The key to graphite ore grinding is to protect the large scale, in order to better understand the graphite ore, and match it with appropriate grinding process and grinding equipment, this paper introduces the classification of graphite ore, grinding technology and commonly used grinding equipment in depth.
1. Crystalline graphite ore
(1) flake graphite
This type of "conductive experts" scale integrity directly determines the price of the product. We designed for a lithium enterprise "three-stage scale protection program": rough grinding with ball mill to open the ore → vibration mill to refine → rapid flotation to collect the scale, and finally achieve more than 85% of the large scale retention rate.
(2) Lumpy graphite
For a refractory plant transformation case, the use of “microwave + ball mill” combination of technologies, so that the lump graphite heat-resistant indicators to improve the two levels, but the energy consumption of tons of products fell by 18%.
When graphite meets mill, the choice of the right technology is the key to open the treasure.
2. Cryptocrystalline graphite
This type of "lubrication master" needs fine processing. We developed the "nanoscale dissociation process", by adjusting the ratio of mill media, we successfully extended the lubrication life of the product to 4000 hours for a seal manufacturer.
3. Hybrid graphite
In the renovation project of a mine in southwest China, the overall utilization rate of mixed graphite jumped from 68% to 92% by adopting the system of "Classified Grinding + Intelligent Proportioning".
When graphite meets mill, precise adjustment can stimulate the maximum value.
Switch processing mode according to graphite characteristics:
1. Scale graphite grinding
Vibration mill "shock mode": through the frequency control, the scale breakage rate is controlled within 5%.
Rapid flotation "blitzkrieg": prioritize the recovery of dissociated flakes and shorten the process by 30%. 2.
2. Cryptocrystalline graphite grinding
- Micron-level control of ultra-fine grinding: ball mill with special liner ensures that 95% of the particles are less than 10μm.
- Flocculation and flotation "clean action": the patented pharmaceutical formula reduces the impurity entrainment by 40%.
3. Mixed graphite grinding
For the grinding of mixed graphite ore, a comprehensive process should be chosen, that is, combining the grinding technology of crystalline and cryptocrystalline graphite, which is adjusted according to the needs of specific applications.
We have compiled field-proven equipment combination options:
| Graphite Type | Recommended Equipment | Efficiency Indicators |
|---|---|---|
| Scalar Graphite | Vibratory Mill + Vertical Stirred Mill | Large Scale Recovery +35% |
| Cryptocrystalline Graphite | Nano Ball Mill + Flocculation Flotation Machine | Lubrication Performance +50% |
| Mixed Graphite | Intelligent Grinding System + Photoelectric Sorting Machine | Combined Utilization Rate +25% |
From lab to production line, we provide not just equipment, but grinding solutions proven in 200+ projects. When your graphite processing encounters bottlenecks, our EPCM+O service team will bring this set of practical mapping to customize a whole-process efficiency solution for you, from mineral analysis to product output - because true beneficiation wisdom is always based on reading the "language" of the ore.
