How much do you know about the cement plant equipment? Cement plant equipment refers to the cement making machines that are applied to the cement manufacturing plant. Before learning the cement plant equipment, we learn the process of cement manufacturing process first.
Cement manufacturing process
In general, we can divide the cement production line into three main steps: raw material preparation of cement, clinker production, and cement grinding. Each step has some cement manufacturing machines, such as raw mill, cement crusher, cement mill, cement kiln, cement cooler, cement dryer, cement silo, cement packer, etc.
- Raw material preparation of cement: it is a process of pre-homogenization. Most of raw materials like limestone, clay should be broken by cement crusher. For example, limestone is large and hard, crushing is necessary before grinding. After crushing, mix all materials by a certain ratio. It is also vital to grind crushed material into fine size before cement clinker production. Cement ball mill is always applied to manufacture raw material. In this step, stacker and reclaimer will homogenize the material by using stacker technology.
- Clinker production: pre-heat is a necessary process before rotary kiln. The preheating and partial decomposition of the raw material are completed by the preheater, instead of the partial function of the rotary kiln, the length of the kiln is shortened, 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 the hot gas discharged from the kiln, the contact area of the gas material is increased, the heat transfer speed is fast, and the heat exchange efficiency is high, thereby improving the production efficiency of the kiln system and reducing the heat consumption of the clinker. The raw materials are preheated and pre-composed at the cement preheater. Next, all raw materials are sent into the rotary kiln to make a cement clinker. Dryer and clinker cooler are all used in this section.
- Finished cement: add some gypsum, admixture or additive into cement clinker, and using cement mill grinding cement clinker into finished cement. The finished cement can be stored in the cement silo or packed into bags. Cement silo and packing machine are common equipment used in this step.
What’s the function of every part of the cement production line? As a cement plant manufacturer with rich experience, AGICO Cement analyzes all cement plant equipment and helps you find the answer.
Cement crusher
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
Cement mill is another necessary cement plant 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
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
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 plant equipment. Except for the cement plant 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, cement plant upgrading also provides single cement plant equipment with high quality and competitive price, welcome to contact!
