How much do you know the cement equipment? Cement equipment refers to the cement making machines that are applied to the cement manufacturing plant. Before learning the cement equipment, we learn the process of cement manufacturing process first.
In general, we can divide the cement production line into three main steps: raw material preparation of cement, clinker production, and finished cement. Each step has some cement manufacturing machines, such as raw mill, cement crusher, cement mill, cement kiln, cement cooler, cement dryer, cement silo, packing machine, etc.
As we all know, the first step of the cement production line is raw material preparation. Cement crusher is the main equipment of this step. The raw materials are fed into cement crusher by vibratory feeder; the breaking material is transported by the belt conveyor to the impact crusher for further crusher.
There are various types of cement crusher on the market, including jaw crusher, cone crusher, hammer crusher, impact crusher, and etc. AGICO Cement can provide all types of cement crusher. Our cement crusher can fully crush the raw material, reduce feed size into the mill, and increase the reaction of raw material in the following cement manufacturing process, reduce the energy consumption of the whole cement production line.
Cement mill is another necessary cement equipment of the cement plant. After raw material crushing, cement mill plays vital role in the further cement manufacturing process. Cement ball mill, vertical cement mill, and cement roller press are common types of cement grinding plant.
Cement mill has two functions of the cement production line. Firstly, cement mill is used to grind the crushed material into fine size before clinker production. A cement mill is also applied for grinding clinker into finished cement. The cement clinker grinding is the last step of the cement manufacturing process, in this step, cement mill grinds cement clinker, gelatinizing agent and other materials into the required size, which can meet the requirement of cement.
AGICO Cement adopts the advanced internal selection and special compartment device, add the activation device. The grinding tail has a special discharge grate plate, which greatly reduces the size of the grinding media of the grinding bin, greatly improves the grinding efficiency, and achieves the goal of high output and low energy.
Cement kiln is used to make cement clinker, and it is the core equipment of cement production line; usually, apply for dry method cement production. There are two main kinds of cement kiln to manufacture cement clinker. One is the cement rotary kiln, and it is horizontal and can rotate. Rotary kiln is widely applied to the cement clinker production. Another one is vertical and fixed kiln, so it is called as a vertical kiln.
AGICO Cement can manufacture cement rotary kiln with advantages of convenient and reliable operation, stable thermal regulation, and high operation rate. Compared to other rotary kilns on the market, our rotary kiln increase operation rate by 10%, production capacity by 5%-10%, widely apply for cement production line of different countries.
Clinker cooler and dryer are two necessary parts of cement clinker production. The dryer produced by AGICO can apply for various raw materials and easy to adjust. During the operation, the dryer supplies heat stably, ensures the drying quality and cement quality. The cement cooler is also used for clinker production. Using blower blowing cold air, quench the cement clinker that laid on the grate plate, decrease the temperature of clinker from 1200 to 100 and below, the cooling exhaust gas enters into the kiln as secondary air.
In fact, every cement plant requires different cement equipment. Except for the cement equipment we mentioned above, there are many other cement making machines applied for the cement plant. In the real application, as a professional EPC cement plant project provider, AGICO Cement always provides a solution according to clients needs, such as mini cement plant, VSK cement plant. We also provide single cement equipment with high quality and competitive price, welcome to contact!
Indian cement industry is one of the second largest country after China, Millions of people employing throughout the country. As Cement Plant Manufacturers serving turnkey projects in Cement Industry. Indian Cement Industry contributes a big part in our economy, foreign companies are regularly investing billions in Indian Cement industry after regulations were lifted off in 1982. At present Indian companies are building new technologies in terms of energy efficiency, safety and Production.
India is a fast growing country, has lots of potential for development in terms of infrastructure and construction sector and the cement sector is expected to largely benefit from it. Recent government initiatives are also gives a major boost because of developing 98 smart cities. Dement of cement and Plantsexpected to increase due to large infrastructure projects, leading to 45 - 55 million tonnes (MT) of cement needed in the next three to four years (according to report by Nomura Research dated October 13, 2015).
Cement is a fine powder which sets after a few hours when mixed with water, and then hardens into a solid material. Cement is mainly used to bind fine sand and coarse aggregates together in concrete. Portland Cement was first invented by Mr. Joseph Aspdin in 1824, name portland was given owing to resemblance of this hardened cement paste to the natural stone available at a place called Portaln in England.
The raw materials needed to produce cement (calcium carbonate, silica, alumina, and iron ore) are extracted from limestone rock, chalk, shale, or clay. These raw materials are won from the quarry by either extraction or blasting. These naturally occurring minerals are then crushed through a milling process. At this stage, aditional minerals are added to ensure the correct chemical composition for making cement. These minerals can be obtained from the wastage or by-products of other industries, such as paper ash. Milling produces a fine powder, known as raw meal, which is preheated and then sent to the kiln for further processing.
(1) Limestone: - Contains predominantly calcium carbonate (CaCO3) and to use in cement manufacture, it should have 42-43% lime (CaO) minimum. In cement manufacture it is prime raw material and its usage would be 90- 93%.
The raw materials mix composition would be 90-93% limestone, 2-3% clay, 2-3% Bauxite, 1-2% Iron ore in cement making. Coal is used for burning the raw mix in powdered form. Normally both imported and indigenous coal are used, coal is being imported from mainly South Africa, Australia etc. because of low ash content. Pet coke is also used as alternate fuel while manufacturing of cement.
Limestone: The basic raw material is limestone, after blasting in mines is broken into big boulders and transported by dumpers to limestone crusher where it is crushed to 15 to 20mm size.
Stacker / Reclaimer: After crushing process, crushed limestone is piled longitudinally in stacker / reclaimer. The stacker deposits limestone longitudinally in the form of a pile, later reclaimer cuts the pile vertically, simultaneously from top to bottom to ensure homogenization of limestone. Crushed limestone from pile is transported through Belt Conveyor to hopper including clay, bauxite, iron ore and other raw material. All raw materials are proportioned in requisite quantity through weigh feeders.
All this proportioned raw materials are transported by Belt Conveyor to Raw Ball Mill for grinding into powder form. After the ball mill grinding process, raw material convert in to powder which raw meal-silo where blending takes place. Blending is done by injecting compressed air. This powdered material (Raw mix) is fed to the kiln for burning and Coal also requires homogenization as it contains different ash.
Burning: Powdered raw mix material fed into 4 to 6 stage preheater from top by air pressure. The hot gases from kiln enters preheater from bottom. The powdered raw mix slides down through cyclones and comes in contact with hot air which travels from top to bottom. In preheater the temperature of raw mix powder rises to 900C. to 1000C. and nearly 90% Calcination takes place before entering the kiln.
Powdered raw mix enters the kiln at one end and the burner is situated at the opposite end. The rotary kiln rotates at the speed of 1 to 3 revolution per minute (RPM). The raw mix in the kiln melts first into liquid form and then transforms into nodules due to the effect of the rotation of the kiln. There are two zones inside the kiln, namely calcining zone and burning zone. The zone where raw mix enters into the kiln is called calcining zone. Where temperature would be 950-1000C. Burning zone starts after this zone where temperature would be 1350-1450 C
The hot clinker from kiln discharge is cooled very quickly/ quenched in air with the help of efficient coolers. The temperature of clinker is brought to 80-90 C from 1350 C. Fast cooling is very essential to get good quality clinker. If cooling is not quick, the compound stability in clinker will be adversely affected resulting in lower strength of cement after grinding. Clinker from clinker silo is transported to clinker hopper by belt conveyor. Similarly, gypsum, fly ash or any other additive are transported to their respective hoppers by belt conveyors.
