber has shown to be very efficient in removing . 1. Cooling clinker The clinker temperature is an important indicator of the grate cooler performance, which reflects the cooling efficiency of the grate cooler, and also creates conditions for the conveyer, storage, and cement grinding of clinker in subsequent processes. Clinker Cooler Atlanta. The plant includes industrial processes related to the production of white cement. Much like the rotary kilns that feed them, clinker coolers in cement making are also subject to extremely high operating temperatures and dust levels. Rain Cement's South India-based Ramapuram plant has achieved impressive performance results following the successful replacement with an FLSmidth Cross-Bar cooler. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage. A good clinker cooler can help cement plant reduce energy consumption from two aspects: one is to improve the cooling efficiency and reduce the power consumption of clinker cooler itself; the other is to reduce the coal consumption of rotary kiln and preheating system by improving the heat recovery rate. Clinker grate cooler Jun. In the production of cement clinker, the clinker used in a clinker cooler process heat, for example, used to generate electricity. A grate cooler can be regarded as a simple heat exchanger through which the clinker passes across or counter to the cooling air flow and a direct heat transfer takes place between the hot clinker and the cold cooling air. thyssenkrupp has responded to these For example, low fugitive air emissions result in a highly-efficient heat recuperation, raising the overall process efficiency of the plant. Based on years of research, development and operational experience, it combines simple installation and low maintenance with advanced design to give you efficient clinker cooling and low operating costs, however demanding your operating environment. Each clinker cooler at any portland cement plant; Emission and Work Practice Standards - General: 63.1343(a) 63.1343 What standards apply to my kilns, clinker coolers, raw material dryers, and open clinker Lime Saturation Factor When the clinker is rapidly cooled, the formation of mineral crystals in it is inhibited. Cool Down Innovative solutions for the cement industry made in Germany. The ESP has been found to clean gas coming out from rotary kiln, saw mill, alkali by pass, clinker cooler, cement and coal mill [90]. Manual speed control makes it possible to maintain proper cooling conditions under varying loads. Clinker residence time in cooler Radiation Heat Losses RHL Convection Heat Losses CHL Forced Convection Heat Losses FCHL. The crushing of granite, limestone, cement clinker, quartz stone, slag, iron ore, bauxite, and other minerals. SEND INQUIRY. 1400oC Reduces To 100 .. 200oC. In the process of clinker production, strict control of these factors can ensure the production of high-quality, high-yield clinker. The process of the company is illustrated in Fig. 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 the over-arching requirements to reduce energy consumption and minimise the impact on the environment. The desired maximum recuperation of the heat from the clinker cooler for use in the Inside the cooler, hot clinker will direct contact with the cooled air blown from the air blower to realize fast cooling. . For grinding, large cement plants use high speed roller mills or bowl type grinding mills, and smaller plants use tube mills packed with paper bags filled with iron grinding balls. The performance of the grate cooler will directly affect the production efficiency, energy consumption, and clinker quality of the kiln system. Clinker cooler is also called cement cooler, which set behind the cement kiln for clinker cooling.
