1. PEMBUKAAN PAINPOINT DRIVEN

Are your grinding operations a persistent bottleneck in your mineral processing or material production line? Inefficient particle size reduction directly impacts throughput, kualiti produk, dan garis bawah anda. Common challenges with standard ball mill technology include:

Penggunaan Tenaga Berlebihan: Grinding mills can account for over 50% of a plant's total energy draw. Inefficient power transfer to the grinding media results in wasted kWh and unsustainable operational costs.
Masa Henti yang Tidak Dirancang untuk Penyelenggaraan: Perubahan pelapik yang kerap, kegagalan galas, and gear inspections halt production. Each hour of unscheduled downtime can cost tens of thousands in lost output.
Inconsistent Product Fineness: Achieving and maintaining a precise target P80 (80% passing size) is difficult with mills that lack process stability, leading to offspec product and downstream recovery issues.
High Media & Liner Wear Rates: Abrasive ores and improper charge motion accelerate consumption of grinding balls and liners, creating high recurring consumable costs and contamination risks.

Is your operation struggling with these cost centers? Soalan untuk pengurus loji adalah jelas: how can you increase mill availability, reduce specific energy consumption, and gain tighter control over your grind without compromising on robustness?

2. GAMBARAN KESELURUHAN PRODUK

The Custom Ball Mill is a precisionengineered tumbling mill designed for the continuous or batch grinding of various ores, Mineral Perindustrian, and raw materials. Engineered beyond standard catalog offerings, it is configured to match your specific comminution circuit parameters and feed characteristics.

Aliran Kerja Operasi:
1. Controlled Feed Introduction: Precrushed material is conveyed into the mill via a sealed feed chute.
2. Optimized Comminution: The rotating drum lifts the grinding media charge (balls/rods). Cascading and cataracting action applies impact and attrition forces to reduce particle size.
3. Pelepasan Tepat: Ground material exits via a peripherally located discharge grate (overflow or grate discharge), ensuring proper retention time for target fineness.

Skop Permohonan: Ideal for secondary and tertiary grinding stages in mining (base metals, logam berharga), cement clinker grinding, silicate products, and industrial mineral processing.

Had Utama: Not suitable for primary crushing of large feed sizes (>25mm biasanya). Optimal performance requires correct sizing based on Bond Work Index testing and circuit design.
