Ultrafine tungsten carbide powder separation equipment horizontal screw centrifuge

The decanter centrifuge is a commonly used solid-liquid separation equipment. Due to its high efficiency and continuous operation, it is also widely used in the treatment of materials such as ultrafine tungsten carbide powder. The following is some information about the use of decanter centrifuge to separate ultrafine tungsten carbide powder: Working principle of decanter centrifuge The decanter centrifuge separates solids and liquids through the centrifugal force generated by the high-speed rotating drum and screw conveyor. The screw conveyor inside the drum pushes the solid particles to the outlet end of the drum, while the liquid is discharged through the overflow hole. Challenges in the separation of ultrafine tungsten carbide powder - Small particle size: The particle size of ultrafine tungsten carbide powder is usually very small, which increases the difficulty of separation. - High viscosity: The viscosity of tungsten carbide suspension may be high, requiring appropriate pretreatment or adjustment of operating parameters. - Wear: The high hardness of tungsten carbide powder may cause equipment wear. Points to note when using decanter centrifuge in the separation of ultrafine tungsten carbide powder 1. Equipment selection: Select a decanter centrifuge model suitable for handling ultrafine particles, and the pore size of the drum should be small enough to prevent the loss of fine particles. 2. Operating parameters: According to the characteristics of ultrafine tungsten carbide powder and separation requirements, adjust the rotation speed, differential speed and overflow hole size of the drum. 3. Pretreatment: In order to improve the separation efficiency, the tungsten carbide suspension may need to be pretreated, such as adjusting the pH value, adding dispersants or flocculants, etc. 4. Wear-resistant materials: Due to the high hardness and abrasiveness of tungsten carbide powder, parts such as the drum and screw conveyor should use wear-resistant materials or undergo surface treatment. 5. Separation efficiency: By optimizing operating parameters and equipment design, the separation efficiency can be improved and the residual solid particles in the liquid can be reduced. 6. Continuous operation: The decanter centrifuge is suitable for continuous operation and can meet the needs of large-scale production. 7. Maintenance: Regularly maintain and service the decanter centrifuge, check the wear and tear, and replace the worn parts in time. 8. Environmental protection and safety: Ensure that the emissions during the separation process meet environmental protection requirements while ensuring the safety of operators. Through the above measures, the decanter centrifuge can be effectively used in the separation process of ultrafine tungsten carbide powder to achieve high efficiency and high quality of solid-liquid separation.
