In industries such as food, pharmaceuticals, chemicals, and petrochemicals, dynamic mixers are critical production tools. They ensure the consistent mixing of raw materials and the quality of the final product. However, malfunctions or downtime of these systems can lead to significant financial and operational losses.
Downtime costs are the direct and indirect losses resulting from equipment failures or production downtimes. These costs can be extremely high for dynamic mixers, as these devices often form the backbone of a production line.
In this article, we will comprehensively discuss the concept of dynamic mixer failure costs, the factors that influence them, calculation methods, and solutions to reduce these costs.
The importance of dynamic mixers in industry
Before we consider the cost of downtime, it is important to better understand the role of dynamic mixers:
-
In the food industry, it is used to produce products such as sauces, beverages, dairy products and chocolate.
-
In the pharmaceutical industry it is used to evenly mix active ingredients and excipients .
-
In the chemical and petrochemical industries, it is used for mixing polymers, resins and concentrated chemicals.
Since the dynamic mixer is directly related to the quality of the final product, its failure or downtime means the downtime of the entire production line.
How much does the stop cost?
Production downtime costs include all losses resulting from unexpected or unplanned production interruptions. These costs are typically divided into four categories:
-
Direct production costs: include losses resulting from production interruptions per unit of time.
-
Maintenance costs: include the cost of spare parts and labor costs to fix the problem .
-
Indirect costs: such as reduced productivity or delayed order delivery.
-
Opportunity costs: Loss of sales or new customers due to reduced production capacity.
Factors influencing the cost of dynamic mixer failure
1. Production capacity and production volume
The higher the productivity of a production line, the greater the losses due to downtime of dynamic mixers. In a food factory with a daily production volume of 50 tons, for example, a two-hour downtime can result in the loss of several tons of product.
2. Cost of the final products
If the product is high-value (e.g. pharmaceuticals or certain polymers), the costs of stopping production increase considerably.
3. Repair time
The time required to repair the faucet and restore it to working order determines the cost of downtime.
4. Receipt of spare parts
Bottlenecks or delays in the supply of spare parts can lead to significant downtime and increased costs.
5. The degree of dependence of the production line on the mixer.
In some industries, a production line without a dynamic mixer is virtually useless. In such cases, the slightest disruption can lead to a complete production shutdown.
How to calculate the failure costs of a dynamic mixer
To accurately calculate the cost of downtime, several criteria must be considered . A common calculation method is as follows:
Cost of downtime = (production downtime x product cost) + maintenance cost + opportunity cost
Numerical example
Let’s take a pharmaceutical factory:
-
Productivity: 1000 kg/h
-
Product price per kilogram : 50 US dollars
-
Duration: 3 hours
-
Cost of repairs and spare parts: $5,000
Production loss = 1000 x 50 x 3 = $ 150,000 Repair costs = $5,000 Opportunity costs (loss of export contract) = $20,000
The total cost of downtime due to a single error was $175,000!
Consequences of stopping a dynamic mixer
1. Financial consequences
-
Decline in the company’s profitability
-
Rising costs for emergency repairs
-
Loss of customers due to delivery delays
2. Operational impacts
-
Causes jams in the production line
-
Increased load on other devices
3. Qualitative value
-
Possible loss of semi-finished products
-
Reduced quality of the final product due to interruptions in the mixing process.
Strategies to reduce failure costs in the production of dynamic mixers
1. Preventive Maintenance (PM)
-
Check the engine regularly.
-
Replace bearings, seals and other wear parts in a timely manner.
-
Use suitable lubricants.
2. Predictive maintenance
-
Use vibration and temperature sensors to monitor equipment condition.
-
Predicting failures through data analysis
3. Staff training
-
Training of operators in the correct operation of the equipment
-
Training maintenance teams for rapid response to emergency situations
4. Spare parts supply
-
Create a strategic spare parts warehouse
-
Engaging reliable suppliers for fast delivery
5. Robust construction and selection of standard equipment
-
Use engines manufactured according to international standards such as API or GMP.
-
Use corrosion- and wear-resistant materials to extend the life of your equipment.
Comparison of failure costs of dynamic mixers and other devices
| equipment | Possibility to stop | Costs of downtime in sensitive industries |
|---|---|---|
| dynamic mixer | high (due to its importance) | Very |
| Centrifugal pumps | half | half |
| transport system | half | half |
| Peripherals | a little | fewer |
As the table shows , dynamic mixers have the greatest impact on failure costs .
Practical examples of downtime costs
1. Food industry
At a sauce factory, a five-hour outage of a dynamic mixer resulted in the loss of 20 tons of unfinished products valued at over $40,000.
2. Pharmaceutical industry
A malfunction of a dynamic mixer in an antibiotic production line resulted in a two-hour production stoppage, rendering the entire batch unusable . The total cost of lost raw materials and missed opportunities exceeded $300,000.
3. Petrochemical industry
The failure of a dynamic mixer and a shortage of spare parts resulted in a two-day shutdown of the resin production plant, costing the company approximately $1 million .
The future of dynamic cost management in the event of engine failure
Thanks to technological advances, many industries are moving towards intelligent monitoring systems and the Industrial Internet of Things (IIoT).
-
These technologies enable device monitoring and failure prediction in real time.
-
The result is lower downtime costs and higher productivity.
Finally
The cost of dynamic mixer downtime is one of the most serious problems facing the manufacturing industry . These costs include production downtime, repair costs, job losses, and productivity losses.
Solutions such as preventive maintenance, the use of condition monitoring technologies, employee training and the availability of spare parts can significantly reduce these costs.
Ultimately, considering failure costs is not just an economic decision, but a strategic necessity for survival and competitiveness in the global market.
