Raymond Mill
Raymond mill is widely used for grinding limestone, dolomite, barite, gypsum, calcite, marble and other non-metallic minerals with Mohs hardness below 9.3. It features stable performance, high grinding efficiency, adjustable fineness and low energy consumption for powder processing applications.
- Adjustable Powder Fineness – Finished size adjustable from 80-325 mesh
- Efficient Grinding Performance – Stable operation with low energy consumption
- Wide Material Application – Limestone, dolomite, barite, gypsum and marble
- Multiple Grinding Solutions – Raymond, high pressure and superfine mills
Tell us your material type, required fineness and production capacity. Our engineers can recommend a suitable grinding mill solution for your project.
Structural composition of Raymond Mill
The structure of the machine is mainly composed of main machine, analyzer, fan, finished cyclone separator, micro powder cyclone separator and air duct. The main engine is composed of frame, air inlet volute, blade, grinding roller, grinding ring and cover.
Working principle of Raymond Mill
After the material is ground, the fan blows the air into the main machine shell, blows up the powder, and sorts it through the analyzer placed above the grinding chamber. The material with too fine and too coarse falls into the grinding chamber for regrinding, and the material with the fineness conforming to the specification flows into the cyclone collector with the wind flow, and is discharged through the powder outlet after collection, which is the finished product. The air flow is returned to the fan by the return air pipe at the upper end of the large cyclone collector. The air path is circulating and flows under the negative pressure state. The air volume increase part of the circulation air path is discharged through the exhaust gas pipe between the fan and the host, and enters the small cyclone collector for purification.
