Edge Turning Gearboxes for Coal Mills

Precise torque adaptation: The torque range of this product series is reasonably distributed, which can accurately provide suitable torque output according to the edge-driven mills of different specifications and production requirements.

Structural optimization and upgrading: With the help of finite element analysis technology, the structure of key parts is optimized in depth. By simulating and analyzing the parts under various stress conditions, redundancies are removed to make the structure more compact.

Excellent tooth shape optimization: unique gear trimming technology is adopted to precisely adjust the shape of tooth profile and tooth direction. During the gear meshing process, the contact state is effectively improved, so that the load is evenly distributed, reducing shocks and vibrations, thus realizing a smoother transmission and significantly reducing the operating noise.

flexible design options: two design options are available, including and without oil sump, to fully meet the individual needs of different users and specific working conditions. The oiled sump design is convenient for use in some relatively simple lubrication system requirements and high maintenance convenience; the oil-free sump design can be used with more complex centralized lubrication system, suitable for large-scale, high-load production equipment, users can choose flexibly according to their own actual situation.

Convenient external components: The external components are designed to be simple and reliable, focusing on the convenience of on-site operation and maintenance. The layout of each component is reasonable and the connection method is convenient, which is easy for operators to carry out daily inspection, maintenance as well as troubleshooting and repair.

Diversified attachment configuration: Equipped with a variety of attachments to choose from, users can customize according to specific application scenarios and process requirements. These accessories can further expand the functions of the gearbox, such as adding cooling devices to adapt to high-temperature environments, installing monitoring sensors to realize intelligent operation and maintenance, etc., which meets different requirements while maintaining a high cost-effective price, and provides users with more value options.

 

Moderate speed ratio range: The speed ratio range is set between 4 and 7.1, which can be flexibly selected according to the different process requirements of edge-driven mills such as cement mills and coal mills. Through accurate matching of speed ratios, the rotational speed and grinding effect of the mill can be effectively controlled to ensure that the materials are fully crushed and ground in the mill to improve product quality and production efficiency.

Wide power coverage: Rated power ranges from 120 - 7,900 (kW), a wide power range that allows it to be adapted to all sizes of cement mills and coal mills. From small-scale processing plants to the main production equipment of large cement manufacturers, we can find suitable power gearboxes to match, providing stable and reliable Power transmission for production lines of different capacities.

 

Edge-driven mill gearboxes specifically applied to cement mills and coal mills. In the process of cement production, it undertakes the important task of pulverizing and grinding cement raw materials, such as limestone, clay, iron ore, etc., to process them into cement clinker or finished cement that meets the production standards. In the field of coal milling, it is used to grind raw coal to achieve specific particle size requirements to meet the fuel supply or raw material processing needs of power plants, coal chemical industry, etc. It is an indispensable key transmission equipment in cement and coal milling industry.

 

Before installation, the model and specification of the gearbox should be carefully checked for suitability with the mill equipment, and ensure that the installation foundation is firm, level and in accordance with the design requirements, so as to avoid vibration and displacement during operation due to the poor foundation, which will affect the life of the equipment and the quality of production.

Before the first operation, make sure to clean the inside of the gear box, check the installation and lubrication status of the gears, bearings and other key components, fill the lubricant according to the specified oil level and oil requirements, and at the same time fasten the external connecting parts to ensure that there is no abnormality in the equipment before starting.

In the operation process, we should regularly monitor the oil temperature, oil pressure, vibration, noise and other key parameters of the gear box, and establish a perfect operation record file. If abnormal fluctuation or exceeding of parameters is found, the machine should be shut down immediately for checking, troubleshooting the cause of failure and repairing it in time, and it is strictly prohibited to run the equipment with faults so as not to cause greater losses.

Strictly in accordance with the requirements of the equipment maintenance manual, regular maintenance of the gear box. This includes replacing lubricating oil and filters, checking the wear of gears and bearings, cleaning and anticorrosion treatment of external components. For gearboxes with oil sump design, pay attention to checking the sealing performance of the oil sump to prevent oil leakage; for gearboxes without oil sump design, ensure the normal operation and maintenance of the external lubrication system.
