There are two types of ball mill (also called cement mill) plant process: closed-circuit system and open circuit system. We use the new type closed-circuit system as the standard because it is more energy-efficient and can grind different types of cement.Cement grinding mill plant includes cement roller press, cement mill, cement seperator, dust collector, conveyor and other cement equipment.
1.In the roller press cement pre-grinding part, the fine power ground by roller will be sent to ball mill for further grinding. In a closed-circuit system, coarse particles are separated from finer product and return to ball mill for further grinding, making over-grinding unnecessary.
2.Cement ball mill is to grind and mix clinker with other aditives such as gypsum, slag, flyash etc. The cement mill is a big consumer of electricity, so in order to reduce power consumption, it is a good option to install roller press to reduce the particle size of the material before entering the ball mills.
3.The essential equipment of this closed-circuit grinding system is a cement classifier, also known as a cement separator. It is to select the required cement powder in time and send the much coarse cement powder back to the grinding mill for regrinding, making sure the uniform particle size.
4.Dust collector is to collect raw powder or finished cement. It is high dust removal efficiency and good sealing effect, improving working conditions and preventing air pollution.
5.The final cement packing could use cement packaging machine or build a finished product bin for the bulk system of cement tankers.
About Cement Mill Plant
Cement is a powdery hydraulic inorganic cementing material. After adding water and stirring, it becomes a slurry that could harden in the air or in water and bond sand, stone and other materials firmly together. Cement is widely used in civil engineering, water conservancy, national defense and other projects as an important cementing material. Clinker with appropriate gypsum, mixed material are grind into cement, this is known as cement grinding plant.
Ball mill is a traditional and widely used type in cement mills. It consists of a rotating cylinder filled with grinding media (usually steel balls). As the cylinder rotates, the balls cascade and grind the cement clinker and other additives. Cement grinding plant is an individual step in the cement production line. The new-type cement grinding plant adopt pre-grinding technology. It not only reduce the particles of feeding materials, but also help to produce cracks and flaws inside the particles, which largely increase the production capacity of cement mill and reduce the energy consumption too.
