YGM Raymond Mill

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).

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

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

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.
