In the production of explosives where safety is paramount, the equipment used must meet the highest standards of reliability, precision, and compliance. One of the most critical machines in this process is the sigma mixer, also known as the Z blade mixer—a proven solution for handling high-viscosity, potentially hazardous materials.
At Karvil Machinery, we have been specializing in the design and manufacturing of industrial sigma mixers. Our sigma mixers are exported to more than 50 countries worldwide and have earned the trust of clients operating in high-risk sectors. For explosive applications, our mixers are available with full ATEX certification, ensuring safe operation in potentially explosive atmospheres.
Explosives, whether military-grade or used in civil blasting operations, often consist of a complex mix of powders, binders, plasticizers, and stabilizers. These materials are not only sticky and dense but also sensitive to friction, pressure, and temperature. The sigma mixer is uniquely suited for this task due to its:
Robust double sigma blades: Ideal for uniform kneading and dispersion of solid-liquid components.
Vacuum sealing and temperature control: Prevents contamination, reduces oxidation risk, and ensures thermal stability throughout the process.
Explosion-proof configurations: Equipped with flameproof motors, grounded connections, anti-static materials, and pressure relief systems to comply with ATEX directives.
ATEX-Certified Safety for Hazardous Zones
ATEX (Atmosphères Explosibles) certification is essential for equipment operating in environments where combustible gases, vapors, or dusts may be present. Our Explosion-proof sigma mixers are engineered for use in the production of explosives, ensuring peace of mind for operators and plant managers alike.
Sealed electrical enclosures
Temperature and pressure monitoring systems
Custom-engineered jackets for cooling or heating
Stainless steel contact parts, polished to high-grade finishes for safe cleaning
From Europe and the Middle East to South America and Southeast Asia, Karvil Machinery has delivered Customizable sigma mixers to meet diverse client requirements. For customers in the explosive sector, we offer project-specific engineering, ensuring that every machine integrates seamlessly into your safety protocols and production goals.
Whether you are mixing emulsion explosives, slurry gels, or solid propellant bases, Karvil’s sigma mixers provide a balance of precision, durability, and certified safety.
Conclusion:
Working with sensitive materials like explosives demands more than just mixing—it requires a deep understanding of both materials behavior and safety engineering. With our extensive experience and ATEX-certified solutions, Karvil Machinery stands ready to support explosive manufacturers in building safe, efficient, and compliant production lines.
