Raymond Mill
Designed for mineral powder production, the Raymond mill processes non-flammable and non-explosive materials such as limestone, calcite, barite, potash feldspar and marble. It is suitable for powder preparation in building materials, mineral processing and chemical applications. Model selection depends on the feed material, required fineness and production capacity.
- Capacity: 0.3–15 t/h, depending on model and application
- Max. Feed Size: 10–35 mm, depending on model
- Product Fineness: 80–325 mesh; up to 400 mesh for selected models
- Feed Moisture: Below 6%
Key Features
Compact Vertical Layout
The vertical arrangement brings the main grinding components into a compact unit that can be incorporated into a mineral powder production system.
Flexible Powder Fineness
Different powder fineness requirements can be accommodated within the selected model’s operating range. The required fineness should be confirmed for each material and application.
Multiple Roller Configurations
Models with three to six grinding rollers are available, providing a range of configurations for different material processing and production requirements.
Versatile Mineral Processing
Suitable for processing limestone, calcite, barite, potash feldspar and other suitable non-flammable, non-explosive minerals into powder for industrial applications.
Design & Working Principle

- Prepared material is fed into the Raymond mill at a controlled rate and ground between the rollers and grinding ring.
- Airflow carries the ground powder to the classifier. Coarse particles return to the grinding chamber, while sufficiently fine particles pass through with the air.
- Fine powder enters the cyclone collector, where it is separated from the air and discharged for storage or packing.

Note: Specifications are manufacturer-provided reference values. Capacity depends on the material, feed size, moisture and required product fineness. The maximum capacity and finest product size are not necessarily achieved at the same operating condition. Main motor power excludes the fan, classifier and other auxiliary equipment. Final specifications are subject to the confirmed technical proposal.
