HSS magnetic bearing turbo blowers and turbo compressors is an efficient, energy-saving and environmentally friendly equipment, which is widely used in cement production links such as material transportation, air supply, ventilation, powder homogenization and pneumatic conveying system. It has the advantages of low noise, no lubrication and simple maintenance.

Raw Meal Grinding System

Material Conveying: During the raw meal grinding process in cement plants, raw materials such as limestone and clay need to be crushed and ground into a fine powder. Magnetic bearing turbo blowers and turbo compressors can power the pneumatic conveying system, transporting the ground raw meal from the mill to the raw meal silo. Compared to traditional roots blowers, magnetic bearing turbo blowers and turbo compressors are more efficient and energy-efficient, reducing energy consumption during the conveying process and improving production efficiency.

System Ventilation: Raw material grinding systems require good ventilation during operation to ensure effective grinding and stable system operation. Magnetic bearing turbo blowers and turbo compressors provide the right amount of ventilation for the system, promptly discharging moisture and fines from the mill to prevent material blockage and condensation. They also regulate the temperature and pressure within the mill to optimize the grinding process.

Cement Kiln Calcination System

Combustion Air Supply: Cement kilns are the core equipment of cement plants. During the cement clinker calcination process, a large amount of combustion air is required to ensure sufficient combustion of the fuel and provide sufficient heat for the calcination reaction. Magnetic bearing turbo blowers and turbo compressors can precisely control the supply of combustion air. Based on the combustion conditions within the kiln and production needs, they can flexibly adjust air flow and pressure, improving combustion efficiency and reducing energy consumption. They also help stabilize the temperature and atmosphere within the kiln, ensuring the quality of the cement clinker.

Tertiary Air Supply: In the new dry-process cement production technology, tertiary air ducts are usually set up to introduce part of the hot air from the kiln-tail preheater system into the decomposition furnace, providing sufficient oxygen and heat for fuel combustion and calcium carbonate decomposition within the decomposition furnace. Magnetic bearing turbo blowers and turbo compressors can serve as tertiary air supply equipment, providing stable and efficient hot air to the precalciner, optimizing the combustion and decomposition processes within the precalciner and improving cement production yield and quality.

Cement Grinding System

Mill Ventilation: To improve grinding efficiency during cement grinding, fine powder and hot air must be promptly discharged to prevent over-grinding. Magnetic bearing turbo blowers and turbo compressors provide the appropriate ventilation for the cement mill, allowing the material to be promptly transported to the classifier for classification, thereby increasing the grinding system's output and the specific surface area of the cement.

Air for Classifier: The classifier is a crucial piece of equipment in the cement grinding system. Its function is to classify the ground cement particles according to different particle sizes, separating the finished cement that meets the requirements and returning the unqualified coarse powder to the mill for further grinding. Magnetic bearing turbo blowers and turbo compressors provide the required airflow for the classifier. By adjusting the air volume and pressure, the classifier's efficiency and product quality can be precisely controlled, ensuring the proper particle size distribution of the cement.

Pneumatic Conveying System

Cement Conveying: Cement plants often use pneumatic conveying to transport finished cement from the cement storage to the packaging plant or bulk trucks. Magnetic bearing turbo blowers and turbo compressors, as the power source for pneumatic conveying systems, provide a stable air supply, ensuring smooth cement transportation. Its high efficiency and energy-saving properties reduce energy consumption and operating costs during the conveying process, while also minimizing the risk of pipeline wear and blockage.

Conveying Fly Ash and Other Materials: In addition to cement transportation, cement plants also need to transport and store auxiliary materials such as fly ash and slag powder. Magnetic bearing turbo blowers and turbo compressors can also be used in pneumatic conveying systems for these materials. Based on the characteristics of the different materials and the required conveying distance, the appropriate Magnetic bearing turbo blowers and turbo compressors model and parameters can be selected to achieve efficient and reliable material conveying.
