SGX Series SAG Mill

The SGX Series SAG Mill is engineered for high-capacity primary grinding in mineral processing operations. Designed to process large volumes of hard and abrasive ores, such as copper, gold, and iron, this semi-autogenous mill combines the efficiency of ore-on-ore grinding with the added force of grinding balls to achieve optimal size reduction in a single stage.

Ideal for use in large-scale mining and concentrator plants, the SGX Series mill delivers high throughput with reduced energy consumption per ton of material processed. Its rugged shell construction, durable liner systems, and optimized drive configurations ensure long-term performance under the most demanding conditions.

The SGX Series is also compatible with modern automation systems and advanced process control solutions, allowing operators to fine-tune performance, maximize uptime, and minimize operational costs. Whether used in greenfield installations or plant upgrades, it provides the flexibility and efficiency required for reliable mineral recovery.

Key Features:

• Semi-autogenous design using ore and grinding media
