Guinea exports unprocessed copper ore at $45/ton while importing 150-mesh copper ore powder at $280/ton, resulting in significant resource value loss.
Frequent voltage fluctuations (380V±20%) and occasional short power outages in mining areas pose severe challenges to continuous equipment operation.
The 150-mesh output is specifically required for downstream flotation separation of copper minerals, demanding strict particle size uniformity (no over-grinding or under-grinding).
High temperature (up to 38℃) and dusty conditions in Guinea's mining areas; limited local maintenance capabilities require equipment to be durable and wear parts to be easily replaceable.
| Component | Model/Spec | Guinea-Specific Benefits |
Main Grinding Equipment | Φ1200×4500 Ball Mill (55KW) | Optimized cylinder structure and steel ball ratio, suitable for grinding hard copper ore; simple structure, adaptable to harsh working conditions in mining areas |
Wear Parts | High manganese alloy steel balls | Resists abrasion from hard copper ore, service life extended to 5+ months |
Increased the value of copper ore from $45/ton (raw) to $160/ton (150-mesh processed), realizing local resource value enhancement.
150-mesh output qualification rate reaches 95%, meeting the technical requirements of downstream copper concentrate flotation, with copper mineral dissociation degree ≥88%.
90% uptime even under unstable power supply; the voltage stabilization module and standby power support ensure no production interruption due to short power outages.
Engineering team can arrive at the quarry at any time to guide installation, provide employee training, and assist with equipment commissioning.
The ball mill's impact and grinding combined working principle is highly suitable for copper ore with high hardness and uneven particle size, ensuring effective dissociation of copper minerals
Equipped with a dedicated voltage stabilizer and energy storage unit, it can withstand ±20% voltage fluctuations and 15-minute short power outages, perfectly matching Guinea's power supply conditions.
3.The ball mill has low initial investment and maintenance costs; the high-manganese steel balls are wear-resistant, reducing the frequency of spare parts replacements in remote mining areas.
1. High-efficiency grinding design adapted for high-hardness copper ore.
2. High-efficiency grinding design adapted for high-hardness copper ore.
3. Durable and easy-to-maintain structure suitable for harsh environments.
"We used to export raw copper ore at a low price, but now with WOCATO's ball mill, we can process 2-3 tons of 150-mesh copper ore powder per hour locally. The equipment runs stably even when the power fluctuates, and the particle size of the finished product is very uniform, which is highly praised by downstream flotation plants. This ball mill is tailor-made for Guinea's copper ore processing needs!"
