1. Timely lubrication of ultrafine vertical mill and related equipment2. When using the ultrafine vertical mill, it is strictly forbidden to use metal ore to enter the main body to avoid damage to the grinding ring.3. When feeding the main unit, the feed should be even, too much may block the air passage and reduce the output.4. Precautions for air volume adjustment: The air volume is small and the fineness is high, but it should be noted that the air volume is too small, and the main air duct is easy to precipitate materials.5. According to the size of the material, soft and hard, water content, specific gravity, processing requirements, the analyzer should be properly adjusted. The working principle of ultrafine vertical mill equipment produced by our company is roughly the same.
