The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃, and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.7 m 3, the air consumption efficiency will be 15% lower than that of other cement ...
Nov 04, 2020· This is the place where the oxides in raw materials will be consolidated to shape mixes in the clinker. The melded mass transforms into a nodular type of size 3 mm to 20 mm known as clinker. At that point, the clinker is cooled under controlled conditions in a rotational cooler. The clinker is put away in storehouses or receptacles.
It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2-3% percent of GYPSUM. Several types of Portland cement are available. The most common, called ordinary Portland cement (OPC), is grey, but white Portland cement is also available.
Clinker means the product of the process in which limestone and other materials are heated in the kiln and is then ground with gypsum and other materials to form cement. Clinker cooler means equipment into which clinker product leaving the kiln is placed to be cooled by air supplied by a forced draft or natural draft supply system.
The hot clinker next falls into a cooler, which recovers most of its heat, and cools the clinker to around 100 °C, a temperature it can be conveniently handled.
Jan 20, 2016· During clinker production, high- and low-temperature gases discharged from the kiln, clinker cooler, and pre-heater are used for other purposes, such as firing the kiln, drying raw materials and coal, and driving the steam turbine to generate electricity. The recycle rate of waste is 70.71% in the surveyed plant . The available waste energy is ...
After sintering, the clinker will have a high temperature. They will cool down at the end of the kiln firstly and then enter the cooler placed behind the rotary kiln for further cooling. When clinker drops to indoor temperature, it will go to the next step. Cement Grinding: cement grinding is the final stage in Portland cement manufacturing. In ...
Cement clinker. Cement clinker dust (CKD) is a problematic waste derived from the cement industry which may cause some problems in clinkering kiln operations and cement performance. CDW has to be discarded despite its hydraulic properties due to high content of chlorine, sulphur and alkalis Clinker is a nodular material produced in the kilning stage during the production of cement and is used ...
White cement clinker can be efficiently produced using a kiln 10 for sintering cement clinker and unloading the cement clinker from the kiln 10 to a clinker cooler 30 for ex-changing thermal energy between the hot clinker 33 and a gaseous coolant by subjecting the clinker 33 to a flow of said gaseous coolant to thereby cool the clinker 33 and in return heat the gaseous coolant, if the gaseous ...
Cement manufacturing has several opportunities for WHR, specifically in the process step where the clinker material is produced. For clinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500°C. The kiln and clinker cooler have hot exhaust streams where waste heat could be recovered.
The specific water flow [kg/kg. clinker] = Net Water Flow [kg/hr] / Total Clinker [kg/hr] 3.1.2 Cooler Output The clinker output from the cooler is expected to be 1 kg provided no loss in mass. 3.1.2.1 Excess Air The cooler excess air was found by measuring the temperature and static pressure at cooler at cooler ESP stack.
After the raw materials are calcined to clinker, the temperature begins to decrease. Finally, the high-temperature clinker discharged from the rotary kiln is cooled by the cement clinker cooler to the temperature that the downstream transport, storage, and cement mill can bear. Meanwhile, the heat of the high-temperature clinker is recovered by the cooler to improve the thermal efficiency and ...

widely used for raw material and coal grinding in the cement industry. The adoption of an external raw material recirculation system has further improved the efficiency of VRM. These mills can also utilise large quantities of hot gases from the pre-heater and even the clinker cooler and thus are
The spatial extent of project boundary includes all process units related to the manufacturing of clinker in the cement kiln, from reception of raw materials and fuel to the delivery of clinker to the cooler. Transportation of raw materials, alternative raw materials, fuels and electricity generation sources are
Cooler. Clinker cooler serves two main objective of cooling clinker from temperature of about 1350 0C to the temperature (65-150 0C) where it can be handled by conveyors like pan conveyors, chain, Elevators etc. and heat recovery from hot clinker coming out of kiln. A huge development has happened in clinker coolers designs and types as well.
Manufacturing methods and plants for carrying out methods of manufacturing cement clinker including diverting gases from a separation cyclone for a calcined cement material. The diverted gases are cooled to a temperature of 850° C. or less by introducing raw cement materials into the diverted gas stream.
The grate cooler is a quenching type cement cooler apply 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 as the most common clinker cooler in the cement production line.
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.
storage piles. The material handling equipment used to transport clinker from the clinker coolers to storage and then to the finish mill is similar to that used to transport raw materials (e.g. belt conveyors, deep bucket conveyors, and bucket elevators). To produce powdered cement, the nodules of clinker are ground to the consistency of powder.
White cement is more difficult to manufacture and has higher prices than normal Portland cement. White Portland cement clinker is made of pure raw materials, such as pure kaolin, pure quartz sand, pure lime or chalk, at a higher temperature (1500 ℃ ~ 1600 ℃). It is generally used for interior and exterior decoration of buildings.
