Understanding the combustible characteristics of dust is crucial for assessing facility risks and designing effective protection systems. We provides comprehensive dust testing services. Villo’advanced lab identifies and measures key explosibility parameters like Pmax, Kst, MIE, and MIT. With this critical data, we tailor-design and implement the most suitable explosion protection solutions, ensuring operational safety and reliability.
About Villo Envsafe
Villo Envsafe Testing Center, accredited by the China National Accreditation Service for Conformity (CNAS), is the first and only private Combustible Dust Testing Lab in China. This cutting-edge facility offers precise and comprehensive dust testing, providing essential data for designing effective explosion protection systems.
Why Dust Test?
Testing your dust is essential for compliance with local safety standards and ensuring the safety of your industrial process. It helps to:
Discover Dust Hazards
Identify where dust hazards exist in your process.
Exclusive Explosion Protection
Design explosion protection tailored to your specific hazards.
Improve Manufacturing Processes
Implement process improvements to reduce risk.
Dust Testing Process
We can help you choose and perform the dust tests tailored to your process and safety goals:
01
Combustible Dust Screening Test
The test determines if a dust sample is combustible. If combustible, further tests identify explosive parameters for protection design. Non-combustible samples don't require specific explosion protection.
02
Maximum Explosion Pressure and Explosion Index
Pmax and KSt indicate an explosion's destructive force. These parameters are essential for designing explosion venting, isolation, suppression, and resistant containers.
LEL/MEC is the minimum dust concentration for self-sustaining combustion. It guides dust collection system design and cleaning frequency determination.
04
Minimum Oxygen Concentration (LOC)
LOC is the lowest oxygen level for flame propagation in a dust cloud. It's crucial for designing inert gas blanketing systems for explosion prevention.
05
Minimum Ignition Energy (MIE)
MIE is the least energy needed to ignite a dust cloud. It's used to choose explosion prevention methods. High MIE (> 1 J) means relative safety; low MIE (< 10 mJ) indicates high ignitability.
06
Minimum Ignition Temperature of a Dust Cloud (MIT-C)
MIT-C is the lowest temperature at which a dust cloud can ignite. It's used to select explosion-proof electrical equipment and control hot surface temperatures.
07
Minimum Ignition Temperature of a Dust Layer (MIT-L)
MIT-L is the lowest temperature at which a dust layer can ignite. It's used for choosing explosion-proof electrical equipment and managing hot surface temperatures.
08
Autoignition Temperature of Accumulated Dust
This controls environmental temperature in areas where dust accumulates, preventing self-ignition.
09
Dust Resistivity
Dust resistivity helps control static discharge, design static electricity precipitators, select explosion-proof equipment, and evaluate static electricity risks. Conductivity is its reciprocal.
