• High-Pressure Grinding: Through the implementation of improved pressure mechanisms (such as high-pressure springs or hydraulic systems), the crushing force exerted by the grinding rollers against the grinding ring has been significantly increased, resulting in a marked improvement in grinding efficiency compared to traditional equipment.
• Wide Fineness Range: The fineness of the finished product is typically adjustable within a range of 80 to 425 mesh; certain advanced models, utilizing multi-stage classifiers, are capable of achieving even finer particle sizes.
• Energy-Efficient and Eco-Friendly: The air duct design and dust collection system have been optimized to ensure smoother operation and lower noise levels, while dust emissions fully comply with environmental protection standards.
• High Stability: Critical components—such as the main unit base and frame—have undergone structural reinforcement, making the machine highly suitable for continuous, long-duration operation.
Primarily suitable for non-metallic mineral products with a Mohs hardness of 7 or less and a moisture content of 6% or less.
Examples include:
• Construction & Chemicals: Limestone, Calcite, Calcium Carbonate, Dolomite, Barite, Talc.
• Ceramics & Refractories: Quartz, Feldspar, Kaolin (Ceramic Clay), Bentonite.
• Others: Coal Gangue, Slag, etc.
YGMX Grinding Mill, Ultrafine High-Pressure Mill
Energy-Efficient High-Pressure Mill
Eco-Friendly Medium-Speed Mill
80–600 Mesh Ultrafine Powder Processing Equipment
Compared to the standard YGM series, the most significant improvement in the YGMX series lies in its high-pressure spring or hydraulic boosting mechanism.
• Physical Principle: Under the same power input, the application of lever mechanics or hydraulic principles increases the crushing force exerted by the grinding rollers against the grinding ring by approximately 800 to 1200 kg.
• Direct Result: This enhancement ensures high production output even when processing materials of slightly higher hardness (such as quartz), while simultaneously yielding a finished product with a more uniform particle size distribution.
The 600-mesh fineness level you mentioned represents a critical performance benchmark. Traditional Raymond mills (YGM)typically have a fineness limit of 325–425 mesh; however, the YGMX achieves a breakthrough in fineness through the following mechanisms:
• High-Efficiency Air Classifier: It employs a cage-type air classifier (grader) equipped with variable frequency speed control, enabling more precise separation of ultrafine powders and minimizing the contamination of the final product by coarse particles.
• Optimized Internal Circulation System: This reduces the ineffective accumulation of material within the grinding chamber and accelerates the rate at which material is conveyed into the classification zone.
Given its capability to achieve a fineness of up to 600 mesh, the YGMX is ideally suited for the following high-value-added industries:
• Paper & Coatings: Used for processing ultrafine heavy calcium carbonate with high whiteness.
• Plastics & Rubber: Serves as a high-performance inorganic mineral filler.
• Desulfurization & Environmental Protection: Produces the ultrafine limestone powder required for flue gas desulfurization in power plants.
Utilizing a high-pressure spring/hydraulic boosting design, the grinding pressure is increased by 800–1200 kg, resulting in a 10%–20% increase in output for the same power input.
The fineness of the finished product is adjustable within the range of 80–600 mesh (0.028 mm); equipped with a variable-frequency classifier, the system ensures an optimal particle size distribution.
A thickened base combined with a vibration-damping design effectively reduces high-frequency vibrations and noise, thereby extending the service life of the equipment.
A fully sealed, negative-pressure circulation system paired with a pulse dust collector achieves a dust removal efficiency of over 99%, meeting rigorous environmental protection standards.
Key Differences in Operating Principles Between the YGMX and the Traditional YGM Series:
1. Enhanced Grinding Force: The YGMX incorporates high-pressure springs into its grinding roller suspension assembly, increasing the crushing pressure exerted on the grinding ring by approximately 1.2 times compared to a YGM mill of equivalent power output. This ensures that even materials with slightly higher hardness can be easily ground to the desired fineness.
2. Superior Classification Precision: The YGMX is typically equipped with a high-precision, variable-frequency cage-type air classifier, whereas traditional Raymond mills predominantly utilize blade-type classifiers. This advanced classification technology serves as the technical guarantee for the YGMX's ability to consistently produce ultrafine powders with a fineness of 600 mesh.
3. Reduced Airflow Resistance: The improved air duct design minimizes airflow resistance, resulting in higher material conveying efficiency and a reduction in noise generated by air friction.
In Summary: The operating principle of the YGMX can be likened to that of a colossal grinding machine equipped with "turbo-boosting" and "intelligent sorting" capabilities, enabling it to produce higher-quality powders while consuming less energy.
