Work Principle

The High-Capacity Ball Mill stands as a cornerstone in ore processing, designed to deliver exceptional grinding efficiency for various mineral ores. Available in both grid-type and overflow-type configurations, this mill caters to diverse industrial needs, from primary grinding in large-scale mines to fine grinding in beneficiation plants. With a production capacity ranging from 100-500 t/h, it ensures consistent performance in processing gold, copper, iron, and other metallic ores.

Grid-Type Ball Mill Mechanism

The grid-type variant features a perforated grid plate at the discharge end, equipped with 7-20 mm diameter holes. After grinding, ore slurry passes through these holes and enters fan-shaped chambers lined with radial ribs. As the mill rotates, these ribs lift the slurry to the hollow shaft neck, enabling forced low-level discharge. This design minimizes over-grinding by expelling fine particles promptly, making it ideal for coarse grinding (48-65 mesh) .

Overflow-Type Ball Mill Mechanism

In contrast, the overflow-type mill lacks a grid plate. Instead, its discharge shaft incorporates anti-spiral blades that return stray steel balls and coarse particles to the grinding chamber. Ore slurry exits naturally when it exceeds the shaft’s lower edge, resulting in a longer residence time. This configuration produces finer particles (150-200 mesh) suitable for secondary grinding stages .

Grinding Dynamics

Both types rely on steel ball impact and abrasion. Grid-type mills operate at higher rotational speeds, generating greater ball drop heights for impact-dominant grinding. Overflow-type mills use slower speeds, emphasizing grinding action for finer outputs .

Advantages

Tailored Efficiency

Grid-type mills boost productivity by 10-15% compared to overflow models under the same conditions, making them ideal for large-scale operations. Overflow-type mills achieve superior particle fineness, reducing downstream processing costs .

Durable Construction

Crafted with high-grade manganese steel liners and wear-resistant components, the mill sustains 20,000+ hours of continuous operation before major maintenance. Its robust drive system minimizes downtime, even in harsh mining environments.

Energy-Saving Design

Equipped with a frequency-adjustable motor, the mill optimizes power consumption, achieving 30% energy savings compared to conventional mills. The grid-type’s forced discharge further reduces energy waste from over-grinding .

FAQ

What factors determine grid-type vs. overflow-type selection?

Choose grid-type for high-capacity, coarse grinding (e.g., 48-65 mesh) and overflow-type for fine grinding (150-200 mesh) in secondary stages. Grid-type suits large mines, while overflow-type simplifies maintenance for smaller operations .

How often should steel balls be replaced?

Under typical conditions, steel balls require replacement every 3-6 months, depending on ore hardness. The mill’s access doors facilitate easy ball replenishment without halting production.

Can it handle wet and dry grinding?

Yes, the mill adapts to both modes. Wet grinding uses water to form slurry, ideal for mineral beneficiation, while dry grinding suits scenarios where water scarcity is a concern.
