Description

Technical Field

[0001] This utility model relates to the field of coal powder grinding technology, specifically to a steel ball removal device for a high-efficiency grinding mill. Background Technology

[0002] Coal powder is required for thermal power generation. This coal powder is usually made by grinding coal lumps into powder using a grinder. Most existing coal powder grinders use steel balls to grind the coal lumps. The steel balls are thrown up by rotation, and the coal lumps are ground into powder by gravity and mutual collision. As grinding continues, the steel balls in the coal powder grinder will be worn down. Therefore, after grinding a certain amount of coal lumps, new steel balls need to be added to the grinder to ensure grinding efficiency. However, since the condition of the steel balls in the coal powder grinder is uncertain, the grinding efficiency will vary even after adding new steel balls. Sometimes, the size of the ground coal may not meet the requirements, requiring secondary grinding, which is very time-consuming and costly. Therefore, it is particularly important to design a device that can remove the steel balls from the grinder to solve the above problems. Summary of the Invention

[0003] To solve the above problems, this utility model designs a steel ball removal device for a high-efficiency grinder. By using an electromagnet located at the bottom right end of the rocker arm, the steel ball can be attracted and held inside the grinding drum, and then removed along the inlet and outlet of the rocker arm. This allows for a clear understanding of the wear and tear of the steel balls inside the grinding drum, ensuring that the grinding efficiency and quality of the grinder meet the requirements after adding new steel balls.

[0004] To solve the above-mentioned technical problems, this utility model provides a steel ball removal device for a high-efficiency grinding machine, characterized in that it includes a grinding drum, support seats, guide seats, a discharge cylinder, a suction pipe, a rocker arm, a back-and-forth swinging mechanism, a support plate, and an electromagnet.
