Data on Unscheduled Downtime

Fri, 09 Oct 2026 16:48:31 GMT

Unscheduled Downtime Revenue Impact

Concrete • Aggregate / Crushing • Asphalt

A practical benchmark for estimating gross production revenue exposed when an industrial materials facility experiences an unplanned shutdown.

What the Metric Means

Gross production revenue at risk = normal production volume that cannot be produced during the shutdown × representative selling price.

Disclosure: this metric is a production-value benchmark, not a claim that every dollar becomes permanently lost revenue.

· Excluded from the headline figures: idle labor, trucking/hauling disruption, restart and troubleshooting time, overtime, rejected or spoiled material, downstream crew delays, missed delivery windows, contractual impacts, and customer schedule disruption.

· Actual financial exposure varies by product mix, local pricing, plant utilization, shift length, inventory buffers, ability to make up production later, and whether downstream operations are also interrupted.

· For sales and maintenance discussions, use “gross production revenue at risk” rather than “lost profit” or guaranteed “lost revenue.

Aggregate / Crushing Revenue Exposure

Aggregate operations vary widely in throughput. The table below uses the 2026 YTD Vulcan freight-adjusted aggregate selling price of $22.89/ton and an 8-hour production day for the hourly benchmark. The 3–5-day column models downtime while obtaining parts and completing repairs, from experience when a failure occurs there are three to five full production days interrupted waiting on parts.

Practical Uptime Message

Four hours matters. At representative production rates, four hours of unplanned downtime can place approximately $94,000 of ready-mix production, $17,000 of aggregate production, or $127,000 of asphalt production revenue at risk.

That makes preventive electrical maintenance, critical-spares planning, controls troubleshooting, condition monitoring, and rapid emergency response easier to evaluate against the economic exposure of a shutdown.

Before & After Service Work

Field Repair: From Wiring Chaos to Professional Craftsmanship

THE BEFORE

Not every electrical problem starts inside a new panel.

Our technicians recently arrived at a field installation where years of modifications had left wiring disorganized, difficult to trace, and challenging to service. Rather than simply making the immediate repair and moving on, the CESI technician took the time to troubleshoot the system, correct the wiring, improve routing and organization, and leave the installation in a condition that could be safely and efficiently serviced in the future.

The difference is visible.

What began as a confusing collection of field wiring was transformed into a cleaner, more organized installation that reflects professional electrical craftsmanship.

At CESI, craftsmanship does not stop when the panel leaves the shop. The same attention to detail we put into our manufactured panels goes with our technicians into the field.

Winter Maintenance Program

Mon, 19 Aug 2024 23:07:46 GMT

Save Time. Save Money.

Winter maintenance = summer electrical reliability.

The facilities we provide preventative maintenance, we find many items that need correction and fix them by the outline of the following scope of work:

Inspect and correct terminations.

a. Color of the wire.

b. Correct torque.

c. Inspected the power supplies, neutrals and grounding.

e. Insulation checks on SOW, GGC cord, grounding and motor terminations.

2. Circuit breakers and contactors.

a. Open the contactors and inspect the contacts. Recondition them and mate them to each other.

b. Look for temperature signatures.

c. Check setting on circuit breaker.

3. Overload, torque leads, check and adjust settings to nameplate information and multipliers allowed by NEC Code.

4. Refurbish.

a. Have the tools and cleaners for contacts, wire, and controls terms.

b. Install electrical grease.

c. Replace contacts that are close to failure, wire and cord as needed.

This list (not complete) should be performed by an experienced electrical personnel that has experience with torque, circuit breaker, contactor rebuild and ground. The facilities that have had this done, have experienced excellent reliability.

Speed Wheels & Whirligig

Mon, 19 Aug 2024 22:21:44 GMT

Speed Wheel

The speed wheel is a motion-tracking device for conveyor belts, designed to prevent nuisance trips caused by heavy loads or belt hopping. Unlike traditional sensors, it maintains constant contact with the belt, ensuring reliable rotation detection and avoiding unnecessary shutdowns.

To further enhance reliability, the speed wheel can be paired with a timing control cabinet featuring a time-delay relay. This allows users to fine-tune shutdown timing to match production needs, minimizing false trips and optimizing flow.

Integrated into an interlocking system, the speed wheel helps coordinate equipment in a chain reaction. If a downstream conveyor shuts down, upstream equipment automatically halts to prevent material pile-up and equipment overload—critical for safety and efficiency.

Interlocking links equipment states together, ensuring that if one part of the process stops, related components do too. For example, if a crusher’s discharge conveyor stops, the crusher itself should also shut down to avoid overflow.

Manufactured in Loveland, CO, the speed wheel is built from Grade A steel with a replaceable wheel, engineered for long-term performance.

Whirligig

This device which can be mounted magnetically and is a Universal Target / Mount Motion Sensor. Tracks the rotation and moves travel conveyors! The force of the traveling conveyor winds a mechanism inside of the Whirligig device and when it calls for travel it releases the tension held within and moves the travel conveyor to the desire position set by the operator. Very cool technology. Simple and easy to install and use.
