Introduction of large gear ring for ball mill:
Large gear ring for ball mill is one of the core components of the ball mill, responsible for transmitting the power of the motor to the drum, making it rotate stably, so as to grind ores, minerals and other materials efficiently. Large gear ring for ball mill is a sturdy and durable large circular gear, which precisely meshes with the pinion gear to make the ball mill run smoothly and grind efficiently during work.
Advantages of ball mill ring gear:
1. Due to the large shape and weight of ball mill ring gear, it requires a large furnace and related equipment. We have professional equipment to manufacture it.
2. Ball mill ring gear is used in various types of horizontal mills, rotary dryers and rotary kilns.
3. Ball mill ring gear adopts a variety of processing methods such as sand casting, investment casting, shell casting, etc., and we can also provide ball mill ring gear in different materials such as ductile iron, gray cast iron, carbon steel, alloy steel, etc.
Processing and advantages of steel casting girth gear：
1. Forging/casting: Steel casting girth gear can be manufactured by forging or casting. Forged gear rings have higher density and strength and are suitable for extreme working conditions, while cast gear rings can more flexibly meet complex design requirements. Both processes can make ball mill ring gear have excellent wear resistance and impact resistance, and improve service life.
2. Normalizing + tempering: Normalizing treatment can improve the uniformity of ball mill ring gear's structure and mechanical properties, while eliminating the internal stress generated during casting or forging, and reducing the risk of deformation and cracking. Tempering further improves the toughness of the material, allowing ball mill ring gear to remain stable during high-load operation and reduce the risk of fracture.
3. Quenching + tempering: The quenching process significantly improves the surface hardness of large gear ring for ball mill, enhancing its wear resistance and fatigue resistance, while tempering can reduce the brittleness generated during the quenching process, making large gear ring for ball mill both hard and wear-resistant, and has good impact resistance, suitable for long-term continuous operation of ball mills.
4. Finishing (gear grinding): Through the high-precision gear grinding process, the finish and meshing accuracy of large gear ring for ball mill are greatly improved, reducing friction loss, improving transmission efficiency, thereby reducing energy consumption and extending the life of the entire machine.
About us:
In terms of technology, we have introduced and adopted advanced casting technologies such as high-pressure injection molding, shell core making, and three-dimensional process design. In terms of casting equipment, we first introduced two detachable box-type FBOⅢ injection molding automatic production lines from Japan (box size: 605×505×200㎜), which can produce 120 sand molds per hour and 7,000 tons of castings per year. Later, we introduced a world-leading static pressure automatic production line (box size: 1000×800×350/300㎜), which can produce 90 sand molds per hour and 30,000 tons of castings per year, and the production scope has been broadened.
