Animal feed production is a critical part of Australia’s and the world’s agricultural value chain. Companies like Ridley, Reid Stockfeeds, Harwood Grains, Cargill, New Hope Liuhe, Muyuan Foodstuff, BRF, ForFarmers, Tyson Foods, and Nutreco and others in the industry rely on smooth production to meet demand and maintain quality. But like any production environment, unplanned equipment breakdowns can bring everything to a halt, costing time, money, and risking supply chain commitments to farmers and partners.
In this post, we break down the hidden costs of downtime in animal feed production, look at some of the assets most likely to cause issues, and explore how predictive maintenance can reduce breakdowns and keep feed mills running smoothly.
Manufacturing animal feed involves a complex, continuous process, including grinding, mixing, pelleting, cooling, and packaging. This means a variety of rotating and processing equipment is constantly at work. Some of the most common culprits of downtime include the below.
Hammer mills are critical to breaking down grain, proteins, and additives into fine particles for animal feed. They rely on high-speed rotating shafts with hammers or blades.
Common Failures:
How Vibration & Temperature Sensors Help:
Mixers are essential for homogeneously blending nutrients, minerals, and proteins into feed. They use rotating shafts with paddles or ribbons inside large chambers.
Common Failures:
How Vibration & Temperature Sensors Help:
Pellet mills compress mixed feed into pellets using roller dies under high pressure. These are high-torque, high-pressure machines prone to mechanical stress.
Common Failures:
How Vibration & Temperature Sensors Help:
These systems move raw materials and finished feed through various production stages. Constantly in motion, they suffer from wear and misalignment.

This isn’t one you would have thought about at first. In fact you’re probably raising your eyebrows now. Here’s the thing; the small motors driving conveyors are particularly susceptible to being missed if you have very short maintenance windows. Add to this that some of these conveyors will be overhead and therefore hard to access, and you are prone to missing the classic belt wear and bearing issues on them.
For this reason, leveraging consistent vibration and temperature condition monitoring will do a great job here to prevent unexpected failures that could halt production. Here, you will be able to detect early signs of bearing degradation and belt wear, allowing maintenance teams to schedule repairs during planned downtime.
Some sites will have multiple dozens of these motors, and with some experiencing a MTBF that’s quite low, these can form a great part of a pilot program to prove the technology will work well at your site. We wrote more about how specifically we have a history of preventing failures on them in this article : From Preventive to Predictive Conveyor Maintenance in the food and beverage industry.
Coolers and dryers are used to remove heat and moisture from feed pellets, a critical step for quality and storage life. They involve rotating fans, conveyors, and blowers.

While every site is different, downtime costs for a large animal feed mill can quickly add up. Let's break it down:
Of course, this largely depends on your company's financial profile and the specifics of your site. However, based on numerous industry conversations, we estimate that, conservatively, a 4-hour unexpected breakdown could cost between $35,000 and $50,000—excluding the downstream impacts on supply chain and customer satisfaction.
Across Ridley, Reid Stockfeeds, Harwood Grains, Cargill, New Hope Liuhe, Muyuan Foodstuff, BRF, ForFarmers, Tyson Foods, Nutreco, and others in the animal feed industry, using indicators like continuous vibration and temperature monitoring will give a crucial early warning system, allowing maintenance teams to fix issues before they become breakdowns.
Instead of reacting to failures and scrambling for parts, predictive maintenance allows planned, cost-effective maintenance, keeping production lines moving and customers happy.
Whilst this certainly isn't the case for everyone, a number of animal feed production facilities we’ve spoken with will operate around the clock to meet consumer demand for their popular products. This 24/7 manufacturing schedule presents unique challenges when it comes to equipment maintenance. With limited downtime available, maintenance teams have extremely tight windows to inspect, repair, or replace critical assets.
Any unplanned failure that occurs during active production can be catastrophic. As one reliability manager noted, the costs of such incidents go far beyond maintenance - unplanned downtime is considered a "marketing cost" that impacts the entire business.
For such sites, continuous, online condition monitoring is especially helpful for maintenance planning. If you have planned maintenance work orders on all of your conveyor motors, but your limited time window won't allow you to cover all of them, then having critical asset data on these will be the best way to help you coordinate your efforts.
As we’ve suggested above when going over some key pieces of equipment, we’re seeing that implementing comprehensive vibration condition monitoring across critical assets has proven particularly effective for preventing unexpected failures in yogurt production. As a quick overview to dive deeper into some common failure modes, for filling machine motors, vibration analysis can detect:
In fermentation tank agitators, condition monitoring software can identify:
The key to preventing costly failures lies in the ability to detect subtle anomalies that precede such events. By harnessing the power of artificial intelligence (AI) and machine learning, modern predictive maintenance software can analyse vast amounts of data from equipment sensors to pinpoint patterns indicative of impending failures.
At the core of this AI-driven solution is a sophisticated algorithm that continuously monitors data streams from critical components. This data encompasses a wide range of parameters, including temperature, pressure, vibration, and electrical signals. The AI model is trained to recognise normal operating patterns and identify deviations that may signal potential issues.
Here’s another common question; Why is AI better than thresholds that are traditionally used in SCADA systems?
AI-powered predictive maintenance models offer significant advantages over traditional threshold-based monitoring systems. While conventional systems rely on pre-set thresholds based on generic motor classifications, AI models learn from your specific equipment's actual operating patterns. This contextual learning is crucial because each production facility operates its assets differently, making standardised thresholds less effective. This is especially true for production related equipment; if you run multiple different products on the same lines (a common occurrence for brands that market many different flavours, and with marketing departments that like to create punchy temporary products), than thresholds will fire off lots of false positives when a new product that is more demanding on your equipment starts to get produced.
For equipment that operate with a more consistent operational profile, AI's more sophisticated pattern recognition capabilities can detect subtle changes in equipment behaviour long before they would trigger traditional thresholds. This enhanced sensitivity provides maintenance teams with greater lead time to plan and execute repairs, shifting from reactive maintenance to truly predictive interventions. The AI approach also eliminates the complicated and often imprecise process of manually setting and adjusting threshold values, resulting in more accurate and site-specific early warning detection.
While manual vibration inspections have traditionally been a cornerstone of maintenance programs, online condition monitoring offers significant advantages for yogurt producers. Manual inspections, typically performed monthly or quarterly, can miss critical developments that occur between measurements. Here's why continuous online monitoring represents a crucial upgrade for modern production facilities:
Some equipment failures can develop rapidly, especially in high-speed production environments. A bearing might show normal readings during a monthly inspection but fail catastrophically just days later. Online condition monitoring software provides continuous oversight, catching sudden changes in equipment health that manual inspections might miss.
Manual inspections provide only periodic snapshots of machine health, making it difficult to identify subtle trends or patterns. Online monitoring captures continuous data streams, enabling advanced analysis of:
Online monitoring systems can correlate equipment behaviour with actual production conditions. This context is invaluable for understanding how different product types, speeds, and operating parameters affect machine health - insights that are impossible to gather from periodic manual measurements.
While manual inspections require significant time and labour investment, online condition monitoring software can monitor hundreds of assets simultaneously. This allows maintenance teams to:
In round-the-clock production environments, equipment failures don't wait for scheduled inspection times. Online monitoring provides constant vigilance, ensuring that potential issues are flagged immediately, regardless of the time of day or day of the week.
By combining continuous monitoring with machine learning algorithms, modern predictive maintenance software can:
Online monitoring systems can integrate with broader production management software, enabling:
Taking the first step towards implementing an AI-powered predictive maintenance program can seem daunting. However, with the right approach and a trusted partner, you can unlock significant cost savings, increase asset reliability, and optimise your maintenance operations.
Key considerations include:
By following these steps and partnering with an experienced predictive maintenance provider, you can unlock the full potential of AI-driven maintenance, reducing downtime, minimising product loss, and maximising the lifespan of your critical assets.
