Graphite sagger is a high-temperature processing container made of high-purity graphite material. It is widely used in sintering, calcination, carbonization, and high-temperature heat treatment processes of powder and bulk materials, playing a crucial role, especially in the fields of lithium-ion battery materials, metallurgical powders, advanced ceramics, and electronic functional materials. It requires extremely high consistency, density, and structural stability of the raw materials, making the upstream raw material preparation process particularly important.
The Necessity of Graphite Sagger Mixing and Granulation Process
In the production of graphite saggers, graphite powder usually needs to be thoroughly mixed with binders, lubricants, and functional additives, and further agglomerated into particles with a certain particle size distribution to meet the process requirements of subsequent isostatic pressing, molding, and high-temperature sintering.
Through the mixing and granulation process, the fluidity, packing density, and molding stability of the powder can be significantly improved, while reducing the risk of stratification, segregation, and molding defects, laying the foundation for high-quality sagger products.
Core Functions and Technical Advantages of the Graphite Sagger Granulator
1. Efficient and Uniform Mixing
The inclined powerful mixer, through the composite three-dimensional movement of high-speed rotating stirring tools and the inclined cylinder, creates strong material tumbling, shearing, and convection effects in a short time, achieving dead-angle-free, high-uniformity mixing of graphite powder, binders, and various additives, effectively avoiding uneven agglomeration or localized excessive moisture.
2. Integrated Mixing and Granulation
The equipment can precisely control the amount and method of binder addition during the mixing process. Relying on mechanical force and friction between materials, the powder gradually agglomerates into particles with a stable structure and controllable particle size. This integrated granulation method significantly improves the molding fluidity and density consistency of the green body, providing reliable assurance for high-precision molding processes.
3. Energy-Saving, High-Efficiency, and Stable Process
The inclined structure design significantly improves mixing efficiency. The mixing and granulation time per batch is usually controlled within 3–10 minutes, which can reduce energy consumption by 30%–50% compared to traditional mixing equipment. At the same time, the equipment operates stably with good process repeatability, suitable for continuous and large-scale production needs.
4. Adapting to the Demands of High-End Material Processing
This type of equipment has been specifically optimized in terms of wear resistance, sealing performance, and ease of cleaning, meeting the requirements of low-contamination and high-consistency production environments for graphite and related powder materials.
Project Application Example
