Which kind of mill is better for a limestone crusher with a daily output of 500 tons?

For a limestone crusher with a daily output of 500 tons, a large-scale milling equipment is required to process the limestone into powder. Here are two types of mills that are suitable for processing limestone:

1. Raymond mill: Raymond mill is a commonly used milling equipment for processing limestone. It has a small footprint, low investment cost, and high grinding efficiency. The finished product has a uniform particle size and good quality. However, the production capacity of Raymond mill is relatively low, and it may not be suitable for processing large volumes of limestone.

2. Vertical roller mill: Vertical roller mill is a modern milling equipment that integrates crushing, grinding, drying, and grading functions. It has a large production capacity, high grinding efficiency, and low energy consumption. The finished product has a uniform particle size and good quality. However, the initial investment cost of vertical roller mill is relatively high, and it requires a larger operating space.

Here is a table summarizing the characteristics of Raymond mill and vertical roller mill:

| Milling Equipment | Characteristics |

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

| Raymond mill | - Small footprint<br>- Low investment cost<br>- High grinding efficiency<br>- Suitable for processing small volumes of limestone |

| Vertical roller mill | - Large production capacity<br>- High grinding efficiency<br>- Low energy consumption<br>- Suitable for processing large volumes of limestone<br>- Requires a larger operating space |

Please note that these characteristics are only for reference and may vary depending on the specific situation. It is recommended to consult with a qualified technician or manufacturer for a proper diagnosis and repair.
