Easy-Clean Sigma Mixers & Extruders for Hazardous Areas

Processing hazardous, reactive, or high-energy materials leaves no margin for compromise. Equipment must deliver controlled mixing, operator protection, and efficient cleanability—every cycle, every batch.

The Easy-Clean Sigma Mixer Extruder by PerMix is purpose-engineered for hazardous-area operation, combining high-torque sigma blade mixing with integrated extrusion and a design that prioritizes safety, containment, and uptime.

This is not a standard sigma mixer adapted for risk.
It is a hazardous-duty system designed from the start to operate where consequences matter.


Built for Hazardous & High-Risk Processing

Sigma mixers are the gold standard for dense, sticky, and shear-sensitive materials. In hazardous environments, that performance must be paired with robust containment and disciplined engineering.

The PerMix Easy-Clean Sigma Mixer Extruder is designed for:

  • Reactive and energetic materials
  • Solvent-based and volatile formulations
  • High-viscosity pastes, doughs, and slurries
  • Applications requiring controlled extrusion and discharge

From batch charging through mixing, extrusion, and cleaning, every element is engineered to reduce exposure and improve operational confidence.


Easy-Clean Design That Improves Safety & Uptime

In hazardous processing, cleaning is not a secondary task—it is a safety function.

PerMix’s Easy-Clean architecture provides rapid, direct access to product-contact zones, reducing:

  • Operator exposure during clean-out
  • Time required for batch changeover
  • Risk during inspection, validation, and maintenance

By simplifying access without sacrificing containment or structural integrity, the system helps manufacturers maintain compliance while maximizing productivity.


Integrated Sigma Mixing & Extrusion

This system combines:

  • High-torque, counter-rotating sigma blades for intensive mixing
  • Precise temperature control options (heating and cooling jackets available)
  • Integrated extrusion for controlled downstream forming or discharge

The result is consistent product quality, repeatable batch performance, and seamless transition from mixing to extrusion—all within a single, engineered platform.


Designed for Demanding Industries

The Easy-Clean Sigma Mixer Extruder is used across industries where safety, repeatability, and accountability are critical:

  • Chemical processing
  • Pharmaceutical and specialty compounds
  • Energetic and hazardous materials
  • Battery and advanced material production
  • Defense and high-security manufacturing

Engineered for Reality, Not Just Specifications

Hazardous environments don’t allow shortcuts.
Downtime is expensive.
Cleaning impacts safety.

PerMix designs equipment that acknowledges those realities—and engineers solutions that protect people, product, and process.

If your application involves risk, complexity, or materials that refuse to behave, this is the level of engineering it deserves.
