The LM vertical mill boasts an 85%-95% yield rate, making it suitable for large-scale production. The LMX ultrafine mill offers excellent purity above 800 mesh. Raymond mills offer excellent cost-effectiveness in the medium fineness range. Ultrafine vertical mills offer industry-leading purity. When selecting a model, consider the balance between fineness, production capacity, and purity. We recommend customized solutions.

LM vertical grinding mill

Yield rate: High. The system integrates crushing, grinding, and classification. The material can reach the target fineness in one pass, reducing repeated grinding. The yield rate is usually 85%-95%.

Purity maintenance:

The grinding roller and grinding disc are made of wear-resistant material, which reduces wear and reduces the mixing of metal impurities.

The fully enclosed system is equipped with dust removal to avoid external pollution, but the purity of coarse powder processing is slightly lower than that of ultrafine equipment.

Advantages: suitable for large-scale production, wide adaptability to raw materials, and stable yield rate.

Disadvantages: The higher the fineness, the lower the yield. The purity is better below 600 mesh.

LMX ultrafine vertical grinding equipment

● Yield rate: medium to high. The secondary grading system can accurately control the fineness, with a yield rate of approximately 80%-90% (depending on the target fineness).

● Purity maintenance:

○ High grading accuracy, which can effectively separate qualified powder from unqualified powder and avoid over-grinding.

○ Full negative pressure operation reduces dust overflow and is equipped with a high-efficiency dust removal system to maintain excellent purity.

○ Fewer wearing parts, less impurities mixed in, suitable for high purity requirements.

● Advantages: The yield rate in the ultrafine powder field is stable, and it is especially suitable for processing fine powders above 800 mesh.

● Disadvantages: Production capacity decreases at finer mesh sizes, but purity compensates for some of the efficiency loss.

Raymond mill

● Yield rate: Medium. The yield rate of traditional Raymond mills is about 70%-85%, while optimized models (such as those with efficient grading systems) can reach 90%.

● Purity maintenance:

○ The grinding roller and grinding ring wear quickly, which may introduce a small amount of metal impurities, but this can be controlled by regular replacement.

○ The cyclone collector has a higher classification efficiency and the finished product has a uniform particle size, but the purity of the fine powder is slightly affected.

● Advantages: The yield rate in the medium fineness range (80-600 mesh) is stable and the equipment cost is low.

● Disadvantages: The classification efficiency decreases at high fineness, and secondary classification equipment is required to improve the purity.

Ultrafine vertical grinding equipment

● Yield rate: medium to high. Secondary classification and efficient powder selection system keep the yield rate stable at 80%-90%.

● Purity maintenance:

○ The classification accuracy is extremely high, which can separate the coarse particles in the ultrafine powder to ensure uniform particle size.

○ Wear-resistant material and sealing structure reduce wear and external pollution, and have excellent purity.

○ Suitable for processing high value-added products (such as pharmaceutical grade talc).

● Advantages: The purity of ultrafine powder leads the industry and is suitable for high-requirement fields.

● Disadvantages: Equipment investment is high and the yield rate is greatly affected by the fineness target.

In summary, equipment selection requires a balance between yield and purity based on target fineness, production capacity requirements, and product application. Ultrafine grinding equipment achieves higher purity through grading and sealing designs, while traditional equipment offers a higher yield advantage in coarse powder processing. It is recommended to contact a professional manufacturer for targeted testing and customized solutions to ensure that equipment performance matches actual needs.
