5 Maintenance Checks Every Aggregate Plant Should Do Before Production Season

As spring approaches, aggregate operations begin ramping up production. March is the ideal time to take a step back and make sure your plant is ready for the busy season ahead. A few proactive maintenance checks now can help prevent costly downtime later. At Process Machinery Inc., we work with producers every day who rely on preventative maintenance to keep material moving and equipment performing at its best.

Here are five key areas every plant should review before production season hits full stride.

1. Crusher Wear Components

Crushers take the brunt of the work in most operations. Before production increases, inspect critical wear parts such as:

Jaw dies, mantles, concaves, and blow bars
Feed plates and wear liners
Chamber profiles and liner seating

Worn or improperly seated liners can reduce throughput, increase recirculating loads, and lead to unnecessary stress on equipment.

2. Screening Equipment

Screens play a critical role in maintaining product specifications and plant efficiency. A quick inspection should include:

Screen media condition and attachment integrity
Tension rails and crown bars
Springs and vibration components
Structural welds and side plates

Properly maintained screens help maintain consistent sizing and prevent unnecessary wear on downstream equipment.

3. Conveyor Systems

Conveyors keep material flowing through the plant, but they’re often overlooked until something goes wrong. Key items to check include:

Belt tracking and alignment
Idlers and pulley condition
Skirting and sealing systems
Belt cleaners and scrapers

Even small adjustments can improve efficiency and reduce material spillage throughout the plant.

4. Wash Plant Equipment

For operations running sand and gravel plants, wash equipment should also be evaluated before production ramps up. Inspect components such as:

Screw washers and classifying tanks
Pumps and piping systems
Dewatering screens
Fine material recovery systems

Maintaining proper water balance and equipment condition ensures consistent product quality and optimal material recovery.

5. Lubrication & Oil Health Proper lubrication is critical to the health of crushers, screens, and other rotating equipment.

That’s why quarterly oil sampling and following factory-recommended oil change intervals are essential. Oil analysis can detect contamination or early wear before problems develop into costly failures. Combining routine inspections with oil monitoring helps maintenance teams stay ahead of potential issues.

Stay Ahead of the Season

Taking the time now to inspect key plant components can help reduce downtime, extend equipment life, and keep your operation running efficiently throughout the busy months ahead. If you’re evaluating your plant before production ramps up, the team at Process Machinery Inc. is ready to help.
