Primary crushing strategies and operational excellence

A holistic approach to mining operations is important, combining technical efficiency with a strong culture of operational excellence.

Jaw crushers

Jaw crushers are ideal for primary crushing of large, hard materials, offering high throughput and robustness.

Select models with large feed openings and maximum capacity, such as the Pioneer, Iron Giant, and Hydra-Jaw series. These advanced jaw crushers allow operators to safely clear the crusher from any location, minimising downtime and enhancing safety.

Engineered for maximum capacity, they can deliver up to 25 per cent more tonnes per hour compared to other equipment. Additionally, heavy-duty flywheels reduce horsepower requirements or less fuel, and their class-leading stroke increases capacity and operational efficiency.

Gyratory crushers

Suitable for high-capacity primary crushing, these crushers provide continuous crushing action, making them effective for large-scale operations.

Material challenges can be expected such as inconsistent feed or ore characteristics which are part of overall efficiency or desired throughput program.

A Chilean mining company was able, through a transformation initiative, to lead a 12 per cent increase in productivity and a 12 per cent decrease in costs per year. This was achieved through continuous improvement and operational excellence.

An Australian mining company faced with operational inefficiencies conducted thorough diagnostics and collaborative workshops, developing a tailored improvement roadmap. This approach enhanced productivity, streamlined operations, and fostered a culture of continuous improvement.

By adopting a culture of operational excellence, leading mining companies can drive sustained improvements in productivity, efficiency, safety, and sustainability. This involves aligning organisational practices with continuous improvement principles and fostering employee engagement.

Finally, having a clear vision and purpose aligned with operational goals will help drive consistent improvements and maintain focus.

Engage employees at all levels to foster ownership and accountability. Regular training and development programs can enhance skills and promote a culture of excellence. It is suggested to implement integrated digital systems for better visibility and decision-making, including real-time data analytics and performance monitoring.

Also, encourage a mindset of continuous improvement through frequent reviews, feedback loops, and adaptation of best practices.

The Astec team excels in establishing continuous relationships with major operators around Australia by providing equipment tailored to specific needs.

Ultimately, durability and long uninterrupted operational hours are key to optimised production operations. These insights highlight the dynamic nature of the mining industry in Australia, with a strong focus on adapting to market conditions and leveraging technology for improved efficiency, leading to better resource recovery and costs savings through equipment selection and use.
