There are many second-hand things in life, such as used cars, used rice cookers, second-hand refrigerators, etc. So, can second-hand Raymond mills be compared with used cars?

As a car trading market, it is not difficult to find that a second-hand car is glamorously placed in front of the booth. Whether it is old or new or has an accident, it can be judged as a professional, in the case that our economy is not very abundant. We can consider second-hand cars in the scope of purchase, because his life cycle is long, the general service life is less than 15, relatively affordable, the discount rate is relatively low, the parts are well matched, and the choice is large.

The second-hand raymond mill is a far cry from the car. The so-called second-hand Raymond mill is a device that has been used by others for some time, or is a refurbished device, or a product that has been closed down by the manufacturer. Many manufacturers are blindly searching for cheap. In the online or local purchase of second-hand lightning machine, Raymond mill working principle is that the main body of Raymond mill is driven by the transmission to drive the central shaft during the working process. The top end of the shaft is connected with the Raymond mill plum The frame is equipped with a grinding roller device and forms a swinging pointing finger.

The grinding roller is self-propagating due to friction, and not only rotates around the center, but also revolves around the grinding ring. The lower end of the grinding roller under the plum blossom frame is equipped with a blade system, the blade During the simultaneous rotation with the grinding roller, the material is fed between the grinding roller rings, thereby forming a cushion layer, and then subjected to the centrifugal action generated by the rotation of the grinding roller to crush the material to achieve the purpose of milling.

However, do we know that after using the Raymond mill for a period of time, the grinding roller and the grinding ring need to be replaced regularly. Most of the components and components of the Raymond mill also need regular maintenance. In terms of service life, Raymond Mill's life cycle is roughly two to three years, in order to create more output, so that investors can maximize the benefits of production.
