How to Reduce Downtime in Mining Crushing Operations

The significance of downtime in mining operations cannot be overstated, as it greatly affects operational efficiency and profitability. When a primary crusher becomes immobilised, it disrupts the entire downstream process. Emergency repairs tend to be five times more expensive than scheduled maintenance.

As such, choosing crushing plant maintenance becomes a strategic decision and a financial imperative for crusher downtime. To stay competitive, mining operators need to make an investment in dependable, up-to-date track-mounted crushing solutions. By following a few proven maintenance practices, the unexpected crusher downtime can be handled well.

What is Downtime in Mining Crushing Operations?

Downtime in mining crushing operations is a period when a crusher halts production. It is a massive profit drain in which interconnected downstream processes, such as haul trucks, loaders, and conveyor belts, sit idle.

There are two types of downtime: scheduled and unscheduled.

Scheduled crusher downtime refers to planned interruptions of operations for maintenance, repairs, or upgrades. It’s a convenience for the company and minimises any negative impact on the stakeholders.

On the other hand, unscheduled crusher downtime occurs unexpectedly and is usually due to equipment breakdowns, failures, or other unforeseen issues.

In this blog, read ahead on how miners can strategically reduce the downtime in crushing operations.

1. Transition to Data-Driven Predictive Maintenance

Relying on scheduled maintenance or manual inspections often means identifying an issue only after the wear has occurred. Transitioning your crushing plant maintenance to a continuous, telemetry-backed predictive model allows you to address localised mechanical fatigue before it causes a catastrophic breakdown.

• Contemporary high-throughput facilities: use specialised technology that tracks key elements such as bearing temperature, eccentric drive pressure, and vibration. An anomaly detected in time means that you can avoid a potential disaster and instead manage your crusher downtime in a controlled environment.
• The Keestrack-er Way: The Etrack Crushers have integrated this system into all of their plants. The company offers a unique Keestrack-er Remote Monitoring System for all the mobile crushers. It monitors operating conditions and identifies any signs of wear, minimising the unpredictability of plant operation downtime.

2. Streamline Material Feed and Champion “Choke Feeding”

Mechanical issues are not the sole cause of wear and tear of crushing machinery. Poorly managed upstream materials can also choke crushing circuits. So they create blockages.

• Eliminate Oversized Material Delays: When uncrushable boulders bypass primary screening, they jam the crusher cavity. This requires operators to halt operations and deploy manual rock-breakers. Installing automated boulder detection systems on feed conveyors can help to divert oversized rock efficiently.
• Enforce Steady Choke Feeding: Keeping the jaw, cone, or impact crusher cavity consistently full ensures that material rubs against material rather than pounding directly on the steel.

3. Upgrade to Advanced Hybrid-Electric Equipment

Traditional, purely hydraulic crushing rigs had thousands of meters of complex piping and hydraulic pumps. Every single structure of crushers represents a potential leak point that causes a complete system shutdown.

• Lower Mechanical Complexity: Modern crushers, especially the track-mounted crushers, are less complex. The subtle hydraulic lines eliminate the leaks and pressure drops that frequently trigger extended crusher downtime.
• Etrack Hybrid Technology: The mobile crushing equipment is built using advanced hybrid-electric technology. They have highly efficient electric drives alongside load-sensing hydraulics and eliminate complex wear points. Overall, using electric and mobile crushing equipment reduces the possibility of downtime and ensures maximum structural reliability.

4. Optimise Chamber Engineering and Wear Liner Replacement

Changing heavy manganese liners is one of the longest routine maintenance tasks in mineral processing. Earlier, a lot of time is wasted inside the crusher chamber to replace the wear and tear line, but now the following means are being used to:

• Execute Chamber Audits: To reduce the crusher downtime in mining operations, partner with processing specialists to regularly analyses the targeted ore profiles. Altering the configuration of liners to match the precise abrasiveness of minerals.
• Priorities Modular Accessibility: Look for mobile equipment designed from the ground up for easy servicing. Etrack’s Mobile Stone Crushers feature wide-opening maintenance access points and modular components. They are engineered to allow field mechanics to swap out wear liners swiftly and safely.

5. Standardize On-Site Spare Parts Management

Even the most advanced predictive software cannot prevent downtime if the technicians are stuck waiting weeks for a critical replacement part.

• Secure Localised Parts Channels: It’s crucial to map out the highest-turnover components, such as toggle plates, blow bars, mantles, and filters, to maintain a dedicated inventory on-site.
• Leverage Lifecycle Support: To eliminate supply chain bottlenecks, partner with an OEM that maintains a strong domestic presence. Etrack Crushers Private Limited provides reliable domestic Spare and Wear Parts Support. Having genuine, factory-spec spares readily accessible ensures that the maintenance team can execute repairs without delay.

On a Concluding Note

Do not allow unforeseen breakdowns to take away the profit potential of mining operations. With Etrack’s core philosophy, “performance in every detail”, the company provides a reliable affiliate of various kinds of crushers. To reduce crusher downtime, it manufactures mobile track-mounted jaw, cone, and impact crushers designed for mines in the toughest mining conditions.
