YGM Raymond Mill
Product Introduction
YGM Raymond Mill(High Pressure Grinding Mill) | 30%-50% Higher Grinding Force-The Ideal Choice for Large-Scale Powder Processing of Medium-Hard Non-Metallic Minerals
YGM Raymond Mill (also known as High Pressure Grinding Mill) is a new-generation grinding equipment upgraded from the traditional Raymond mill. It is widely used for processing non-flammable, non-explosive materials with Mohs hardness ≤9.3 and moisture ≤6%, including limestone, calcite, marble, barite, gypsum, talc, kaolin, bentonite, dolomite, phosphate rock, manganese ore, feldspar, and more. With a high-pressure spring device installed on the roller assembly, the YGM series increases grinding force by 30%-50% compared to traditional Raymond mills, significantly improving grinding efficiency and achieving finer finished product fineness (80-600 mesh, up to 800 mesh for some materials).
Compared to traditional Raymond mills, the YGM High Pressure Mill offers higher grinding force, finer finished product, higher output, and lower energy consumption, making it especially suitable for processing medium-hard materials with Mohs hardness 5-9.3. The equipment is equipped with a PLC control system for one-touch start/stop, greatly enhancing automation.
We offer custom solutions ranging from single units to complete production lines, with products exported to over 50 countries and regions including the US, Russia, India, Vietnam, Indonesia, Egypt, and Brazil.
The YGM Raymond Mill is widely used for the following materials and industries:
| Material Type | Typical Materials | Hardness | Fineness | Industry Application |
|---|---|---|---|---|
| Carbonates | Limestone, calcite, marble, dolomite | ≤5 | 100-600 mesh | Building materials, paints, plastics, feed additives |
| Sulfates | Barite, gypsum, anhydrite | ≤4 | 200-400 mesh | Oil drilling weighting agent, building materials, molds |
| Silicates | Talc, kaolin, bentonite, mica | ≤4 | 200-600 mesh | Paper, ceramics, rubber, paints, cosmetics |
| Phosphates | Phosphate rock | ≤5 | 100-200 mesh | Phosphate fertilizer production |
| Oxides | Manganese ore, iron ore, chrome ore, molybdenum ore | ≤7 | 100-200 mesh | Metallurgy, mineral processing |
| Other Non-Metallic | Silicon carbide, corundum, zircon sand | ≤9.3 | 200-400 mesh | Refractories, abrasives |
Product Features

High Efficiency & Energy Saving
Output increased by 15%-30% and energy consumption reduced by 10%-20% at the same fineness compared to traditional Raymond mills, significantly lowering production costs per ton
Uniform & Adjustable Fineness
Fineness adjustable from 80-600 mesh, narrow particle size distribution, minimal over-grinding, meeting various high-end industry requirements
High One-Pass Yield & PLC Automatic Control
Closed-circuit system promptly separates qualified powder; coarse returns for regrinding, preventing over-grinding and increasing output, Standard PLC fully automatic control system, one-touch start/stop, real-time monitoring of current, temperature, vibration, and other parameters for automated production
Compact Structure, Small Footprint, Turnkey Solution
Vertical layout occupies only 1/3-1/2 of a ball mill's floor space, low civil cost, easy installation, Complete process solution from crushing, grinding, classification, collection to packaging
Environmentally Friendly, Dust-Free
Fully sealed negative pressure operation with pulse baghouse filter, dust emission <20mg/Nm³, meeting domestic and international environmental standards
Wear-Resistant & Durable
Grinding rollers and rings made of high-manganese or Ni-hard alloy, service life 10,000-15,000 hours; critical parts wear-treated
Strong Adaptability
Can process over 80 non-metallic minerals, from soft to medium-hard materials
Working Principle
The working principle of the YGM High Pressure Raymond Mill is based on the combined effect of centrifugal force and high-pressure springs:
1. Feeding
Material is crushed to ≤30mm, lifted by a bucket elevator into a raw material silo, and uniformly fed into the grinding chamber by an electromagnetic vibrating feeder.
2. High-Pressure Grinding
Under the dual action of centrifugal force and high-pressure springs, the grinding rollers press against the grinding ring with significantly higher force than traditional Raymond mills. Material scooped by shovel blades is thrown between the rollers and the ring, where it is crushed and ground into fine powder.
3. Classification
The ground powder is carried by airflow to the high-efficiency classifier. By adjusting the classifier rotor speed, final fineness is controlled. Qualified powder passes to the collection system, while coarse powder returns for regrinding in a closed circuit.
4. Collection & Dust Removal
Qualified fine powder enters a pulse baghouse filter, where it is collected by filter bags and conveyed to the finished product silo. The entire system operates under negative pressure for dust-free operation. The PLC control system monitors equipment status in real time for automated operation.
