Description

Technical Field

[0001] This utility model relates to the field of mineral processing ball mill technology, and in particular to a semi-autogenous gear air-cooling device. Background Technology

[0002] During the high-temperature period in summer, the temperature of the semi-autogenous grinding pinion in the mineral processing workshop can reach as high as 95 degrees Celsius, which has a significant impact on gear lubrication and lifespan. Because the semi-autogenous grinding gear uses an open spray lubrication method, it mainly relies on intermittent oil spray followed by air cooling for heat dissipation. Since the oil spraying and air cooling cycle is more than 20 minutes, and each air blowing time is less than 1 minute, it is not effective in cooling the gear operating environment during high-temperature periods.

[0003] Therefore, it is necessary to provide a semi-self-grinding gear air-cooling device to solve the above-mentioned technical problems. Utility Model Content
