The application of grinding equipment in various fields is becoming more and more widespread. Raymond mill and vertical mill are two common grinding equipment. Let’s understand the difference between these two equipment.
- Working principle
Raymond mill is a kind of equipment that crushes materials by extrusion, impact, grinding and other methods. Its working principle is to use the rotation of the grinding ring and the grinding roller to extrude, impact and grind the material into fine powder. The vertical mill is a kind of equipment mainly for grinding. Its working principle is to use the rotation of the grinding disc and the grinding roller to make the material be squeezed, ground and sheared in the grinding area to obtain fine powder.

- Structural characteristics
The structure of the Raymond mill is relatively simple, mainly composed of the main machine, analyzer, fan and other parts. The structure of the vertical mill is relatively complex, mainly composed of the main machine, powder selector, conveying device and other parts.
- Production capacity
Since the Raymond mill crushes the material by extrusion, impact, grinding and other methods, its production capacity is relatively large, and it can generally reach several tons per hour. Vertical mill is mainly used for grinding, and its production capacity is relatively small, generally only hundreds of kilograms per hour.
- Scope of application
Raymond mill is suitable for processing materials with high hardness and low water content, such as limestone, gypsum, marble, etc. Vertical mill is suitable for processing materials with low hardness and high water content, such as coal powder, slag, etc.
- Price and maintenance cost
The price of Raymond mill is relatively low, and the maintenance cost is also low. The price of vertical mill is relatively high, and the maintenance cost is also high.
There are obvious differences between Raymond mill and vertical mill in structure, working principle, scope of application, production capacity, environmental pollution and maintenance cost. When choosing which equipment to use, it is necessary to make comprehensive considerations based on actual conditions.
