When machines stop, everything stops — production, progress, profit. You follow preventive maintenance routines, yet unplanned downtime still finds a way in. Why does it happen, and what can you do about it?

Maintenance planning and scheduling is one of those things most companies believe they already do well – until a breakdown stops production, spare parts aren’t available, or the wrong machine is offline at the wrong time. That’s when the real cost of poor scheduling shows up: lost output, inflated repair bills, and operators waiting for equipment that should have been ready.

Jaw crushers have been central to mining and aggregate production for decades – breaking down hard rock into the gravel, stone, and minerals that fuel construction and industry. But while the basic design has stood the test of time, the demands of modern production make jaw crusher efficiency more important than ever. Every hour of downtime means lost tons, rising costs, and frustrated schedules.

Quarries have been part of human infrastructure for centuries – from ancient stone blocks to today’s crushed gravel for roads, concrete, and construction. But running a modern quarry is is an altogether different proposition. Regulations are strict, equipment is complex, and every hour of production matters.

Launched in 2024, AggNexus has rapidly become a key forum for digital innovation in the aggregates, concrete, and broader construction materials industries. The 2025 Digital Innovation Forum took place from September 17–19 at the University of Texas at Austin, Thompson Convention Center, bringing together producers, vendors, and thought leaders to explore emerging technologies, operational improvements, and practical strategies for digital

Among the biggest challenges for a plant is downtime; it hits more than just production, impacting safety, trust, and margins. Yet the tools many teams still use for inspections and repairs, such as WhatsApp, spreadsheets, radio calls, or clipboards – slow them down.

Total Preventive Maintenance (TPM), also referred to as Total Productive Maintenance, is a proactive maintenance strategy designed to minimize reactive maintenance and unplanned downtime. In this article, we’ll explore what Total Preventive Maintenance is, its key benefits, and essential steps to consider when implementing a TPM system.

In the height of summer, even simple tasks can feel exhausting. For quarry workers, the intense heat is not only physically challenging but also adds layers of risk. As temperatures climb, so do the challenges and safety hazards across quarry sites.

You’ve likely heard of Overall Equipment Effectiveness (OEE), but do you really understand how it works or why it’s crucial for operational performance? In this article, we explain how to calculate OEE, what counts as a good score, and what to consider when choosing OEE tracking software.

Why preventive maintenance matters. Preventive maintenance helps you catch issues early—before they lead to costly breakdowns. This article covers key maintenance types and how to build a smart, future-proof plan using tools like CheckProof.
