Products Description
Bellian Raymond Mill is the most classic and widely used grinding equipment in the world, specially designed for producing 80-400 mesh powder from various non-metallic minerals. It has been continuously improved and upgraded for more than 100 years, with mature technology, stable performance and low investment cost. Our Raymond Mill adopts advanced structure design, which increases the grinding efficiency by 20% compared with traditional models, and reduces energy consumption by 15%. It is the first choice for small and medium-sized powder production lines.
Working Principle
The Raymond Mill mainly consists of main frame, grinding roller, grinding ring, blower, analyzer, pipeline and dust collector. When the machine works, the materials are fed into the grinding chamber from the hopper. The grinding rollers rotate around the central axis and also rotate around the grinding ring under the action of centrifugal force. The materials are crushed and ground between the grinding rollers and grinding ring. The ground powder is blown up by the blower and classified by the analyzer. The qualified powder enters the cyclone collector and is discharged, while the unqualified powder falls back to the grinding chamber for re-grinding.
Performance Features
Three-dimensional structure design, small floor area, complete set of equipment, can form an independent production system from raw material crushing to finished powder packaging
High grinding efficiency, the same output requires only 1/3 of the energy consumption of ball mill, greatly reducing production cost
Wear-resistant parts are made of high manganese steel, which has strong wear resistance and long service life, reducing the number of shutdown maintenance
Equipped with high-efficiency pulse dust collector, the dust emission concentration is lower than 30mg/m³, meeting international environmental protection standards
The fineness of finished products can be adjusted freely between 80-400 mesh, and the product quality is stable and uniform
Simple operation and maintenance, one person can operate multiple machines, reducing labor cost

Application Scenarios
Widely used in mining, metallurgy, chemical industry, building materials, medicine, food and other industries. Suitable for grinding various non-flammable and explosive materials with Mohs hardness below 7 and moisture content below 6%, such as limestone, calcite, barite, gypsum, talc, feldspar, marble, dolomite, kaolin, bentonite, etc.
FAQ
What is the difference between 3R, 4R, 5R and 6R Raymond Mill?
The number before "R" represents the number of grinding rollers. The more grinding rollers, the larger the grinding area, the higher the output and the higher the power. 3R and 4R models are suitable for small and medium-sized production lines, while 5R and 6R models are suitable for large-scale production lines. We will recommend the most suitable model according to your required output and material properties.
Can Raymond Mill grind hard materials like granite?
Raymond Mill is suitable for grinding materials with Mohs hardness below 7. For materials with Mohs hardness above 7 such as granite and basalt, we recommend you choose our YGM High Pressure Suspension Mill or Vertical Roller Mill, which have stronger grinding force and better wear resistance.
What is the service life of wearing parts?
The service life of grinding rollers and grinding rings depends on the hardness of the materials being ground. For soft materials like limestone, the service life is about 6-12 months; for medium-hard materials like barite, the service life is about 3-6 months. We provide all kinds of wearing parts with preferential prices and fast delivery.
Do you provide turnkey solutions for Raymond Mill production lines?
Yes, we can provide complete turnkey solutions including raw material crushing, conveying, grinding, classification, dust collection and packaging. From design, manufacturing to installation, commissioning and operator training, we provide one-stop service to ensure your production line runs smoothly.
