cement factory cost | how much does it cost to start a cement plant?

If youre thinking about set up a cement factory (or cement plant), you must weigh the pros and cons of it many times. There is no doubt that youve considered all your musts, such as locations, cement plant design, cement plant layout, etc. But the most important thing is absolutely cement factory cost how much does it cost to build a cement factory? Maybe you also want to know the potential investment you dont see coming.

According to the data we know, the total cost of a cement plant is estimated to be US$ 75 to US$ 100 per ton. One thing to be clear, this is just an estimation, in the real cement plant building, the cement factory cost is affected by various factors, including the significant difference in cost of land, availability of limestone mines, etc.

The cement factory cost is based on changing factors like size, location, labor, raw materials, and current real estate trends, which make it impossible to nail down a perfectly accurate, one-size-fits-all answer. So lets list the cost item needed in building a cement factory, everyone can get your own plant according to these items.

As we all know, the cement production line is made up of various types of cement equipment, the cement factory cost depends on the cement factory machine you choose. For some buyer who has abundant funds, might choose high-quality equipment, which increases the cost of the cement production line. At the same time, high-quality cement plant also brings considerable economic benefits and market returns.

At present, the new-type cement plant has advantages of high profit, quick effect, high efficiency, energy saving, environmental protection, easy operation, and low cost. The hot-sale cement plant is composed of following cement factory machines:

If you are ready to buy a cement plant, it is suggested to choose a cement plant manufacturer with a large scale and strong strength, which will provide full cement equipment and service, also ensure the quality and performance. In general, for the customer who wants to buy the whole cement production line, the cement plant manufacturer will give more preferential policies. On the contrary, the strength of small-scale manufacturers is limited, cement equipment types are not complete enough, need to buy from different manufacturers, not only trouble but also increase the cost of investment.

Investors have different requirements for the daily output of the cement factory, so we can find a large capacity cement plant and mini cement plant in the real case, and the investment capital will also be different. Generally, the higher the output value, the higher the investment, because the model requirements for cement equipment will be higher, and the price of equipment will naturally rise, but the value of the benefits to customers will be greater.

Enterprise competition is a side factor that affects the cement plant price. The more intense the competition, the cheaper and more affordable cement equipment prices. On the contrary, if there are fewer cement plant manufacturers and the competitiveness is weak, there is no obvious threat between the companies. Cement plant prices will generally maintain a normal state or relatively increase, which is a manifestation of natural laws.

Except for above elements, there are some other factors involved in the cement factory cost, such as labors, raw materials cost, cement plant design and so on, labors cost is always related to the location and your scale of cement factory; as for the cost of the raw materials, the place where is near mineral resource will be recommended, which will reduce your transportation cost. For most large cement plant manufacturers, they can provide custom solutions to cement plants, also supply the EPC project for equipment or cement plant.

00 Limestone Quarry and Crushing PlantThe major raw material for cement production is limestone. The limestone most suitable for cement production must have some ingredients in specified quantities i.e., calcium carbonates, silica, alumina, iron, etc. Typically, cement plant locations are based upon the availability of good quality limestone in the vicinity. The quarrying operations are done by the cement producer using the open cast mining process. Quarrying is done through drilling and subsequently, using heavy earth moving equipment such as bulldozers, payloaders, and dumpers. The quarried raw material is then transported to the cement plant, using mechanical conveying equipment such as ropeways or belt conveyors, or by vehicles like wagons and trucks. The quarried limestone is normally in the form of big boulders, ranging from a few inches to meters in size. These varying sizes of limestone need to be crushed to a size of about 10 mm in order to be prepared for finish-grinding. There are mainly two types of crushers available for this purpose- compression type or impact type crushers. There are many types of compression type crushers such as jaw crusher, gyratory crusher, cone crusher, roll crusher. The impact of technology is used in a hammer crusher/impact crusher. Crushing is done either in two stages or in a single stage. In the two-stage crushing system, a compression type crusher is used in the first stage for raw crushing, followed by impact/hammer crusher in the second stage. In single-stage crushing, an impact-type crusher is used. The selection of the crusher depends mainly on the characteristics of the raw materials. This selection is further guided by the particle-size distribution requirements of the downstream equipment such as raw mills and lastly by financial considerations.

The raw material is stored at either the quarry or at the plant. Typically, circular or longitudinal stockpiles are used to store the material. A number of layers are stacked in circular or longitudinal piles and are reclaimed in transverse, cross-sectional slices. The stockpiles consist of separate layers/piles of different kinds of raw material. This is used in segregating the raw material quality-wise. The required quantity of the various raw materials is thus easily extracted for use. The extraction of different qualities of raw material is monitored and controlled in order to maintain the desired composition of raw meal, suitable for feeding into the kiln.

In order to get the required composition of raw material, certain additives such as iron ore, bauxite, laterite, quartzite, and fluorspar are added in the required quantities. These additives are stored at the plant in separate hoppers and are extracted using belt conveyors in conjunction with belt-weighing equipment. This ensures that only the required quantities are extracted and added to the raw material.

The raw material is finish-ground before being fed into the kiln for clinkering. This grinding is done using either ball mills or vertical roller mills (VRM). The raw material is simultaneously dried. Ball mills use impact with attrition principles for grinding the raw material. Inside the ball mills, various sizes of balls are used and classifying liners are used to maintain the position of different sizes of balls. The larger sized balls are utilized for impact grinding and the smaller balls for attrition. VRM uses the compression principle to grind the raw material. The choice between a ball mill and VRM is governed by many factors such as the moisture content of the raw material, the size of the plant, the abrasiveness of the material, the energy consumption levels, reliability, and finally financial considerations. Ball mills are suitable for low and medium moisture content in the range of five to six percent and are preferred for abrasive material. The main advantage of VRM is higher grinding efficiency and the ability to accept material with higher moisture content. Normally the energy consumption level in VRM is 10 to 20 percent lower than in ball mills.

Normally there are various sources of limestone, each with different qualities, which are added with various additives to get the required composition of raw mix. As there are various sources of raw materials, it becomes necessary to blend and homogenize these different materials efficiently to counteract fluctuation in the chemical composition of the raw meal. The variations in the composition of kiln feed have very adverse impacts on the efficiency of the kiln. It results in undesired coating and ring formation inside the kiln. In order to blend and homogenize the raw materials properly, continuous blending silos are used.

The most important activity in cement manufacturing is clinkering (or burning) of raw material. Clinkering takes place in the kiln and the preheater system. Preheater systems offer heat transfer from the hot kiln gases.

The conditioning tower is used to reduce the temperature and to increase the moisture level of the dusty exhaust gas from the kiln, before it is passed through the baghouse and ESPs. It is called a conditioning tower because it conditions the hot gas, thus making it more suitable for the ESP and baghouse to extract dust from it. Electrostatic Precipitators are used in cement plants particularly for removal of dust from the exit gases of cement kilns and from the exhaust air discharged by dryers, combined grinding and drying plants, finishing mills, and raw mills through water injection. Through ESPs, the dust-laden gas is made to flow through a chamber usually horizontally, during which it passes through one or more high voltage electric fields formed by alternate discharge electrodes and plate type collecting electrodes. By the action of an electric field, the dust particles, which have become electrically charged by negative gas ions that are formed at the discharge electrodes and attach themselves to the particles, fly to the collecting electrodes and are deposited there. The dust is dislodged from these electrodes by rapping and thus falls into the receiving hopper at the base of the precipitator casing.

A kiln is the heart of any cement plant. It is basically a long cylindrical-shaped pipe and rotates in a horizontal position. Its internal surface is lined by refractory bricks. Limestone and additives are calcined in this. The output of the kiln is called clinker.

The output of the kiln is stored before it is fed to the cement mill for conversion to cement. This storage is called clinker storage, if it is used for clinker storage purpose. If the storage space is used for gypsum storage, it is called gypsum storage. The storage may be of silo type or covered stacker reclaimer type or simply a gantry type. Silo type clinker storage has the advantage that there is no dust pollution and spillage of clinker. The same advantage can be achieved through the stacker reclaimer type as well. However, there is a little bit of dust generated. Gantry type is not used in modern cement plants because of its environmental unfriendly nature.

Limestone coming out of the quarry is crushed in multiplestages in a sizing plant before it is put in limestone stockpile. Crusher are mainly of two types viz. Jaw crusher and Hammer crusher. Jaw crusher is basically a simple mechanism having two plates one fixed and another moving. This is also called primary crusher. Hammer crusher has got metallic hammer mounted on the axes and the sizing achieved by the impact of the hammer.

The coal mill building houses the mill for grinding lumpy coals. This fine ground coal is used for burning in the kiln. The mills used for coal grinding and drying are either trumbling mills (tube mills) or roller mills.

Clinker, along with additives, is ground in a cement mill. The output of a cement mill is the final product viz. Cement. In a cement mill, there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates, the crushing action of the balls helps in grinding the clinker to a fine powder. The term baghouse is applied to large filters containing a number of tubular bags mounted in a usually rectangular casing. The dust-laden air is drawn through them by suction. The baghouse is used to remove dusty particles from discharge of different equipment such as cement mill, coal mill, and kiln. In a baghouse system discharge gas containing dusty particles is passed through a series of bags made of strong fabrics.
