Graphite Mohs hardness value: 1~2 (close to talc, slightly harder than gypsum). Good conductivity, often used in electronics, electrical and metallurgy. High temperature resistance, high melting and boiling points are the core of refractory materials. Strong lubricity, can reduce mechanical wear, used in machinery manufacturing. Stable chemical properties, suitable for making materials for chemical corrosion-resistant equipment.
Raymond mill is a powerful assistant for graphite processing. After the raw material is crushed by the crusher, it is sent to the main machine of Raymond mill through a vibrating feeder. The grinding roller is pressed on the grinding ring under the action of centrifugal force to rotate and grind. The scraper sends the material between the grinding roller and the grinding ring to crush. The fine powder is sent to the analyzer for screening through the airflow. The fine powder that meets the requirements is collected, and the coarse powder is returned for re-grinding.
Common problems in processing graphite with Raymond mill
Graphite characteristics affect the effect of production and processing. Due to its soft texture, it is easy to produce adhesion during processing, which requires strict control of particle size integrity during processing. At the same time, the high lubricity of graphite may cause equipment to slip, and targeted measures need to be taken to prevent it. To ensure processing efficiency, various process parameters must be precisely controlled.
In the process of processing graphite with Raymond mill, common problems mainly focus on insufficient production efficiency and poor particle uniformity. The key factors affecting production efficiency include: high hardness of raw materials, excessive moisture content, excessive initial particle size, and problems such as slippage of the grinding roller or poor ventilation system of the equipment itself.
Improvement measures for processing graphite with Raymond mill
For these problems, improvement measures include: optimizing material properties and pretreatment; checking and adjusting the pressure of the grinding roller, and replacing worn parts when necessary; increasing the speed of the fan, and cleaning the duct to ensure smooth ventilation. Uneven particle size is mainly caused by inappropriate classifier speed and blade wear, which should be solved by adjusting the speed of the classifier wheel and regularly updating the worn blades, while ensuring the accuracy of equipment installation. Dust leakage problems are usually caused by aging of seals, insufficient negative pressure or failure of the dust removal system. To avoid this situation, it is necessary to regularly check and replace aging sealing materials, maintain the dust removal system (including cleaning or replacing filter bags), and ensure that the fan can work properly by increasing the negative pressure.
The significant advantages of Raymond mill in graphite processing
The Raymond mill has high-efficiency crushing performance, suitable for soft materials such as graphite, equipped with an advanced grading system, and the particle size can be controlled from 80 to 1500 mesh. The unique lamination principle maintains the graphite structure, the particle size distribution is concentrated, the temperature rise is low and oxidation is prevented. Fully enclosed negative pressure operation, high dust removal efficiency, and energy consumption is reduced by 35%. The wear-resistant alloy parts have a long life and intelligent control. The equipment cost is low, maintenance is simple, and the footprint is small.
Conclusion
By optimizing key parameters such as roller pressure and classifier speed, the Raymond mill can give full play to its performance advantages in the field of graphite processing, and achieve high-efficiency and low-consumption large-scale production while ensuring product quality. Its excellent cost performance makes it the preferred equipment in the field of graphite processing.
