What is a limestone grinding mill?

 The main component of limestone is calcium carbonate, which is an indispensable raw material for industries such as cement and steel. To make limestone play a role in various fields, a powder mill is essential. Different types of powder mills can process limestone into powders with different finenesses to meet diverse needs. Common limestone grinding mills include Raymond powder mills, ultra-fine powder mills, vertical powder mills, etc.

Types of limestone grinding mills

Raymond Powder Mill

Fully known as a suspension roller powder mill, it has a low investment cost, is easy to operate and maintain, and has low energy consumption, making it suitable for small and medium-sized enterprises. The production capacity for small and medium-sized enterprises is 1 - 25 tons per hour, and it is often used for the medium and small-scale powder processing of limestone in industries such as mines and building materials with a fineness of 80 - 325 mesh.

Ultra-fine Powder Mill

The pressure device in the main grinding chamber of the machine increases the grinding pressure by 20% - 30%, and the production capacity is increased by 10% - 30%. It can process materials with higher hardness, has a wide range of applications, and the fineness of the finished product can reach about 1000 mesh with adjustable fineness, which has an advantage in ceramic raw material processing.

Vertical Powder Mill

It is large-scale and has a high production capacity, with 5 - 300 tons per hour. It integrates crushing, grinding, classification, and drying, has low power consumption, but is complex to maintain and has a high initial investment. It is suitable for large-scale production by large enterprises, such as in cement raw material production.

Other limestone grinding mills

Ball Mill + Classifier

It produces ultra-fine powder through wet or dry grinding in combination with a classifier. It has high energy consumption, but the fineness adjustment is flexible, and the fineness of the finished product can be adjusted from 325 - 2500 mesh, which is suitable for the production of high-value-added products, such as in the fine chemical industry.

Selection Guide for limestone grinding mills

For large-scale production, a vertical mill should be given priority. For small-scale enterprises or those with flexible needs, the Raymond powder mill is more economical and practical. If the material humidity is high (＞5%), a drying system is required. If there are iron impurities, iron removal is necessary. For high environmental protection requirements, dust removal equipment needs to be equipped.

Coarse Powder (80 - 325 Mesh)

The Raymond powder mill is suitable for small and medium-sized production capacity enterprises, and the ultra-fine powder mill has more advantages in processing high-hardness materials and increasing fineness.

Fine Powder (400 - 800 Mesh)

The vertical mill is suitable for large-scale production, and the ultra-fine powder mill meets the needs of medium-scale enterprises.

Ultra-fine Powder (above 800 Mesh)

The combination of ball mill + classifier has flexible fineness adjustment, and the ultra-fine powder mill has low energy consumption and a compact structure.

Summary

limestone grinding mills mainly include Raymond mills (for small and medium production capacity, economical), ultra-fine mills (with a fineness of thousands of mesh), vertical mills (for large-scale, high investment), and ball mill combinations (for ultra-fine with high energy consumption). When selecting, factors such as fineness, production capacity, material characteristics, and environmental protection requirements need to be considered. Cronus Powder Mill focuses on powder processing and is an excellent choice for limestone powder production.
