YGM Grinding Mill
The YGM high-pressure grinding mill is primarily suitable for grinding mineral materials in metallurgy, building materials, chemicals, and mining. YGM grinding mill can grind various non-flammable and explosive mineral materials with a Mohs hardness of 9.3 or less and a humidity of 6%, such as quartz, feldspar, calcite, talc, manganese ore, iron ore, copper ore, phosphate rock, fly ash, bituminous coal, coal gangue, shale, purple sandstone, green muddy rock, shale rock, basalt, and so on.
The YGM grinding mill is the culmination of “high-pressure spring + suspension roller mill” technology. It is an upgraded version of the traditional Raymond mill, offering high production capacity, high fineness, and low energy consumption. It has become the mainstream equipment for preparing non-metallic mineral powders with mesh sizes of 80-425.

What is a YGM grinding mill?
YGM Grinding Mill Machine
The YGM grinding mill is a high-pressure upgrade of the traditional R-type Raymond mill. By adding a 1000–1500 kg high-pressure spring system to the grinding roller assembly, the rolling pressure between the rollers and the rings is increased by 1.2–1.4 times, significantly improving output and fineness without changing motor power.

YGM grinding mill structural features
1. The YGM grinding mill is a vertical structure featuring a small footprint and high completeness. From bulk material to crushing, to finished powder and packaging, it can form a self-contained production system.
2. The YGM grinding mill produces a variety of powders with uniform fineness, achieving 99% of the required fineness, meaning 99% of the sieve passes. This is a feat unmatched by other grinding equipment.
3. The mill’s main transmission system utilizes a sealed gearbox and pulleys, ensuring smooth and reliable operation. Key components are constructed of high-quality steel, making the entire machine durable, stable, and reliable.
4. The mill’s electrical system utilizes centralized control, featuring advanced and rationally selected components. This allows for virtually unmanned operation within the grinding vehicle. The vibrating feeder is compact and lightweight, delivering uniform feed, easy adjustment, energy-saving, and convenient operation and maintenance.
YGM Mill Structural Features
The YGM mill is fully equipped with a hammer crusher, bucket elevator, storage silo, vibrating feeder, micro-powder mill, variable frequency classifier, dual cyclone collector, pulse dust removal system, high-pressure fan, air compressor, and electrical control system.
Main Unit
The grinding roller assembly is suspended on a plum blossom frame via a cross-arm shaft. A 1000–1500 kg high-pressure spring is installed at the outer end, forming a three-point floating pressure system (spring-grinding roller-grinding ring). The spring length can be adjusted after wear to maintain a constant grinding force.
Grading System
Cage-type or turbine-type analyzer with variable frequency drive and stepless speed regulation, allowing for adjustable mesh sizes from 80–1000. Aerodynamically optimized blades achieve a grading efficiency of ≥90%.
Airflow and Dust Collection
A high-pressure centrifugal fan and curved air duct provide low system resistance. A cyclone and pulse bag filter system provide two-stage dust collection, ensuring dust emissions of ≤10 mg/Nm³, meeting environmental standards.
Sealing and Noise Reduction
The grinding roller assembly utilizes overlapping multi-stage sealing to prevent powder leakage. Composite vibration damping pads are installed on the main unit base and fan, ensuring overall noise levels of ≤85 dB(A).
Modular auxiliary configuration
Optional jaw crusher, hammer crusher, elevator, storage silo, variable frequency feeder, and electrical control cabinet can be configured according to process requirements, enabling one-touch start and stop and remote monitoring.
Six key features of the YGM grinding mill
■ Compared to other mills under the same power conditions, the YGM high-pressure grinding mill increases output by 10-20%. The high-pressure springs increase the grinding roller’s crushing force by 800-1200 kg.
■ Mineral materials with a Mohs hardness of less than 9.3 can be processed and crushed.
■ A wide range of finished product particle sizes is available, with the coarsest particle size reaching 0.613 mm (30 mesh) and the typical particle size reaching 0.033 mm (425 mesh). A small number of materials can reach as fine as 0.013 mm (1000 mesh).
■ Dust removal fully meets national dust emission standards.
■ The analyzer is easy to adjust.
■ The grinding unit utilizes overlapping multi-stage seals for excellent sealing performance.
