large cement plant for sale | cement plant with high production capacity

Product Name: Large Cement Production Plant / Cement Factory for Sale Capacity: 5000-10000 TPD Equipment: raw material crusher, raw meal grinding machine, storage yard, stacker reclaimer, preheater cyclones, rotary kiln, grate cooler, cement mill, etc. Cement Production: ordinary portland cement, pozzolana portland cement, white portland cement, quick-setting cement, refractory cement, etc.

In contrast to the mini cement plants, we usually call the cement plant with a clinker production capacity of more than 5000 TPD as the large cement plant. As a manufacturer who specializes in cement technology development and equipment upgrading and has over decades of cement machinery manufacturing experience, AGICO has the ability to design and build large cement plants with clinker production of up to 10,000 tons per day.

With the increase of plant scale and production capacity, the size and capacity of the crushers, cement mills, rotary kilns, and other machines in the cement plant also increase correspondingly. Therefore, the increase of plant scale should be accompanied by the growth and development of cement manufacturing machinery so as to maintain or even improve the efficiency and productivity of cement plants.

Compared with mini cement production lines, large cement plants have higher energy consumption. But take into account their output, they actually have a higher energy utilization rate and production efficiency, which can save production costs for cement manufacturers in the long run. Also, the operating efficiencies of large plants are high. The fuel consumption is around 650 700 kcal/kg clinker; power consumption is between 65-80 kWh/ton, and man-hours required per ton of cement are as low as 0.15.

AGICO large cement plants are best suited for manufacturing cement by dry process. The cement-making machines in our large cement plants include cement crushers, cyclone preheating systems, rotary kilns, cement mills, and other auxiliary equipment.

The purpose of raw material preparation in the dry process of cement manufacturing is to reduce large-sized raw materials to the proper size and mix them into homogenized raw meals. We will install the most suitable crushing machinery in the cement plant according to the raw materials and production requirements of customers, so as to achieve economic and green production as much as possible.

The application of cyclone preheating system in cement plant hugely reduces the heat loss and fuel consumption in the clinker burning process, and also significantly reduces the floor area and pollution emission of the whole plant.

The 5-stage cyclone preheater is the most installed preheating system in our large cement plants. According to customers requirements, we could design other stage preheaters for the cement plant. The cyclone preheater uses hot exhaust gas from the rotary kiln as its heat source. Before entering the rotary kiln, the cement raw meal heat exchanges with the high-temperature gas in the preheater to preheat.

The rotary kiln is where the burning phase of the cement manufacturing process takes place; it is the core part of a cement plant. The raw meal in the rotary kiln will be heated to 1,500 during the burning process to form cement clinker.

The production capacity of a cement plant is directly determined by the capacity of the rotary kiln. Our large rotary kilns can fully meet the requirement of bulk cement production. Together with the advanced preheating system, our rotary kilns could achieve high rotary speed and high output per unit volume. The good sealing effect of our rotary kilns allows them to fully recycle the waste heat and produce high-quality clinker.

Cement mills are used for raw material reduction and cement grinding in the cement manufacturing process. The cement grinding process is the final manufacturing stage at a cement plant. After this process, the clinker will become fine cement powders and ready to be packed.

The most used cement mills in our large cement plants are cement ball mills and vertical roller mills. Both of them can well undertake the task of cement grinding, we will take their production efficiencies, power consumptions, investment costs, product particle shapes and sizes, maintenance fees, and other elements into account and decide which one to use when designing a cement plant.

mini cement plant, small cement plant | epc cement plant

Mini cement plant is a new cement plant, also known as a small cement plant, which refers to the cement plant with a clinker capacity of 50-500tpd. Recently, mini cement plant becomes hotter and hotter, what are advantages of mini cement plant compared with large or medium-sized cement plant? Why choose a mini cement plant?

There is no need of heavy investment. For small and medium entrepreneurs, it is possible to participate in the business of cement. For example, some ready mixed plant companies want an independent cement supply, so they can both control the cement quality and cement price.

As for the cement plant process, mini cement plant and large- scaled cement plant share same cement manufacturing process, which include materials crushing, raw meal production, homogenization, clinker burning, cement grinding and cement packing, etc.

Small cement plant cost is higher compared to large cement plant, but still has competitiveness. It is possible to install a mini cement plant in remote areas that has problem of poor road, and the finished cement can be sold in the nearest market, no need of transportation cost.

Mini cement plant is easy to get license; the mini cement plant is generally installed near mine, so the cement material is also easy to obtain, greatly reduce the transportation cost; mini cement plant helps to promote local economy, and create more employment opportunities.

For the convenience of customers to purchase products, effectively reducing procurement costs, we make cost estimation only for reference. Take annual capacity as example, per ton clinker price range from 180 to 220 USD, the cost of delivery equipment and installation, in general, these two items will make cement plant cost increase by more than 25%.

Note: the cement capacity produced by per ton of clinker is related to factors, including cement types and maximum addition by the technical standards of different countries. So we suggest that learn technical standards as you need.

electrostatic precipitator in cement plant | esp electrostatic precipitator

electrostatic precipitator in cement plant | esp electrostatic precipitator

Electrostatic precipitator (ESP), also known as high voltage electrostatic precipitator, electrostatic dust collector, is a dust collector using electric power. It is one of the commonly used environmental protection equipment for dust gas purification. It is widely used in electric power, metallurgy, building materials, chemical industry, and other industries. Compared to other types of dust collectors, the electrostatic precipitator has the advantages of less energy consumption, high dust removal efficiency.

The power supply of the electrostatic precipitator is composed of a control box, a booster transformer, and a rectifier. The output voltage of the power supply also has a great influence on the efficiency of dust collection. Therefore, the operating voltage of the electrostatic precipitator should be kept at 40-75kV, even above 100KV.

Electrostatic precipitators can improve collecting efficiency by lengthening the electric field length. When the dust in the flue gas is in a general state, the collection efficiency can reach more than 99%. Using 4 or 5 electric precipitators will improve efficiency. When the ESP operates for several years, the efficiency of dust collection will decrease due to electrode corrosion and other reasons.

Because the structure is easy to modularize, the dust collector can be scaled up. At present, the smoke handling capacity of a single electrostatic precipitator has reached 200X104m3/h. It is not easy and economical to deal with such a large amount of smoke by bag filter or cyclone dust collector.

The energy consumption of the electrostatic precipitator mainly includes resistance loss, power supply device, heating and insulation, and vibration motor. Because of the low energy consumption, rarely replace the wearing parts, so the operating cost is much lower than the bag filter.

The shell of the ESP adopts a frame structure with high strength, good stability. And it can be designed according to different pressure and temperature resistance requirements. The air inlet and outlet can be designed into various forms according to the process layout and flue gas characteristics, and the process layout is flexible.

The electrostatic precipitator can collect high-temperature flue gas with particle size less than 0.1um and 300 ~ 400~C. Electrostatic precipitators also can be used for high temperatures and high pressure of flue gas. The practice shows that the higher the amount of smoke, the more economical the investment and operation cost of the electrostatic precipitator.

Blocking and diversion type airflow is adopted. The airflow is evenly distributed and there is no ash blocking phenomenon. The discharge electrode is properly connected to the frame, without any disconnection.

The electrostatic precipitator uses high voltage to separate the gas and dust. The electric field is designed with a linear discharge electrode (cathode) and a platy dust-collecting electrode (anode). When dc high voltage is added between the electrodes, an uneven electric field will be generated between the electrodes due to the different forms of discharge electrode and dust-collecting electrode. When the applied DC voltage reaches a certain value, the electric field in the local area around the discharge electrode is strong enough to ionize the gas and generate electrons and positive and negative ions. The positive ions quickly reach the discharge electrode and are neutralized, while a large number of electrons and negative ions move towards the dust collecting electrode under the action of electric field force, which are corona discharge and corona current.

When the dusty gas passes through the channel between the electrodes, the electrons and negative ions in the corona current (because positive ions have a small area of action, most of the dust is adsorbed by electrons and negative ions) will be adsorbed on the dust, making the dust charged. Under the action of electric field force, the charged dust moves towards the dust collecting electrode, depositing on the dust collector plate and releasing the charge. When the dust is deposited to a certain thickness, the dust is cleaned into the dust hopper and discharged through the vibration device, and the separation process is completed.

clinker cooler - cement cooler | agico cooler in cement plant

clinker cooler - cement cooler | agico cooler in cement plant

In the calcination process of cement clinker, preheating, calcining, and cooling are three inseparable process links. As the supporting equipment of cement rotary kiln, clinker cooler (also called cement cooler) is a kind of heat exchange device that transfers heat from high-temperature clinker to low-temperature gas. It plays an important role in the cement clinker production process and directly affects the cement product quality.

Cement coolers can be divided into the rotary cooler, grate cooler, vertical clinker cooler and more. While the rotary cooler and the grate cooler are now the most commonly used cement equipment in the cement plant.

Rotary Cooler: rotary cooler is the earliest used one in the cement plant. It is similar to the cement rotary kiln in appearance and equipped with refractory lining and material lifting device inside. The high-temperature clinker enters into the cylinder from one end, contacts with the cold air from the other end under the action of the lifting device, meanwhile carries out heat exchange. It is t is usually arranged under the cement rotary kiln, with a diameter of 2.0-5.0m, a length of 20-50m and a slope of 3-4%.

Grate Cooler: grate cooler is a kind of cement cooler that cools the clinker at a rapid rate. The temperature of clinker is reduced by cold air passing through the horizontally moving material layer from the bottom in a vertical direction. According to the movement of grate, grate coolers can be divided into rotary type, vibrating type, and reciprocatinggrate type.

AGICO is a cement equipment manufacturer in China. Our rich production and export experience make our products of high quality and reasonable design. We provide attentive service and reasonable quotation which makes we are well received by overseas customers.

AGICO Group is an integrative enterprise group. It is a Chinese company that specialized in manufacturing and exporting cement plants and cement equipment, providing the turnkey project from project design, equipment installation and equipment commissioning to equipment maintenance.

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.

The grate cooler is composed of upper case, lower case, grate bed, grate bed transmission, supporting device for grate bed, clinker crusher, funnel, drag chain conveyor, automatic lubricator, cooling air unit, and etc.

The grate plate and grate bed structure are the most important parts of the grate cooler, which decide the thickness of the feed layer, yield per unit of grate bed, and working efficiency of the air supply system and heat recovery. So the development of a grate cooler mainly refers to the moderation of the grate plate and grate bed.

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. At present, the cooler manufacturers guaranteed value for this temperature is 65+ ambient temperature. Thirdly, the key is how to accelerate the cooling rate of the clinker.

After the heat exchange between the cold air and the clinker at 1200, the clinker cooling heat was recovered. According to different heat transfer efficiency, the temperature of secondary air and tertiary air is between 800~1100. Therefore, the heavy material layer above 800mm should be maintained in the high-temperature section of the grate cooler. The corresponding blower under the grate plate must be a high-pressure blower. Moreover, there should be 6-9 rows of inclined fixed grate plate here, in order to improve the heat recovery and material distribution on the grate bed.

Among the three tasks, increasing the temperature of secondary air and tertiary air is definitely the result of decreasing the clinker temperature, but not any measure to reduce the clinker temperature can increase the secondary air and tertiary air temperature, so the temperature of the clinker discharged from grate cooler should be controlled. When the cooling air of the grate cooler is increased unlimitedly; Or blindly increase the use of air in the high-temperature section; Or increase the use of air in the low-temperature section, although the temperature of the clinker discharged from the grate cooler decreases, it will not increase the temperature of the secondary air and tertiary air into the kiln, but on the contrary, it will increase the temperature of waste gas of grate cooler. At this point, the clinker heat consumption does not decrease, but increases the power consumption of the exhaust fan, and also increases the burden of the dust collector.

How does the grate cooler work? The high-temperature clinker falls into the grate bed from the kiln and is pushed along the full length of the grate bed by the reciprocating grate plate, forming a materials bed of certain thickness. The cooling air blows upward from the bottom of the grate into the grate layer, permeates and diffuses, and cools the hot clinker. After cooling clinker, the cooling air becomes the hot air. The high-temperature hot air is used as combustion air into the kiln and precalciner (pre-decomposer kiln system). Some of the hot air can also be used for drying, the excess hot air is then dusted off and sent back into the atmosphere.
