The difference between vertical and high pressure mill

Vertical mill and high pressure mill are two different types of grinding equipment used in various industries. Here are some differences between vertical mill and high pressure mill:

1. Grinding principle: Vertical mill is a grinding equipment that uses the grinding roller to directly crush the material on the grinding disc, while high pressure mill uses a grinding roller and a grinding ring to grind the material.

2. Grinding efficiency: Vertical mill has a higher grinding efficiency than high pressure mill, as it can grind materials with higher moisture content and larger feed size.

3. Energy consumption: High pressure mill consumes more energy than vertical mill due to its complex grinding process and high power consumption.

4. Application range: Vertical mill is suitable for grinding non-metallic minerals such as calcium carbonate, barite, calcite, talc, and kaolin. High pressure mill is suitable for grinding various non-flammable and explosive materials with Mohs hardness below 9.3 and humidity below 6%, such as quartz, feldspar, talc, calcite, limestone, and other materials.

Here is a table summarizing the differences between vertical mill and high pressure mill:

| Parameter | Vertical mill | High pressure mill |

|-----------|--------------|--------------------|

| Grinding principle | Grinding roller directly crushes the material on the grinding disc | Grinding roller and grinding ring grind the material |

| Grinding efficiency | Higher grinding efficiency | Lower grinding efficiency |

| Energy consumption | Lower energy consumption | Higher energy consumption |

| Application range | Suitable for grinding non-metallic minerals | Suitable for grinding various non-flammable and explosive materials |

Please note that these differences are only for reference and may vary depending on the specific situation. It is recommended to consult with a qualified engineer or industry expert for a proper analysis of the differences between vertical mill and high pressure mill.
