在坦桑尼亚进行的1,000吨/天石墨矿石处理测试及完整设备厂

矿石破碎与粗排序：

• Flow: Two-stage crushing (颚式破碎机 + Hammer Crusher) to below 25mm.
• Equipment: X射线传输（XRT）传感器基础分拣机 (optional).
• Function: Early waste rejection to improve head grade and reduce downstream processing load.

片状保护与分类：

• Equipment: 特种石墨鳞片保护磨粉机 (low-speed attrition grinding) + 多级筛分与重力分级器.
• Function: Separate flakes by size (+80 mesh, +100 mesh, -100 mesh) and remove slimes.

浓缩脱水与干燥：

• Equipment: 高效浓缩机 + 膜片过滤压滤机 + 低温带式干燥机.
• Function: Efficient moisture reduction to ≤ 10% while preventing oxidation.

模块化和集装箱化设计: Major equipment pre-assembled in container modules for rapid deployment and commissioning in remote Tanzanian sites.

灵活且数据丰富的试点电路： The plant is fully instrumented for variabile ore tests, providing accurate scale-up data for a future 5,000–10,000 TPD commercial plant.

水效与干堆尾矿： Tailings are fully dewatered for safe dry stacking, minimising environmental footprint and water consumption—critical for water-sensitive regions.

研磨与释放：

• Flow: Closed-circuit grinding with 球磨机 + 水力旋流器组.
• 目标研磨粗细： P80 = 0.3–0.5 mm (protecting flake structure).
• Function: Liberate graphite flakes while minimizing over-grinding.

多级浮选：

• Flow: 1个粗加工器 + 3个清洁器 + 1个拾荒者 flotation circuit.
• Equipment: 机械搅拌浮选池 with tailored frother/collector dosing system.
• Function: Achieve high-purity concentrate through repeated cleaning; scavenger recovers middlings.

尾矿与水管理：

• Equipment: 深锥浓缩机 + 滤 presse 机 for tailings; 水循环系统 with clarifier.
• Function: Dry stacking of tailings, >85% process water recycled.

高效浮选与智能控制： Automated reagent dosing and air flow control based on real-time pulp density and grade analysis.
