Vertical mill and Raymond mill are commonly used in non-metallic mines. （HCM Machinery）Guilin Hongcheng Mining Equipment Manufacturing Co., Ltd. is a manufacturer of grinding machinery and equipment. We produce HLM series vertical mill and HC, HCQ, R series Raymond mill have been widely used and recognized in the market. Among them, HLM vertical mill is more and more popular in the market because of its excellent energy-saving effect and production capacity. So, what are the advantages of the vertical mill and Raymond mill? Today we will analyze the answer for you.
1. Advanced technology system:
a. Vertical mill can adopt external cycle process, the system is more power-saving, and the labor intensity of workers is small. Raymond mill can not use external cycle process.
b. The position of the main motor, air inlet, air outlet, feed port and slag discharge port can be adjusted according to the requirements of the process position, and the feeding method can be used according to the water content of the raw material to adopt side feed or top side feed, saving project investment; And Raymond mill can't do that.
c. Vertical mill can achieve large-scale production, low energy consumption, high efficiency. Suitable for the scale and modernization of enterprises; Raymond mill specifications are small, low production capacity, high energy consumption (20~50% higher than the vertical mill unit product power consumption), can not achieve the scale of the enterprise.
2. Equipment structure:
a. The vertical mill adopts hydraulic mechanism to pressure, and the roller turning roller mechanism draws on LM vertical mill structure of German Lecher Company, which can be started with light load and easy maintenance. When working, the roller pressure can be adjusted in the control room according to the operating state of the mill.
b. Vertical mill roller sleeve, liner using alloy casting or composite surfacing welding, the shape is tire shape, can be used over, and the German extraordinary company MPS vertical mill similar, improve the utilization rate of wear-resistant materials. Generally, the life of the roller sleeve and liner is about one year.
c. The bearing seal of vertical grinding roller adopts simple and reliable mechanical seal, does not require sealing fan, and can also use thin oil circulation cooling and lubrication, which greatly improves the bearing life.
d. Compared with Raymond mill, vertical mill has no direct contact with the grinding body, and the preparation of powder is safer, energy-saving, and less impurities. Raymond mill adopts swing roller to pressure by centrifugal force, which can not avoid the situation of roller and ring collision
3.. Overhaul:
When the roller sleeve and liner plate are replaced by the vertical mill, the maintenance cylinder can be used to turn the roller out of the mill shell, and there are three working faces that can work at the same time, which is convenient for the owner to concentrate on the limited manpower and material resources. Generally, it can be completed in about 8 to 24 hours.
4. Production operation:
The vertical mill operation has a high degree of automation, can be started with light load, without pre-grinding the inner fabric, will not cause startup failure due to the instability of the material layer in the mill, and can be started twice in a short time. When the system has a short time failure, such as cutting out the material, the mill can lift the roller to wait for the fault to be removed.
In summary, the vertical mill and Raymond mill have many incomparable superior performance. However, the initial investment cost of the vertical mill is much higher than that of Raymond mill. Therefore, the vertical mill can not completely replace the status of Raymond mill in non-metallic ore processing. Customers can choose flexibly according to their needs.
