Mill
With the development of industry, grinding equipment is more and more widely used in various fields. Among them, Raymond mill and vertical mill are two common grinding equipment. This article will detail the differences between these two devices.
First, the working principle.
Raymond mill is a kind of equipment that crushes materials by extrusion, impact, grinding, etc. Its working principle is to use the rotation of the grinding ring and grinding roller to extrude, impact and grind the material into a fine powder. The vertical mill is a kind of grinding-based equipment, and its working principle is to use the rotation of the grinding disc and grinding roller to make the material be extruded, ground and sheared in the grinding area, so as to obtain fine powder.
Second, structural characteristics.
The structure of Raymond mill is relatively simple, mainly composed of the main engine, analyzer, fan and other parts. The structure of the vertical mill is more complex, mainly composed of the main engine, the separator, the conveying device and other parts.
3. Scope of application.
Raymond mill is suitable for processing materials with high hardness and low moisture content, such as limestone, gypsum, marble, etc. The vertical mill is suitable for processing materials with low hardness and high moisture content, such as pulverized coal, slag, etc.
Fourth, production capacity.
Because the Raymond mill crushes materials by extrusion, impact, grinding, etc., its production capacity is large, and it can generally reach an output of several tons per hour. The vertical mill is a grinding-based equipment, and its production capacity is relatively small, generally only a few hundred kilograms per hour.
5. Environmental pollution.
The Raymond mill will produce a certain amount of dust and noise pollution during operation. The vertical mill adopts advanced sealing technology and dust removal device, which can effectively reduce dust and noise pollution.
Sixth, ** and maintenance costs.
Raymond mills are relatively low and have low maintenance costs. The vertical mill is relatively high, and the maintenance cost is also higher.
To sum up, there are obvious differences between Raymond mill and vertical mill in terms of structure, working principle, scope of application, production capacity, environmental pollution and other aspects. Therefore, when choosing which equipment to use, it is necessary to consider comprehensively according to the actual situation.
