high-chromium alloy rollers for Raymond mill
high-chromium alloy ring for Raymond mill
The picture on the left shows the high-chromium alloy grinding rollers and grinding rings customized by Cronus Machinery Co., Ltd. for a customer in Pakistan. These are mainly used in the 130 model of the Raymond mill. It is known that the customer processes talc and has very high requirements for the whiteness and purity of the product.
Why do we choose high-chromium alloy as the material of Raymond mill’s roller and ring?
High Cost-effectiveness
Although the initial cost of high-chromium alloy may be slightly higher than that of some common materials, its excellent performance can greatly prolong the service life of the grinding rolls and grinding rings, reduce the replacement times and downtime, and reduce the maintenance and repair costs. In the long run, the use of high-chromium alloy materials can bring better economic benefits to enterprises and improve the stability and continuity of production.
Corrosion and Oxidation Resistance
The presence of the chromium element makes high-chromium alloys have good corrosion and oxidation resistance. In the grinding process, the grinding rolls and grinding rings may come into contact with some corrosive substances or work in a high-temperature environment. The corrosion and oxidation resistance of high-chromium alloy can prevent its surface from being corroded and oxidized, and avoid the decrease of material performance and the aggravation of wear caused by corrosion and oxidation, further prolonging its service life.
High Strength and Toughness
High-chromium alloy has a certain strength and toughness while having high hardness. Although its toughness is slightly lower than that of high-manganese steel and other materials, through reasonable composition design and heat-treatment process, it can ensure that it will not be easily broken or crushed when subjected to a certain impact load, thus ensuring the normal operation of the flour mill. For example, in some large-scale flour mills, by optimizing the formula of high-chromium alloy, it can bear greater grinding pressure and impact, and at the same time, maintain good wear resistance.
Good Wear – resistance
The high-hardness characteristic endows the high-chromium alloy with excellent wear resistance. When the flour mill is working, the grinding rolls and grinding rings will be in repeated extrusion, grinding and friction with various hard materials, and the wear is very serious. The wear resistance of high-chromium alloy is much higher than that of ordinary alloy steel and cast iron. It can effectively reduce the wear amount in long-term work, reduce the replacement frequency, so as to improve the production efficiency and reduce the maintenance cost.
High Hardness
High-chromium alloy contains a large amount of chromium, which can form hard carbides. These carbides are uniformly distributed in the matrix, making the material very high hardness. Its hardness can usually reach about HRC50-65. This high hardness can effectively resist the cutting and wear of the material on the surface of the grinding roll and grinding ring during the grinding process, maintain the dimensional accuracy and surface quality of the parts, and prolong their service life.
Which components can be customized to be made of high-chromium alloy?
The wear-prone parts of the Raymond mill can be customized to be made of high-chromium alloy. This material can significantly reduce the wear of the grinding rollers and grinding rings, greatly extending the service life of the equipment.
What kinds of equipment are the high-chromium alloy materials applied to?
Cronus Machinery Co., Ltd. not only can customize the materials for your grinding rollers and grinding rings, but also can provide overall customization for the materials of components such as pipes and fans. For instance, it can replace ordinary cast steel with stainless steel to significantly improve the purity of the fine powder. Additionally, by adding high-strength magnetic separators, the content of iron powder can be reduced. In summary, you can boldly express your product requirements, and the rest will be handled by our technical engineers. We will carefully consider your product requirements and tailor-make suitable production line equipment for you.
