How to improve the service life and capacity of Raymond Mill?

  • How to improve the capacity of Raymond Mill?

    Raymond mill equipment has been widely used in many industries, the use of Raymond mill to control the nature of the material, can not be too hard, too wet, too sticky, if the material is too wet, it can be air dried and other methods to deal with, want to improve the output of Raymond mill, it is necessary to do the following, so that it is possible to improve the output:

    1. Material properties

    The hardness, humidity and other properties of the material will also have a greater impact on the processing capacity. For the materials with high hardness and high humidity, it is difficult to deal with in the grinding process, and it is easy to have problems such as adhesion, so the processing capacity is smaller. For the materials with low hardness and low humidity, it is easy to grind, so the processing capacity is larger.

    2. Product fineness requirements

    Different customers have different requirements for the fineness of the finished product after grinding. If the user has very high requirements for the fineness of the finished product, the finer the material, the smaller the grinding capacity. On the contrary, if the user's requirements for the fineness of materials are low, the processing capacity will naturally increase.

    3. The humidity of the material is not good. When the moisture content of the material to be ground is relatively large, it is easy to adhere in the process of grinding, which will cause blockage and affect the processing capacity.

    How to improve the service life of Raymond Mill?

    In order to prevent the corrosion and wear of Raymond mill, various new processes and methods have appeared in recent years. From the economic and technical point of view, Raymond mill often uses metal or non-metal protective layer on the surface of parts, such as covering the metal surface with zinc, chromium, nickel, tin, copper, aluminum, lead and other metal materials by heat treatment, electroplating or metal spraying, Or paint (sefan, qingfan, mineral oil, Vaseline, paraffin solution, etc.) on the surface of parts as anti-corrosion coating.

    The hot wear parts of Raymond mill work directly under the condition of high temperature, the metal surface will be severely oxidized, the mechanical properties of the metal and the geometric dimensions of the parts will be affected, and even the surface of the parts will be burned.

    This kind of damage caused by high temperature is called thermal wear. There are a lot of Raymond mill equipment in the factory are working at a very high temperature, such as the ironmaking furnace of the metallurgical factory, the accessories of the refining furnace, the accessories of various heating furnaces, the accessories of the pot calciner, rotary kiln and its accessories of the carbon cable factory, the accessories of the roasting furnace and the graphitization furnace, etc. Because these equipments and accessories work under high temperature for a long time, the phenomenon of thermal wear is very serious.

    The degree of thermal damage of Raymond mill parts depends on the high temperature and temperature of the parts in the work and the time of bearing load under this high temperature condition. Some parts work under the condition of high temperature and heavy load for a long time, and their thermal wear is serious. While some parts work under the condition of high temperature, because the heating time of Raymond mill is not long, or periodic heating and cooling, the effect of thermal wear is also slight.

    Whether the parts of Raymond mill can maintain the stability of oxidation at high temperature is an important condition for the parts of Raymond mill to work continuously at high temperature. The initial stage of surface oxidation is a chemical process. When the oxidation is further strengthened, it becomes a complex thermochemical process.
