Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.

In this unit, the input materials (Clinker, Gypsum, Pozzolana, and Limestone additive) are proportioned and ground in Cement mill (one Closed circuit ball mill in line 1 and two Roller press+closed circuit ball mill in line 2) based on the type of cement to be produced keeping the quality of cement equal or above the required standard.

The purpose of a cooler is, obviously, to cool the clinker. This is important for a several reasons: From an engineering viewpoint, cooling is necessary to prevent damage to clinker handling equipment such as conveyors. From both a process and chemical viewpoint, it is beneficial to minimise clinker temperature as it enters the cement mill.

The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.

Cement Process & Energy Saving. Addition of Grinding Balls Watch raw mill SEC daily and add grinding balls in right timing →10% energy saving expected Ball diameter shrinks as time passes due to erosive effect This leads to gradual increase of raw mill SEC Filling level of grinding balls is also important in grinding efficiency Optimum level of filling should be maintained.

The pulverization of coal is performed in the coal mill, while the hot flue gasses from PH (Hfg 4) are used for preheating and drying of the raw coal. The stream of preheated coal (Fl ph) is then transferred into the rotary kiln burner. A planetary clinker cooler (CC) is used to cool down the clinker from approximately 1400°C to 100°C.

The thermal SEC is the energy (kcal) required to produce 1 kg of clinker. 3.3.1.6.1.1 Normalized Baseline SEC The simple calculation of gate-to-gate SEC does not account for variations in plant-specific factors such as export and import of clinker, conversion of the product mix to equivalent major product, and the CPP's net heat rate and ...

1.1.10 Clinker storage & transportation . The cooled and crushed clinker through chain bucket conveyer comes to clinker silo for storage, with capacity of 33000t, and storage life of 16.5 days. The clinker out of silo is sent to the clinker batch silo before cement mill by belt conveyor. 1.1.11 Gypsum crushing and pozzolana transportation

formed into clinker – is the key. This transformation involves both chemical and physical processes. The microstructure of clinker is a function of kiln feed properties and the pyroprocessing conditions. Knowing what happens where, why, and how, can lead to optimising pro-duction, costs, and quality. In turn, the clinker microstructure and ...

The precalcining technology is a technical leap of cement calcining process, with a series of excellent properties and characteristics such as high quality, high efficiency, and low consumption. Add a precalciner between the preheater and the rotary kiln, or use the uptake flue at kiln end, and set up a fuel injection device to make the ...

The preheating and partial precalcining of the raw material are completed by the cyclone preheater, instead of the partial function of the rotary kiln, shorten the length of the rotary kiln, and the gas heat exchange process in the kiln is carried out in a stacked state, and moved to the preheater in a suspended state.Under the process, the raw material can be fully mixed with …

Coal fines are usually prepared by air swept coal mill or vertical mill. In order to produce high-quality clinker, the fineness of coal fines should be controlled at about 12%, and its moisture content should be controlled within 1.0%. The machines that are usually used to dry the coal fines are rotary dryers.

If one or no additions are required you will have 2 or 3 bins of clinker for extra storage capacity. The total inlet moisture must be kept under 1,5%. The container number #2 has a 450kW ball mill of extreme simplicity to ensure maximum reliability and low maintenance. Nevertheless today's most advanced technology has been used in its ...
