The three major accessories of the blade, grinding roller and grinding ring are the grinding that are most likely to wear and directly contact the material.

So how to slow down the wear of these three wearable parts?

First of all, we need to know what factors are related to wear: the hardness of the material, the harder the material, the higher the degree of wear when grinding, and the re-grinding of materials with lower hardness is less wear on the grinder. For materials with higher hardness, it is necessary to choose better wearable parts, such as manganese 13, or better grinding roller rings made of high-chromium alloys.

In the case of ensuring the efficiency of powder output, reduce the speed of the Raymond mill as much as possible, which can not only reduce the power consumption, but also effectively reduce the degree of wear and extend the service life. Wearing parts need to be overhauled regularly and severely worn parts to be replaced to ensure the best condition of the Raymond mill.

The whole structure of Raymond mill is composed of the main engine, analyzer (separator), pipeline device, blower, finished cyclone separator, jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control motor, etc. The Raymond mill host is composed of a frame, an air intake volute, a shovel, a grinding roller, a grinding ring, a cover and a motor. In order not to delay the progress of the work, you can get a spare.

Raymond mill in the work is mainly the use of shovel, grinding roller, grinding ring to achieve material crushing, therefore, shovel, grinding roller and grinding ring is an important wearing parts equipment of Raymond mill, only have a full understanding of it, in order to improve work efficiency in the work, to maximize the comprehensive benefits.

1. The shovel blade of Raymond mill is mainly used for the material to shovel into the grinding roller and the grinding ring, and the shovel blade is in contact with materials of different quality and hardness for a long time when the material is constantly shoveled, which is very susceptible to wear, and the severely damaged shovel blade will not be able to shovel up the material, resulting in the work efficiency of the Raymond mill being affected to a certain extent. Therefore, the blade structure of the Raymond mill is mostly made of steel materials with good wear resistance to ensure that the blade reaches the longest service life.

2. The grinding roller and grinding ring of Raymond mill are the crushed parts of the whole equipment, and the material is squeezed and rotated by the grinding roller on the grinding ring after being fed between the grinding roller and the grinding ring, so the grinding roller and the grinding ring are not only subject to the friction of the material, but also by the friction between them. When the grinding roller and grinding ring are seriously worn or unevenly worn, it will also affect the production of fine powder of the material, and the fineness of the finished product will be uneven. In order to ensure the fineness of the finished product, the grinding rollers and grinding rings of Raymond mill are made of wear-resistant steel materials with high strength and toughness, which makes it more applicable to a wide range of materials and has an excellent grinding effect on a variety of materials.
